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...”:

                              // IsDeleted = 0
                              return new SqlBinaryExpression(
                                  ExpressionType.Equal,
                                  isDeleted,

                          // no WHERE fragment when disabled
                          return new SqlConstantExpression(Expression.Constant(true), boolParam.TypeMapping);
                      });
              }

              expression = expression == null

          }

          // IMultiTenant

                  !MultiTenantEnabled || EF.Property<Guid?>(e, "TenantId") == CurrentTenant.Id;

              if (UseDbFunction())
              {
                  tenantFilter = e => TenantUdf(((IMultiTenant)e).TenantId, CurrentTenant.Id);

                  var current = this.GetService<AbpEfCoreCurrentDbContext>();

                  modelBuilder.HasDbFunction(typeof(MyProjectDbContext).GetMethod(nameof(TenantUdf))!)
                      .HasTranslation(args =>
                      {
                          var entityTenantId = args[0];
                          var currentTenantId = args[1];

                          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.

• 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.

1. Solution

• ABP localizes exception messages by mapping exception “code namespaces” to a localization resource. Configure this once and all infrastructure errors that have codes (like authorization/validation) will be shown in the current UI culture.
• Add a resource for your app (Domain.Shared) and map the ABP namespaces that you want to localize.

Example: Map authorization/validation/identity namespaces to your resource and provide translations.

csharp // Domain.Shared module [DependsOn( typeof(AbpExceptionHandlingModule), typeof(AbpValidationModule), typeof(AbpAuthorizationModule), typeof(AbpIdentityDomainSharedModule) )] public class MyProjectDomainSharedModule : AbpModule { public override void ConfigureServices(ServiceConfigurationContext context) { Configure<AbpLocalizationOptions>(options => { options.Resources .Add<MyProjectResource>("en") .AddVirtualJson("/Localization/MyProject"); });

    Configure<AbpExceptionLocalizationOptions>(options =>
    {
        // Map exception code namespaces to your resource
        options.MapCodeNamespace("Volo.Abp.Authorization", typeof(MyProjectResource));
        options.MapCodeNamespace("Volo.Abp.Validation", typeof(MyProjectResource));
        options.MapCodeNamespace("Volo.Abp.Identity", typeof(MyProjectResource));
        // add more if needed
    });
}

}

• Create localization JSON files that contain the exception texts for the mapped namespaces.
  • Place under MyProject.Domain.Shared/Localization/MyProject/
  • Example en.json and tr.json (Turkish). Include keys used by ABP’s infrastructure. For “Forbidden” (authorization), ABP uses well-known codes and messages; provide localized texts.

en.json { "culture": "en", "texts": { "Volo.Abp.Authorization:DefaultErrorMessage": "The user represented by the token is not allowed to perform the requested action.", "Volo.Abp.Authorization:Forbidden": "Forbidden" } }

tr.json { "culture": "tr", "texts": { "Volo.Abp.Authorization:DefaultErrorMessage": "Belirteçle temsil edilen kullanıcı bu işlemi yapmaya yetkili değil.", "Volo.Abp.Authorization:Forbidden": "Yasak" } }

Notes:

• The exact keys used by ABP for authorization exceptions are tied to the exception code namespace Volo.Abp.Authorization. After mapping, any ABP-generated authorization error (like forbidden) is localized via your resource. If a specific key is missing, ABP falls back to the default message; add keys you need.
• Ensure your MVC UI sets and switches CurrentUICulture (ABP does this via the language selector/cookie). Then the modal error message will automatically be shown in the current language.

Optional: Customize the displayed title/text shape for MVC UI

• ABP MVC shows RemoteServiceErrorInfo (ProblemDetails) in a modal. To override formatting, implement IExceptionToErrorInfoConverter or subscribe to AbpExceptionEvent to adjust message keys, but in most cases mapping and providing translations is sufficient.

1. Solution Given your configuration:

• ISaveStaticPermissionsToDatabase = true: ABP will persist statically-defined permissions (from your PermissionDefinitionProvider classes) into the PermissionDefinition records on startup. This avoids runtime reflection lookups and enables querying/managing those definitions via the Permission Management module.
• IsDynamicPermissionStoreEnabled = false: Disables custom/dynamic permission store providers. ABP will use the built‑in permission store (cached + DB-backed). This can reduce complexity and unexpected provider hits.

Addressing your points:

A) “If we refer to other Application layer Contracts, lead to static access storage”

• Best practice: Place PermissionDefinitionProvider in the Application.Contracts layer of the module that owns those permissions. Other modules can reference the Contracts assembly to access the permission name constants without introducing runtime dependency cycles. This is the standard ABP approach and does not cause runtime permission “static access storage” risks by itself. It’s the recommended source of truth for permission names and localization.

B) “Additional load to other Application permissions”

• With ISaveStaticPermissionsToDatabase = true, permission definitions are saved once (on startup/first run), then served via cache and DB. Combined with IsDynamicPermissionStoreEnabled = false, ABP will not query additional dynamic providers. This typically reduces load, not increase it. For performance:
  • Ensure distributed cache (e.g., Redis) is properly configured in production.
  • Keep permission grouping/nesting balanced; a very large number of permissions can increase the first application-configuration call cost.
  • Avoid querying permission grants in your overridden AbpApplicationConfigurationAppService.GetAsync beyond what ABP already returns; if you must, cache your extra computations.

C) “Move XXXPermissionDefinitionProvider to Application layer”

• Correct location is Application.Contracts (not Application). ABP docs and samples define PermissionDefinitionProvider in the *.Application.Contracts project so UI/API layers and seed/migrator can reference it.
• Seeders (e.g., DbMigrator) should reference Application.Contracts to access permission names and definitions when seeding role grants.

D) Recommended setup

• Keep PermissionDefinitionProvider in MyModule.Application.Contracts.
• Keep your configuration as-is if you don’t need dynamic providers:

Configure<PermissionManagementOptions>(options =>
  {
      options.ISaveStaticPermissionsToDatabase = true;
      options.IsDynamicPermissionStoreEnabled = false;
  });

• If you seed role permissions, implement a data seed contributor that uses IPermissionManager / IPermissionDataSeeder or similar to grant permissions to roles/users at migration time. Ensure the DbMigrator references Application.Contracts so it sees the definitions.

E) Troubleshooting tips

• If the first /api/abp/application-configuration becomes heavy:
  • Remove custom extra DB scans from overridden GetAsync or wrap them with distributed cache keyed by user/tenant.
  • Rely on ABP’s built-in permission list in ApplicationConfigurationDto unless you must enrich; then precompute and cache module maps.
  • Verify Redis connection and ABP DistributedCache options (timeouts) to avoid slow cache misses.

1. Solution

• Why DbMigrator didn’t create the audit DB

  • DbMigrator only runs migrations for DbContexts that:
    • are registered in the solution and
    • have migrations compiled into the assembly and
    • have a configured provider/connection string.
  • If AbpAuditLoggingDbContext has no migrations in your solution, DbMigrator won’t create the database.

• Fix step-by-step

  1. Ensure EF Core provider/config for AbpAuditLoggingDbContext

[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 =>
          {
              // Global default or per-context config
              options.UseSqlServer();

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

2. Provide a connection string named AbpAuditLogging (or it will fall back to Default)

• appsettings.json (DbMigrator and all hosts that write audit logs):

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

3. Add migrations for AbpAuditLoggingDbContext into your migrations project

• Add the AbpAuditLogging.EntityFrameworkCore package reference to the project where you keep migrations (commonly the EFCore or DbMigrator project references it).

• Make sure the project builds and can resolve the context at design-time. Typically you either:

  • run the dotnet ef command in the project that contains the DbContext OR
  • create a design-time factory.

• Example design-time factory (only for migration generation):

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: false)
              .AddEnvironmentVariables()
              .Build();

          var builder = new DbContextOptionsBuilder<AbpAuditLoggingDbContext>()
              .UseSqlServer(configuration.GetConnectionString("AbpAuditLogging"));

          return new AbpAuditLoggingDbContext(builder.Options);
      }
  }

• Generate the migrations (run in the project that references Volo.Abp.AuditLogging.EntityFrameworkCore and contains the factory above):

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

Notes:

• Use the full type name if the short name isn’t found.
• Ensure the startup project specified by --startup-project (if needed) can load your module configuration and has the connection strings.

4. Run DbMigrator once migrations exist

• DbMigrator, by default, discovers and runs all registered IDbSchemaMigrator implementations (including AuditLogging’s). With the migrations compiled, it will create the AuditDb and apply its migrations automatically:

dotnet run --project src/YourApp.DbMigrator

5. Common pitfalls causing “No DbContext named 'AbpAuditLoggingDbContext' was found”

• You ran dotnet ef in a project that does not reference Volo.Abp.AuditLogging.EntityFrameworkCore.
• The context is not discoverable at design-time. Add a design-time factory (shown above), or set --startup-project and run the command from the EFCore project that references the module.
• You used the short context name; prefer the fully-qualified name: Volo.Abp.AuditLogging.EntityFrameworkCore.AbpAuditLoggingDbContext

6. Ensure auditing is enabled and middleware added (for actual runtime logging)

Configure<AbpAuditingOptions>(options =>
  {
      options.IsEnabled = true;
      options.EntityHistorySelectors.AddAllEntities();
  });

  public override void OnApplicationInitialization(ApplicationInitializationContext context)
  {
      var app = context.GetApplicationBuilder();
      app.UseAuditing();
  }

• Summary
  • Add the AuditLogging EFCore module and provider config.
  • Add/use the AbpAuditLogging connection string (or it falls back to Default).
  • Create migrations for AbpAuditLoggingDbContext (design-time factory often required).
  • Run DbMigrator; it will then create and migrate the separate audit DB.

1. Solution

• Short answer
  • Use the abp-modal options input to pass ng-bootstrap’s NgbModalOptions and set a unique windowClass for that one modal. Then, add a global style targeting that specific windowClass to control the width. This changes only that modal.
• How to do it
  1. Set a unique windowClass via options on your abp-modal

<abp-modal
    [(visible)]="isOpen"
    [options]="{ windowClass: 'my-wide-modal', size: 'xl' }"
  >
    <ng-template #abpHeader>My Wide Editor</ng-template>
    <ng-template #abpBody> ... complex content ... </ng-template>
    <ng-template #abpFooter>
      <abp-button (click)="isOpen = false">Close</abp-button>
    </ng-template>
  </abp-modal>

Notes:

• options is forwarded to NgbModal.open(...) internally, so you can use any NgbModalOptions, including windowClass, size, centered, scrollable, keyboard, etc.
• size can be set here as well, but for a near-full-width modal you’ll typically override width via CSS.

2. Add a global style that targets only that modal window Put this in styles.scss (or global theme stylesheet):

ngb-modal-window.my-wide-modal .modal-dialog {
    max-width: 90vw !important; /* or a fixed px width */
    width: 90vw;                /* ensure it expands */
    margin: 1.5rem auto;        /* optional: adjust centering/margins */
  }

  /* Optionally control body height/scrolling if needed */
  ngb-modal-window.my-wide-modal .modal-content {
    height: calc(100vh - 3rem);
  }

Why global? NgbModal renders outside the component tree, so ViewEncapsulation styles won’t reach it. A unique windowClass ensures the rule applies only to that single modal, not globally.

• About dialogClass/modalClass inputs

  • abp-modal does not expose dialogClass or modalClass inputs; hence the Angular template error you saw. Use options.windowClass instead.

• Is passing custom NgbModal options supported?

  • Yes. abp-modal exposes an options input of type NgbModalOptions and spreads it into NgbModal.open(...). You can set windowClass, size, centered, scrollable, keyboard, etc., and they will be respected.

• If you prefer a CSS-only approach without options

  • You can still set the unique class via options (recommended), then handle all sizing purely in CSS as shown above. Avoid styling only by Bootstrap’s modal-xl class globally, since that affects all modals.

• Recommended alternative for very complex editors

  • If the content requires near full-page experience, consider:
    • Routing to a dedicated page for the editor (best UX for heavy forms/tables).
    • Or, still use abp-modal with windowClass and add responsive CSS as above.
