1. Solution

• Short answer
  • Yes, you can run multiple instances of the same application (or multiple background workers) with ABP’s Inbox/Outbox enabled and safely consume from the same Inbox. ABP uses a distributed lock and idempotency to prevent double handling. This supports horizontal scale-out while preserving at-least-once delivery semantics.
  • Concurrency control/protections:
    • Outbox: Background publisher is protected by a distributed lock to avoid concurrent publishing of the same outbox record across instances.
    • Inbox: Each received distributed event is stored first and deduplicated (idempotency check) before handlers run; a distributed lock is taken around processing to avoid concurrent execution of the same inbox record by multiple instances.
• What you must do
  1. Use a distributed lock provider (mandatory for multi-instance):
     • Install an IDistributedLockProvider implementation (e.g., Redis, SqlServer, etc.) and register it once at startup:

using Medallion.Threading;
     using Medallion.Threading.Redis;
     using StackExchange.Redis;

     context.Services.AddSingleton<IDistributedLockProvider>(sp =>
     {
         var configuration = context.Services.GetConfiguration();
         var mux = ConnectionMultiplexer.Connect(configuration["Redis:Configuration"]); // e.g., "127.0.0.1"
         return new RedisDistributedSynchronizationProvider(mux.GetDatabase());
     });

 - Ensure all instances share the same distributed lock backend.

2. Configure the event boxes per DB context:

Configure<AbpDistributedEventBusOptions>(options =>
     {
         options.Outboxes.Configure(config => { config.UseDbContext<MyDbContext>(); });
         options.Inboxes.Configure(config => { config.UseDbContext<MyDbContext>(); });
     });

 - Outbox/Inbox tables must live in the same database as your business data to execute in a single transaction.

3. Run as many instances as needed. ABP’s background workers will:
   • Outbox: only one instance acquires the lock to publish a specific batch/record at a time; retries handle transient failures.
   • Inbox: the message is persisted first; duplicate deliveries are discarded using the stored processed record; processing is wrapped with a lock to avoid concurrent execution for the same message.

• On duplicates and ordering

  • The pattern is at-least-once. Duplicates can still be delivered by the broker, but the inbox idempotency record prevents re-processing. Your handlers should be idempotent (safe on re-run) as a best practice.
  • Ordering across partitions/consumers is not guaranteed by ABP; rely on your broker or design handlers to be order-independent.

• If you need higher parallelism

  • Use your broker’s partitioning/competing-consumers capabilities (e.g., RabbitMQ multiple consumers on a queue, Kafka partitions) – ABP’s inbox will still dedupe.
  • Use selectors (EventSelector/HandlerSelector) to split inboxes per module or message category to reduce contention.
  • For extreme multi-database/multi-tenant scenarios, consider a specialized implementation (e.g., custom IEventInbox/IEventOutbox provider), but it’s not required for typical scaling.

• Not supported/out-of-scope

  • Exactly-once processing is not provided; ABP provides at-least-once with idempotency and distributed locking.

1. Solution Below is a concise, practical guide to the abp suite generate CLI command that lets you run ABP Suite’s CRUD code generation from the command line using a JSON entity definition file.

Prerequisites

• ABP Suite installed (with a valid license for ABP Commercial).
• ABP CLI installed: dotnet tool install -g Volo.Abp.Cli
• An ABP solution (the .sln path you’ll pass with -s).
• A Suite entity JSON file (the model describing your entity, properties, UI preferences, etc.).

Command abp suite generate -e <entity-json-path> -s <solution-sln-path> [options]

Required parameters

• -e, --entity: Path to the Suite entity definition JSON file.
• -s, --solution: Path to your solution (.sln) file that will be modified (server and UI code generated/inserted).

Common options

• --ui angular|mvc|blazor: Forces a specific UI target if your solution contains multiple UIs or if you want to generate for one UI only.
• --overwrite true|false: Overwrite existing generated files (default is safer behavior; set true to refresh generated code).
• --dry-run true|false: Shows what would be generated without writing files (useful to review).
• --module <ModuleName>: Generate into a specific module of a modular solution.
• --include-tests true|false: Generate corresponding test projects and tests where supported.

Typical usage examples

1. Basic generation (single module, single UI) abp suite generate -e C:\Users&lt;you>.suite\entities\Country.json -s C:\dev\MyApp\MyApp.sln

2. Generate only for Angular UI abp suite generate -e ..suite\entities\Product.json -s .\MyApp.sln --ui angular

3. Overwrite previously generated files (refresh after entity changes) abp suite generate -e ..suite\entities\Order.json -s .\MyApp.sln --overwrite true

4. Dry run to preview changes abp suite generate -e ..suite\entities\Customer.json -s .\MyApp.sln --dry-run true

5. Generate into a specific module in a modular solution abp suite generate -e ..suite\entities\Invoice.json -s .\MyMicroserviceApp.sln --module AccountingService

What the command does

• Reads your entity JSON and generates end-to-end code:
  • Domain, EF Core mapping, repository, application contracts, application service, HTTP API.
  • UI pages/components (Angular/MVC/Blazor) for CRUD, navigation entries, menus, localization entries, permissions.
  • Optionally test scaffolding.
• Integrates with existing solution structure created by ABP templates.
• Respects ABP best practices (DTOs, permissions, validation, application services, layered architecture).

Authoring the entity JSON A minimal example to get started (Country.json): { "name": "Country", "namespace": "MyCompany.MyApp", "tableName": "AppCountries", "primaryKey": "Guid", "aggregateRoot": true, "audited": true, "fields": [ { "name": "Name", "type": "string", "maxLength": 128, "required": true }, { "name": "Code", "type": "string", "maxLength": 8, "required": true, "unique": true } ], "ui": { "create": { "visible": true }, "edit": { "visible": true }, "delete": { "visible": true }, "list": { "columns": [ { "name": "Name", "width": 200 }, { "name": "Code", "width": 120 } ] } }, "permissions": { "groupName": "Country", "default": "MyApp.Countries", "create": "MyApp.Countries.Create", "update": "MyApp.Countries.Update", "delete": "MyApp.Countries.Delete" } }

Recommended workflow

• Create/update your entity JSON definition (use ABP Suite UI once to export JSON, or author by hand following your established patterns).
• Keep entity JSON files under a .suite/entities folder in your repo to version-control them.
• Run abp suite generate whenever your entity model changes.
• Use --dry-run first to verify, then run with --overwrite true if you are refreshing generated files.
• After generation, run database migrations if entity/schema changes were included:
  • Add migration: dotnet ef migrations add "Added_Country" -p <Your.DbMigrationsProject> -s <Your.HttpApi.Host>
  • Update database: dotnet ef database update -p <Your.DbMigrationsProject> -s <Your.HttpApi.Host>
• Build and run your app; verify the new menu and CRUD pages.

Troubleshooting tips

• The solution path (-s) must point to an existing .sln from an ABP-based solution; ensure the UI project exists if you target a specific UI.
• If you have customizations on generated files, they may be overwritten when using --overwrite true; consider partial classes/partials/partial methods, or keep custom code out of generated regions/files.
• Ensure your ABP Suite version matches your solution’s ABP version range to avoid template incompatibilities.
• Run from a developer command prompt with write permissions to your repo.

1. Solution

• Keep ABP Identity’s default behavior, but stop emitting all roles for every user. ABP doesn’t need role claims in the cookie to authorize permissions; it evaluates permissions server-side. So, minimize role claims while preserving Identity/permission functionality.

• Option A (recommended): Do not add any role claims at sign-in; rely on ABP permission system

  • Implement an IAbpClaimsPrincipalContributor that removes role claims from the cookie while leaving everything else intact. ABP Identity and permission checks still work, since permission evaluation queries stores/caches, not the cookie’s entire role list.

using System.Linq;
  using System.Security.Claims;
  using System.Threading.Tasks;
  using Microsoft.Extensions.DependencyInjection;
  using Volo.Abp.DependencyInjection;
  using Volo.Abp.Security.Claims;

  public class RemoveBulkRoleClaimsContributor : IAbpClaimsPrincipalContributor, ITransientDependency
  {
      public Task ContributeAsync(AbpClaimsPrincipalContributorContext context)
      {
          var identity = context.ClaimsPrincipal.Identities.FirstOrDefault();
          if (identity == null) return Task.CompletedTask;

          // Remove pre-added role claims to reduce cookie size
          var roleClaims = identity.FindAll(AbpClaimTypes.Role).ToList();
          foreach (var c in roleClaims)
          {
              identity.TryRemoveClaim(c);
          }

          // Optionally add only a marker claim (tiny) if your app needs to know user has roles
          // identity.AddClaim(new Claim("has_roles", "true"));

          return Task.CompletedTask;
      }
  }

• Register the contributor in your AuthServer/HttpApi.Host module:

using Volo.Abp.Modularity;
  using Volo.Abp.Security.Claims;

  public class YourAuthServerModule : AbpModule
  {
      public override void ConfigureServices(ServiceConfigurationContext context)
      {
          Configure<AbpClaimsPrincipalFactoryOptions>(options =>
          {
              options.Contributors.Add<RemoveBulkRoleClaimsContributor>();
          });
      }
  }

• Option B (if you must keep role claims, include only roles assigned to the current user)
  • Replace “all roles” with “user’s roles only,” which keeps ABP Identity roles intact but dramatically reduces the count:

using System.Linq;
  using System.Security.Claims;
  using System.Threading.Tasks;
  using Microsoft.Extensions.DependencyInjection;
  using Volo.Abp.DependencyInjection;
  using Volo.Abp.Identity;
  using Volo.Abp.Security.Claims;
  using Volo.Abp.Users;

  public class UserOnlyRolesClaimsContributor : IAbpClaimsPrincipalContributor, ITransientDependency
  {
      public async Task ContributeAsync(AbpClaimsPrincipalContributorContext context)
      {
          var identity = context.ClaimsPrincipal.Identities.FirstOrDefault();
          if (identity == null) return;

          // Remove any pre-added Role claims first
          var existingRoleClaims = identity.FindAll(AbpClaimTypes.Role).ToList();
          foreach (var c in existingRoleClaims)
          {
              identity.TryRemoveClaim(c);
          }

          var userId = identity.FindUserId();
          if (!userId.HasValue) return;

          var userRoleFinder = context.ServiceProvider.GetRequiredService<IIdentityUserRoleFinder>();
          var roleRepository = context.ServiceProvider.GetRequiredService<IIdentityRoleRepository>();

          var roleIds = await userRoleFinder.GetRoleIdsAsync(userId.Value);
          if (!roleIds.Any()) return;

          var roles = await roleRepository.GetListAsync(roleIds);
          foreach (var role in roles)
          {
              identity.AddClaim(new Claim(AbpClaimTypes.Role, role.Name));
          }
      }
  }

• Register similarly via AbpClaimsPrincipalFactoryOptions.

• Option C (compact roles into a single small claim)

  • If you need roles in the client but must keep the cookie tiny, replace multiple role claims with one compact claim (e.g., CSV or short IDs) and read it in your UI. Note: ASP.NET Core’s built-in [Authorize(Roles="...")] expects standard role claims, so if you compact them, you’ll need a custom IAuthorizationPolicyProvider/ClaimsTransformation to interpret it.

• If you use OpenIddict/JWT for SPA:

  • Put roles only in the access_token (API use) and keep id_token/cookie minimal. You can control token claims via OpenIddict server events (e.g., ProcessSignInContext) to avoid bloating cookies while still letting APIs receive roles.

• General tips to avoid “request header too long”:

  • Prefer permission checks over role claims in cookies.
  • Avoid adding per-permission claims; check permissions server-side.
  • Reduce or eliminate large custom claims in the cookie.

1. Solution

• Root cause: You are issuing too many claims into the authentication ticket (cookie). In ABP/ASP.NET Core Identity, role claims are added by the claims principal factory. You can fully control which role claims are emitted and reduce cookie size by customizing ABP’s claims principal pipeline.

• Recommended approach: Implement an IAbpClaimsPrincipalContributor that only adds the roles for the current user (and optionally, compresses or limits them) and removes any global/bulk role claims. Register it in your HttpApi.Host/AuthServer.

Example: Only include roles assigned to the current user and limit count

using System.Linq;
using System.Security.Claims;
using System.Threading.Tasks;
using Microsoft.Extensions.DependencyInjection;
using Volo.Abp.DependencyInjection;
using Volo.Abp.Security.Claims;
using Volo.Abp.Users;
using Volo.Abp.Identity;
using Volo.Abp;

public class MinimalRolesClaimsContributor : IAbpClaimsPrincipalContributor, ITransientDependency
{
    // Adjust as needed
    private const int MaxRolesToInclude = 20;

    public async Task ContributeAsync(AbpClaimsPrincipalContributorContext context)
    {
        var identity = context.ClaimsPrincipal.Identities.FirstOrDefault();
        if (identity == null)
        {
            return;
        }

        // 1) Remove any pre-added Role claims to avoid duplication or global roles
        var existingRoleClaims = identity.FindAll(AbpClaimTypes.Role).ToList();
        foreach (var c in existingRoleClaims)
        {
            identity.TryRemoveClaim(c);
        }

        // 2) Add only current user's roles (optionally limit the count)
        var userId = identity.FindUserId();
        if (!userId.HasValue)
        {
            return;
        }

        var userRoleFinder = context.ServiceProvider.GetRequiredService<IIdentityUserRoleFinder>();
        var roleRepository = context.ServiceProvider.GetRequiredService<IIdentityRoleRepository>();

        // Get role IDs for the user
        var roleIds = await userRoleFinder.GetRoleIdsAsync(userId.Value);

        // Load roles and order deterministically
        var roles = await roleRepository.GetListAsync(roleIds);
        var roleNames = roles
            .Select(r => r.Name)
            .OrderBy(n => n)
            .Take(MaxRolesToInclude)
            .ToList();

        foreach (var roleName in roleNames)
        {
            identity.AddClaim(new Claim(AbpClaimTypes.Role, roleName));
        }

        // Optional: If you want to avoid multiple Role claims, you can add a single compact claim:
        // identity.AddClaim(new Claim("roles_csv", string.Join(",", roleNames)));
        // Then, customize your authorization policy provider to read from this single claim instead of multiple Role claims.
    }
}

• Register the contributor in your module (e.g., in your HttpApi.Host/AuthServer module):

using Microsoft.Extensions.DependencyInjection;
using Volo.Abp.Modularity;
using Volo.Abp.Security.Claims;

[DependsOn(typeof(AbpIdentityHttpApiModule))] // or your relevant modules
public class YourHostModule : AbpModule
{
    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        Configure<AbpClaimsPrincipalFactoryOptions>(options =>
        {
            // Add our contributor at the end (or earlier if you want to override earlier contributors)
            options.Contributors.Add<MinimalRolesClaimsContributor>();
        });
    }
}

• Additional tactics to reduce header/cookie size:
  • If you’re using cookie auth, prefer sliding expiration and keep claims minimal. Move large, infrequently used data out of the cookie and load on demand from DB.
  • If using OpenIddict/IdentityServer, keep id_token small; put roles only in access_token when necessary and for APIs. For SPA/React, you don’t need to send all roles in cookies if you can authorize on the server using permissions.
  • Prefer permission checks (ABP’s permission system) instead of flooding the cookie with thousands of Role claims. Permissions are evaluated server-side and cached.
  • If you must keep all permissions/roles, consider JWT access tokens for the SPA and keep the cookie (for server) lean, or store roles compactly (e.g., single CSV claim or hashed/bitset mapping) and adapt your authorization policy provider.

1. Solution

• In LeptonX Angular, the header is composed of replaceable building blocks. To place your route menu (top navigation) between the company logo (lpx-header-top) and the right user toolbar (lpx-right-menu), create a custom layout that reorders these blocks, then use it instead of the built-in layout.

Steps:

1. Create a custom layout component and register it

• Generate a layout component (e.g., AppCustomTopLayoutComponent) and mark it as a layout replacement.
• Import LeptonX layout/component modules you will use.

// app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

// LeptonX modules you will need in the template
import { LpxTopMenuLayoutModule, LpxSideMenuLayoutModule } from '@volosoft/ngx-lepton-x/layouts';
import {
  LpxNavbarModule,
  LpxBrandLogoModule,
  LpxTopbarModule,
  LpxTopbarContentModule,
  LpxToolbarContainerModule,
  LpxAvatarModule,
  LpxSettingsModule,
  LpxBreadcrumbModule,
  LpxFooterModule
} from '@volosoft/ngx-lepton-x/components';
import { LpxResponsiveModule } from '@volo/ngx-lepton-x.core';

import { AppCustomTopLayoutComponent } from './layouts/app-custom-top-layout.component';

@NgModule({
  declarations: [AppCustomTopLayoutComponent],
  imports: [
    BrowserModule,
    // Import the LeptonX modules (pick what you actually use)
    LpxTopMenuLayoutModule,
    LpxSideMenuLayoutModule,
    LpxNavbarModule,
    LpxBrandLogoModule,
    LpxTopbarModule,
    LpxTopbarContentModule,
    LpxToolbarContainerModule,
    LpxAvatarModule,
    LpxSettingsModule,
    LpxBreadcrumbModule,
    LpxFooterModule,
    LpxResponsiveModule
  ],
  bootstrap: [/* ... */]
})
export class AppModule {}

2. Build the custom header composition with “menu between logo and user toolbar”

• In your custom layout template, place lpx-navbar (your routes/top menu) between lpx-brand-logo and the right-side toolbar container.

<!-- app-custom-top-layout.component.html -->
<div id="lpx-wrapper">
  <div class="lpx-content-container">
    <div class="lpx-topbar-container">
      <div class="lpx-topbar">
        <!-- Left: Logo -->
        <div class="lpx-header-top">
          <lpx-brand-logo></lpx-brand-logo>
        </div>

        <!-- Center: Routes (Top Menu Navbar) -->
        <div class="lpx-top-menu-navbar">
          <lpx-navbar></lpx-navbar>
        </div>

        <!-- Right: User/Settings toolbar -->
        <div class="lpx-right-menu">
          <lpx-toolbar-container></lpx-toolbar-container>
          <lpx-avatar></lpx-avatar>
          <lpx-settings></lpx-settings>
        </div>
      </div>
    </div>

    <!-- Optional: Breadcrumb under header -->
    <div class="lpx-breadcrumb-container">
      <lpx-breadcrumb></lpx-breadcrumb>
    </div>

    <!-- Page content -->
    <div class="lpx-content-wrapper">
      <div class="lpx-content">
        <router-outlet></router-outlet>
      </div>
    </div>

    <div class="lpx-footbar-container">
      <lpx-footer></lpx-footer>
    </div>
  </div>

  <!-- Mobile navbar if needed -->
  <lpx-mobile-navbar *lpxResponsive="'all md-none'"></lpx-mobile-navbar>
</div>

3. Make this layout active

• Use Angular Component Replacement to replace the default layout with your custom one, or route specific pages to use it.

Example (replace main layout globally):

// app-routing.module.ts (example)
const routes: Routes = [
  {
    path: '',
    component: AppCustomTopLayoutComponent,
    children: [
      // your app routes here
    ],
  },
];

4. If you were using the packaged Top Menu layout already

• Ensure you use the top-menu style assets and module:
  • In angular.json, set style to top-menu (instead of side-menu).
  • In app.module.ts, use TopMenuLayoutModule if you need its styles.
• Then still compose your own header order as shown above to get “logo | routes | right toolbar”.

Notes:

• The key is composing LeptonX components manually in a custom layout and ordering them: brand logo (left), navbar (center), toolbar/avatar/settings (right).
• This approach follows ABP’s “Component Replacement” and LeptonX customization guidance.

1. Solution Your log shows StackExchange.Redis timing out on HMGET while ABP is trying to read the cached ApplicationConfigurationDto (the /api/abp/application-configuration pipeline). These timeouts are almost always infrastructure/configuration issues around Redis connectivity, load, or client timeout settings rather than ABP code defects. Apply the following, in order:

• Verify Redis health and networking

  • Ensure the Redis endpoint is reachable from the app containers/VMs (latency, packet loss, firewall/NAT).
  • Check Redis CPU, slowlog, and INFO stats for command latency or blocking operations.
  • If running in containers/K8s, confirm there’s no DNS flap or intermittent network policy drops.

• Increase StackExchange.Redis timeouts conservatively

  • In appsettings.json (or environment), add a Redis configuration string with larger timeouts: { "Redis": { "Configuration": "10.166.0.97:6379,abortConnect=false,connectRetry=5,connectTimeout=10000,syncTimeout=10000,responseTimeout=10000,keepAlive=60,allowAdmin=false" } } Notes:
  • responseTimeout (v2.6+) is preferred; syncTimeout applies to some paths. Keep both aligned.
  • connectRetry and connectTimeout help on transient network issues.
  • keepAlive helps long-lived connections in some networks.

• Use ABP’s Redis integration package and set a key prefix

  • Ensure the Web (and Auth/Tiered) projects reference:
    • Volo.Abp.Caching.StackExchangeRedis
  • Configure distributed cache and a clear key prefix to avoid collisions: public override void ConfigureServices(ServiceConfigurationContext context) { Configure<AbpDistributedCacheOptions>(options => { options.KeyPrefix = "MyApp:"; // important in multi-app/shared-redis }); }

• Consider lowering load from Application Configuration

  • ApplicationConfigurationDto is read on app start for every client. If you have many concurrent clients or large DTO customizations:
    • Enable sliding/absolute expiration on the cache for that DTO to reduce Redis pressure: Configure<AbpDistributedCacheOptions>(options => { options.GlobalCacheEntryOptions.SlidingExpiration = TimeSpan.FromMinutes(10); });
    • Avoid heavy custom logic inside your overridden AbpApplicationConfigurationAppService.GetAsync that triggers multiple DB or cache calls per request; pre-aggregate, cache sub-parts, or compute once and cache with a reasonable TTL.
    • If you added custom data (like module permission maps), cache them separately with GetOrAddAsync and short TTLs, then compose the DTO from cached pieces.

• Prevent cache operations from being cancelled by request aborts

  • If frontends sometimes cancel requests (navigation, timeouts), that cancellation token may bubble into Redis calls. Consider isolating cancellation tokens for cache access: public class NoCancelTokenProvider : ICancellationTokenProvider, ISingletonDependency { public CancellationToken Token => CancellationToken.None; public IDisposable Use(CancellationToken cancellationToken) => NullDisposable.Instance; private sealed class NullDisposable : IDisposable { public static readonly NullDisposable Instance = new(); public void Dispose() { } } }
  • Or wrap hot cache calls with CancellationToken.None explicitly in your own logic where safe.

• Check thread pool starvation and blocking code

  • Your log shows WORKER Busy=99 and queued items, which can exacerbate Redis timeouts under load.
  • Audit for synchronous blocking (Result/Wait) on async methods, long GC pauses, or CPU saturation.
  • Ensure ASP.NET Core ThreadPool Min/Max are not overly constrained.

• Use connection multiplexing correctly across tiered services

  • Every tier (AuthServer, API Host, Blazor Server) should point to the same Redis with the same configuration and not create unnecessary separate multiplexer instances per scope. The default DI registrations already share a singleton; avoid manual new ConnectionMultiplexer per request.

• As a last resort, raise the retry budget and use resilient Redis

  • If the environment is noisy, consider Redis Cluster/Replica, co-locate app and Redis to reduce latency, or provision higher SKU (cloud) to reduce server-side stalls.

Example minimal configuration in WebModule: [DependsOn(typeof(AbpCachingStackExchangeRedisModule))] public class MyWebModule : AbpModule { public override void ConfigureServices(ServiceConfigurationContext context) { Configure<AbpDistributedCacheOptions>(options => { options.KeyPrefix = "MyApp:"; options.GlobalCacheEntryOptions.SlidingExpiration = TimeSpan.FromMinutes(10); }); } }

1. Solution

• Short answer: Yes. Starting from ABP v8.3, you can switch ABP’s EF Core global filters (ISoftDelete, IMultiTenant, etc.) to a user-defined-function (UDF) mapping approach that removes the “(@__ef_filter__p_X = 1 OR …)” pattern and generates index-friendly predicates. You can also selectively disable filters per scope/query when needed.

• Steps (apply in your DbContext):

  1. Indicate which entities should be filtered:

protected override bool ShouldFilterEntity<TEntity>(IMutableEntityType entityType)
  {
      if (typeof(ISoftDelete).IsAssignableFrom(typeof(TEntity)) ||
          typeof(IMultiTenant).IsAssignableFrom(typeof(TEntity)))
      {
          return true;
      }

      return base.ShouldFilterEntity<TEntity>(entityType);
  }

2. Use UDF mapping for the filter so EF generates sargable SQL without the “OR @ef_filter...”:

                          if (current.Context?.DataFilter.IsEnabled<IMultiTenant>() == true)
                          {
                              // TenantId = @CurrentTenantId
                              return new SqlBinaryExpression(
                                  ExpressionType.Equal,
                                  entityTenantId,
                                  currentTenantId,
                                  entityTenantId.Type,
                                  ((SqlExpression)entityTenantId).TypeMapping);
                          }

                          return new SqlConstantExpression(Expression.Constant(true), ((SqlExpression)entityTenantId).TypeMapping);
                      });
              }

              expression = expression == null
                  ? tenantFilter
                  : QueryFilterExpressionHelper.CombineExpressions(expression, tenantFilter);
          }

          return expression;
      }

      public static bool SoftDeleteUdf(bool isDeleted, bool _)
          => throw new NotSupportedException(AbpEfCoreDataFilterDbFunctionMethods.NotSupportedExceptionMessage);

      public static bool TenantUdf(Guid? tenantId, Guid? currentTenantId)
          => throw new NotSupportedException(AbpEfCoreDataFilterDbFunctionMethods.NotSupportedExceptionMessage);

      public override string GetCompiledQueryCacheKey()
      {
          return $"{base.GetCompiledQueryCacheKey()}:{SoftDeleteEnabled}:{MultiTenantEnabled}:{CurrentTenant.Id}";
      }

      private static bool UseDbFunction() => true; // keep as feature flag if you need
  }

Resulting SQL examples:

• When filters enabled:

  • Soft delete: WHERE [IsDeleted] = 0
  • Tenant: WHERE [TenantId] = @tenantId

• When disabled: no WHERE fragment is emitted for that filter. This removes the “(@__ef_filter__p_X = 1 OR …)” form and allows index seeks on IsDeleted/TenantId aligned indexes.

• Disabling or customizing filters per scope/query:

  • Disable all soft delete (for the scope):

using (DataFilter.Disable<ISoftDelete>())
    {
        // query without soft-delete
    }

• Disable multi-tenancy (for cross-tenant maintenance, etc.):

using (DataFilter.Disable<IMultiTenant>())
    {
        // query without tenant constraint
    }

• Disable for a single LINQ operation (typical EF Core pattern):

var q = (await _repo.GetQueryableAsync())
            .IgnoreQueryFilters(); // if you really need to bypass everything

• Indexing tips:

  • Ensure indexes match the new predicates. Common patterns:
    • CREATE INDEX IX_AppTable_TenantId ON AppTable(TenantId)
    • CREATE INDEX IX_AppTable_IsDeleted ON AppTable(IsDeleted)
    • For multi-tenant tables, compound indexes often help: (TenantId, IsDeleted, <frequent column>)

• Notes:

  • The UDF methods in C# throw NotSupportedException by design; they are only placeholders for translation.
  • Remember to include the filter state in GetCompiledQueryCacheKey to avoid wrong plan caching across different filter states.

1. Solution

• You don’t need a new project. Generate AbpAuditLoggingDbContext migrations in the project that:
  • References Volo.Abp.AuditLogging.EntityFrameworkCore, and
  • Can resolve AbpAuditLoggingDbContext at design-time (either via the host as startup project or via a design-time factory).

Recommended, reliable ways:

A) Use a design-time factory (most reliable)

• Add this to your EFCore (migrations) project:

using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Design;
using Microsoft.Extensions.Configuration;
using System.IO;
using Volo.Abp.AuditLogging.EntityFrameworkCore;

public class AbpAuditLoggingDbContextFactory
    : IDesignTimeDbContextFactory<AbpAuditLoggingDbContext>
{
    public AbpAuditLoggingDbContext CreateDbContext(string[] args)
    {
        var configuration = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json", optional: true)
            .AddJsonFile("appsettings.Development.json", optional: true)
            .AddEnvironmentVariables()
            .Build();

        var cs = configuration.GetConnectionString("AbpAuditLogging")
                 ?? configuration.GetConnectionString("Default");

        var builder = new DbContextOptionsBuilder<AbpAuditLoggingDbContext>()
            .UseSqlServer(cs);

        return new AbpAuditLoggingDbContext(builder.Options);
    }
}

• Ensure this project references Volo.Abp.AuditLogging.EntityFrameworkCore.
• Run in that project folder:

dotnet ef migrations add Init_Audit_Logging \
  --context Volo.Abp.AuditLogging.EntityFrameworkCore.AbpAuditLoggingDbContext

• This creates the migration files for the audit tables in that project.

B) Use your host as startup project

• If you don’t add a factory, run from the EFCore project that references the audit EFCore package and specify the host (HttpApi.Host or DbMigrator) as startup:

dotnet ef migrations add Init_Audit_Logging \
  --project path/to/YourApp.EntityFrameworkCore \
  --startup-project path/to/YourApp.HttpApi.Host \
  --context Volo.Abp.AuditLogging.EntityFrameworkCore.AbpAuditLoggingDbContext

Requirements:

• Host config contains ConnectionStrings:AbpAuditLogging (or Default).
• Your EFCore module config includes:

Configure<AbpDbContextOptions>(opts =>
{
    opts.UseSqlServer();
    opts.Configure<Volo.Abp.AuditLogging.EntityFrameworkCore.AbpAuditLoggingDbContext>(c => c.UseSqlServer());
});

• DependsOn includes AbpAuditLoggingEntityFrameworkCoreModule.

Why you only saw the __EFMigrationsHistory table

• It’s created when EF first touches the database, but actual audit tables will be created only after you add and apply migrations for AbpAuditLoggingDbContext.

After migrations exist

• Run your single DbMigrator; it will pick up the AbpAuditLoggingDbContext migrator and create the audit tables in the AbpAuditLogging (or Default) database:

dotnet run --project src/YourApp.DbMigrator

Quick checklist

• EFCore project references Volo.Abp.AuditLogging.EntityFrameworkCore.
• Module depends on AbpAuditLoggingEntityFrameworkCoreModule and provider set via AbpDbContextOptions.
• ConnectionStrings contains AbpAuditLogging (or falls back to Default).
• Generate migrations using either A) factory or B) host as startup with fully qualified context name.

1. Solution

• No, you do not need to create a separate module or your own DbContext for auditing when you use the built-in AbpAuditLoggingDbContext. You also do not need a custom IAuditingStore. Use the provided Audit Logging module and its EF Core integration.

• Minimal, working setup to persist audit logs in a separate MSSQL database with a single DbMigrator:

  1. Add packages and module dependencies (in your EFCore project):

[DependsOn(
      typeof(Volo.Abp.EntityFrameworkCore.SqlServer.AbpEntityFrameworkCoreSqlServerModule),
      typeof(Volo.Abp.AuditLogging.EntityFrameworkCore.AbpAuditLoggingEntityFrameworkCoreModule)
  )]
  public class YourAppEntityFrameworkCoreModule : AbpModule
  {
      public override void ConfigureServices(ServiceConfigurationContext context)
      {
          Configure<AbpDbContextOptions>(options =>
          {
              // Set provider globally (covers AbpAuditLoggingDbContext too)
              options.UseSqlServer();
              // or explicitly per context if you prefer
              options.Configure<Volo.Abp.AuditLogging.EntityFrameworkCore.AbpAuditLoggingDbContext>(c =>
              {
                  c.UseSqlServer();
              });
          });
      }
  }

2. Provide a dedicated connection string named AbpAuditLogging. If it’s missing, the context falls back to Default:

{
    "ConnectionStrings": {
      "Default": "Server=.;Database=MainDb;Trusted_Connection=True;TrustServerCertificate=true",
      "AbpAuditLogging": "Server=.;Database=AuditDb;Trusted_Connection=True;TrustServerCertificate=true"
    }
  }

Put this in the appsettings.json of:

• Your DbMigrator project
• Every host that will write audit logs

3. Create migrations for AbpAuditLoggingDbContext (no custom context required). Run the command in the project that references Volo.Abp.AuditLogging.EntityFrameworkCore (you can keep these migrations in your EFCore project). If the short context name is not found, use the fully-qualified name:

dotnet ef migrations add Init_Audit_Logging \
    --context Volo.Abp.AuditLogging.EntityFrameworkCore.AbpAuditLoggingDbContext

If design-time discovery fails, add a design-time factory for AbpAuditLoggingDbContext pointing to the AbpAuditLogging connection.

4. Use a single DbMigrator. Once the AbpAuditLoggingDbContext migrations are compiled into your solution, the standard ABP DbMigrator will execute schema migrators for all registered contexts, creating and updating both MainDb and AuditDb:

dotnet run --project src/YourApp.DbMigrator

5. Ensure auditing is enabled and middleware is added in your host:

Configure<AbpAuditingOptions>(o => { o.IsEnabled = true; });
  app.UseAuditing();

• Summary:
  • Keep using the built-in AbpAuditLoggingDbContext.
  • Provide the connection string named AbpAuditLogging.
  • Generate migrations for AbpAuditLoggingDbContext.
  • Run a single DbMigrator; no extra module, no custom IAuditingStore, and no second migrator needed.

• Connection strings and named mapping (AbpAuditLogging falls back to Default if not defined):

1. Solution Below is a checklist to quickly stabilize the ABP Forms module in your setup (Angular main app hosting an MVC sub-module that contains Volo.Forms). It addresses the JSON error on create/view, the unexpected login prompts, and tenant login problems.

A) Fix the JSON error on Create/View Form

• Common cause: invalid/unsupported DTO members or circular/complex types being posted to the backend. Ensure your DTOs (inputs to create/update forms, question definitions, etc.) contain only serializable primitives/arrays and do not include System.Type or complex runtime types. If a property must exist only for internal logic, mark it to skip validation/serialization.
  • If you have a custom input with a Type property (or similar), remove it or mark it ignored/disabled for validation to avoid recursive/serializer issues:

public class MyFormInputDto
    {
        // Bad: public Type GridDefinitionType { get; set; }

        [DisableValidation] // avoids recursive validation and reflection-related exceptions
        [JsonIgnore]        // make sure it's not serialized over HTTP
        public Type GridDefinitionType { get; set; }
    }

• If you extended or wrapped the Forms endpoints, ensure your controller action parameter models do not have self-referencing arrays/objects that the model binder can’t handle.
• Check server logs for exceptions like “Property accessor 'DeclaringMethod' …” or validation errors produced by ABP’s object validator; that indicates you should remove/ignore the problematic field(s) as above.

B) Prevent random re-login when accessing the MVC sub-module from Angular

• You are mixing Angular (OIDC/OAuth2 via implicit/code flow) with MVC sub-application that uses cookie authentication. When rendering the embedded MVC module, if it is on a different origin or uses a different cookie scheme, you can be prompted to log in again.
• Ensure these:
  1. IdentityServer client definitions include both your Angular app and the MVC host of the Forms module as separate clients with proper RedirectUris/PostLogoutRedirectUris and AllowedCorsOrigins.
  2. If the Forms (MVC) is served under your same host/gateway, use the same domain and a consistent cookie configuration. For same-site issues when embedding or cross-origin, set cookie SameSite=None and Secure:

ConfigureApplicationCookie(options =>
     {
         options.Cookie.SameSite = SameSiteMode.None;
         options.Cookie.SecurePolicy = CookieSecurePolicy.Always;
     });

3. If you proxy the MVC forms through a gateway (YARP), make sure the gateway forwards authentication headers and cookies as-is and that CORS/forwarded headers are configured.
4. If the MVC module requires permissions, ensure the current user has the Forms module permissions; otherwise you may see redirects to login due to authorization challenges.

C) Multi-tenancy consistency (tenant login in forms module)

• Ensure the tenant resolution is consistent between Angular and the MVC sub-module:
  • If you use subdomain tenancy or header-based tenancy, configure the gateway to forward X-Tenant or host headers unchanged so that the MVC module can resolve the tenant the same way as Angular.
  • If your Angular app sets the tenant via AbpTenantKey header (X-Tenant-ID or X-Abp-Tenant), ensure:
    • The same header is forwarded to the MVC host through the gateway.
    • The MVC app has the same MultiTenancy options.
  • If tenants are selected via domain (e.g., tenant1.example.com), serve the MVC sub-module from the same subdomain or configure proper ForwardedHeaders to preserve Host:

app.UseForwardedHeaders(new ForwardedHeadersOptions
    {
        ForwardedHeaders = ForwardedHeaders.XForwardedProto | ForwardedHeaders.XForwardedHost
    });

• Double-check the ApplicationUrl, CorsOrigins, and RedirectAllowedUrls for all hosts in appsettings to include your gateway and UI URLs.

D) When hosting SignalR (used by Forms notifications) behind YARP

• If your Forms UI uses SignalR endpoints (e.g., /signalr-hubs/*), add a small middleware in gateway to translate access_token query into Authorization header (WebSockets/ServerSentEvents):

app.Use(async (ctx, next) =>
  {
      var accessToken = ctx.Request.Query["access_token"];
      if (!string.IsNullOrEmpty(accessToken) && ctx.Request.Path.StartsWithSegments("/signalr-hubs"))
      {
          ctx.Request.Headers["Authorization"] = "Bearer " + accessToken;
      }
      await next();
  });

• Ensure YARP routes map:
  • API endpoints: /api/forms/* (or /api/chat/* in similar examples) to the MVC/HttpApi host
  • Hubs: /signalr-hubs/{**everything} to the same host
• Make sure the user has the required permissions for any hub endpoints otherwise 401/403 will occur after negotiate.

E) CORS and Redirects (Angular + MVC)

• In your AuthServer/HttpApiHost appsettings:
  • App:ClientUrl should point to Angular.
  • App:CorsOrigins must include Angular and Gateway origins (comma-separated).
  • App:RedirectAllowedUrls must include Angular and MVC URLs if they do redirects.
• In Angular environment:
  • oAuthConfig.issuer matches your AuthServer URL.
  • apis.default.url points to your gateway or the HttpApi host consistently.

F) Quick verification steps

• Clear caches (Redis/distributed cache) after changing permissions/tenants.
• Verify the current user has the necessary Forms module permissions.
• Confirm the browser’s storage has a valid access token for the Angular app and that the MVC app receives a valid cookie or Authorization header (depending on flow).
• Test in a single-origin setup first (serve Forms MVC under the same domain/port via gateway) to eliminate cross-site cookie issues, then reintroduce separation if needed.
