1. Solution

• What happened
  • The legacy ABP CLI package Volo.Abp.Cli is no longer the actively maintained tool. With ABP v8.2+, a new CLI was introduced and the recommended package is Volo.Abp.Studio.Cli. During today’s nuget.abp.io outage, some tool packages/registration endpoints temporarily returned NotFound, which can surface as “Settings file 'DotnetToolSettings.xml' was not found in the package” when dotnet tool resolves metadata.
• What to do now
  1. Uninstall the old tool (if present): dotnet tool uninstall -g Volo.Abp.Cli
  2. Install the new ABP CLI: dotnet tool install -g Volo.Abp.Studio.Cli This provides the abp command and is the supported path going forward.
  3. If your pipelines or local environment still need the old CLI behavior for older solutions, you can use the new CLI with the --old switch. Examples:
     • Create an older-version solution: abp new Acme.BookStore --version 8.2.0 --old
     • Or explicitly install the old CLI managed by the new one: abp install-old-cli --version 8.0.0
  4. If you still see install/update errors after the outage:
     • Clear any corrupted local NuGet caches: dotnet nuget locals all --clear
     • Ensure nuget.org is reachable and no invalid private feed is forcing resolution to fail (check global NuGet.config in user and machine scope). Remove/disable broken feeds, then retry install.
  5. For CI (Azure DevOps) update the step:
     • Replace: dotnet tool install -g Volo.Abp.Cli
     • With: dotnet tool install -g Volo.Abp.Studio.Cli
     • Optionally add a cache clear before install to avoid stale metadata after the incident: dotnet nuget locals all --clear

1. Solution

• You’re right about DDD: only aggregates should expose invariants and lifecycle of their children. In ABP terms, that usually means:

  • The AggregateRoot has the public API (entity methods) to create/update/remove its child entities.
  • A DomainService (Manager) coordinates rules that don’t naturally fit on a single entity, typically on the aggregate root – not on the child entity itself.

• Current ABP Suite behavior:

  • ABP Suite can generate a Manager (DomainService) per entity, including child entities in a master–detail model. This may allow direct manipulation of the child outside of the aggregate root, which is not ideal from a strict DDD perspective.

• Practical, DDD-friendly approach you can implement today (even with Suite output):

  1. Remove the child’s Manager and ApplicationService (or don’t use them).
  2. Keep a single Manager for the AggregateRoot and add operations for child management there.
  3. Encapsulate child operations within the AggregateRoot entity methods where possible. Use the Manager only when rules cross entity boundaries.
  4. Restrict repositories: avoid injecting IRepository<Child, TKey> into application services. Load the AggregateRoot and modify children via AggregateRoot methods.

• Example Aggregate root with child management methods:

public class Order : AggregateRoot<Guid>
  {
      private readonly List<OrderLine> _lines = new();
      public IReadOnlyCollection<OrderLine> Lines => _lines.AsReadOnly();

      public void AddLine(Guid productId, int quantity, decimal unitPrice)
      {
          if (quantity <= 0) throw new BusinessException("QuantityMustBePositive");
          _lines.Add(new OrderLine(GuidGenerator.Create(), Id, productId, quantity, unitPrice));
      }

      public void UpdateLine(Guid lineId, int quantity, decimal unitPrice)
      {
          var line = _lines.FirstOrDefault(l => l.Id == lineId) ?? throw new BusinessException("LineNotFound");
          line.SetQuantity(quantity);
          line.SetUnitPrice(unitPrice);
      }

      public void RemoveLine(Guid lineId)
      {
          var line = _lines.FirstOrDefault(l => l.Id == lineId) ?? throw new BusinessException("LineNotFound");
          _lines.Remove(line);
      }
  }

  public class OrderManager : DomainService
  {
      // Use when orchestration/rules go beyond a single entity, otherwise prefer entity methods
      public void AddLine(Order order, Guid productId, int quantity, decimal unitPrice)
      {
          // cross-entity checks or policies, then delegate to entity
          order.AddLine(productId, quantity, unitPrice);
      }
  }

Application service using only the aggregate:

public class OrderAppService : ApplicationService
  {
      private readonly IRepository<Order, Guid> _orderRepository;
      private readonly OrderManager _orderManager;

      public OrderAppService(IRepository<Order, Guid> orderRepository, OrderManager orderManager)
      {
          _orderRepository = orderRepository;
          _orderManager = orderManager;
      }

      public async Task AddLineAsync(Guid orderId, Guid productId, int quantity, decimal unitPrice)
      {
          var order = await _orderRepository.GetAsync(orderId);
          _orderManager.AddLine(order, productId, quantity, unitPrice);
          await _orderRepository.UpdateAsync(order, autoSave: true);
      }
  }

• What to request for ABP Suite

  • Add an option in the master–detail wizard: “Generate child DomainService/ApplicationService: Yes/No”.
  • If “No”, generate:
    • No Manager for child entity.
    • Methods for child CRUD inside the master Manager (and optionally inside the AggregateRoot as entity methods).
    • Application service methods that operate on the master aggregate only.
  • If “Yes”, keep current behavior for teams that prefer looser aggregate boundaries.

• Workaround to align current Suite output with DDD:

  • Delete child Manager and AppService classes and their DI registrations.
  • Remove child permissions and routes if generated for direct CRUD.
  • Move child CRUD endpoints under the master AppService (e.g., OrderAppService.AddLineAsync).
  • Ensure repositories for child entities are not injected into external services. Only the master repository should be used.

1. Solution

• Current status and recommendation:

  • ABP entities are commonly defined as public in templates and tools because EF Core, mapping, design-time tooling, and cross-layer usage frequently require public visibility. The official docs and templates do not mandate internal for entities, and many framework base classes (e.g., AuditedEntity) are public.
  • Where stricter encapsulation is desired, you can still keep the domain model internal to the domain layer and expose only DTOs via the application layer. However, making entity classes internal can break EF Core proxies, design-time tools, or cross-assembly usage unless you configure internals visibility.

• Practical options you can apply today:

  1. Keep entities public and encapsulate behavior via aggregates, domain services, and factories. Do not expose entities from the application layer; expose DTOs only.
  2. If you insist on internal domain entities:
     • Place your DbContext and entities in the same domain (or domain EFCore) assembly so EF Core can access the types.
     • If your DbContext is in another assembly, add InternalsVisibleTo for the consuming assembly (and optionally for EF Core proxies):

// In your Domain project (AssemblyInfo.cs or at top of a .cs file)
       using System.Runtime.CompilerServices;

       [assembly: InternalsVisibleTo("YourProjectName.EntityFrameworkCore")]
       [assembly: InternalsVisibleTo("DynamicProxyGenAssembly2")] // if using dynamic proxies (e.g., for mocking)

 - Avoid exposing entities across layers. Continue to expose DTOs in the Application layer and map using ObjectMapper in the same assembly that can see internals.

• About ABP Suite default generation:

  • Suite generates public entities by default. If you want internal, change the access modifier after generation or customize your Suite template to emit internal for entity classes.
  • Be aware that switching to internal may require InternalsVisibleTo as shown above and co-locating DbContext and entity types.

• Related ABP guidance you can leverage:

  • If you need custom entity key patterns or to avoid the conventional Id property and still use repositories and CRUD app services, prefer AbstractKeyCrudAppService over CrudAppService when your entity doesn’t use the default Id pattern:

public class MyAppService :
        AbstractKeyCrudAppService<
            MyEntity,        // entity
            MyEntityDto,     // dto
            MyKeyType,       // key type
            PagedAndSortedResultRequestDto,
            MyCreateUpdateDto
        >, IMyAppService
    {
        public MyAppService(IRepository<MyEntity, MyKeyType> repo) : base(repo) { }
    }

For entities without the conventional Id property, override GetKeys() in your entity:

public class MyEntity : AuditedEntity
    {
        public Guid MyEntityId { get; set; }

        public override object[] GetKeys() => new object[] { MyEntityId };
    }

1. Solution

• Use EF Core ChangeTracker inside a domain event handler (or a SaveChanges interceptor) to read original values. ABP’s EntityUpdatedEventData<T> doesn’t carry old values by design, but you can access EF Core’s OriginalValues and compare.

using Microsoft.EntityFrameworkCore;
  using Microsoft.EntityFrameworkCore.ChangeTracking;
  using Volo.Abp.Domain.Entities.Events;
  using Volo.Abp.EventBus.Local;
  using Volo.Abp.Identity;

  public class IdentityUserUpdatedHandler :
      ILocalEventHandler<EntityUpdatedEventData<IdentityUser>>
  {
      private readonly IDbContextProvider<IIdentityDbContext> _dbContextProvider; // or your unified DbContext provider

      public IdentityUserUpdatedHandler(IDbContextProvider<IIdentityDbContext> dbContextProvider)
      {
          _dbContextProvider = dbContextProvider;
      }

      public async Task HandleEventAsync(EntityUpdatedEventData<IdentityUser> eventData)
      {
          // Ensure we are in the same UoW/DbContext where the change is tracked
          var dbContext = await _dbContextProvider.GetDbContextAsync();

          // Get the tracked Entry for this entity
          var entry = dbContext.Entry(eventData.Entity);
          if (entry.State != EntityState.Modified)
          {
              // Not tracked or not modified in this context
              return;
          }

          // Read original and current values
          var originalName = entry.OriginalValues[nameof(IdentityUser.Name)]?.ToString();
          var currentName  = entry.CurrentValues[nameof(IdentityUser.Name)]?.ToString();

          var originalSurname = entry.OriginalValues[nameof(IdentityUser.Surname)]?.ToString();
          var currentSurname  = entry.CurrentValues[nameof(IdentityUser.Surname)]?.ToString();

          var nameChanged = !string.Equals(originalName, currentName, StringComparison.Ordinal);
          var surnameChanged = !string.Equals(originalSurname, currentSurname, StringComparison.Ordinal);

          if (nameChanged || surnameChanged)
          {
              // Your logic here (publish another event, call a service, etc.)
          }
      }
  }

Notes:

• Inject the IDbContextProvider for the DbContext that tracks IdentityUser (e.g., your unified AppDbContext if you call builder.ConfigureIdentity()).

• This handler must run within the same Unit of Work as the update so the Entry has OriginalValues. ABP’s auto entity events are published in the same UoW as of v5+, so this works when your update happens via repositories/UoW.

• Alternative: EF Core SaveChanges interceptor If you prefer not to rely on the local event to get original values, you can implement an interceptor that always has access to ChangeTracker before saving:

using Microsoft.EntityFrameworkCore;
  using Microsoft.EntityFrameworkCore.Diagnostics;
  using Volo.Abp.Identity;

  public class UserNameChangeInterceptor : SaveChangesInterceptor
  {
      public override InterceptionResult<int> SavingChanges(DbContextEventData eventData, InterceptionResult<int> result)
      {
          var context = eventData.Context;
          if (context == null) return base.SavingChanges(eventData, result);

          foreach (var entry in context.ChangeTracker.Entries<IdentityUser>().Where(e => e.State == EntityState.Modified))
          {
              var originalName = entry.OriginalValues[nameof(IdentityUser.Name)]?.ToString();
              var currentName  = entry.CurrentValues[nameof(IdentityUser.Name)]?.ToString();
              var originalSurname = entry.OriginalValues[nameof(IdentityUser.Surname)]?.ToString();
              var currentSurname  = entry.CurrentValues[nameof(IdentityUser.Surname)]?.ToString();

              if (!string.Equals(originalName, currentName, StringComparison.Ordinal) ||
                  !string.Equals(originalSurname, currentSurname, StringComparison.Ordinal))
              {
                  // Your logic here
              }
          }

          return base.SavingChanges(eventData, result);
      }
  }

Register the interceptor in your DbContextOptions during module ConfigureServices.

• Why not use audit logs? ABP’s audit logging can record entity change sets including old/new property values, but it’s intended for logging. If you need runtime logic when Name/Surname changes, the ChangeTracker approach is the correct, supported way.

1. Solution

• Root cause: When using the distributed event bus (RabbitMQ), the handler runs in a background consumer without an HTTP scope, so there is no ambient tenant set automatically. IdentityUserCreatedEto contains TenantId; you must set the tenant context for the duration of your handler to resolve tenant-scoped services/settings correctly.

• Quick fix (wrap the handler body in ICurrentTenant.Change):

using Volo.Abp.MultiTenancy;

  public class AccountIdentityUserCreatedEventHandler :
      IDistributedEventHandler<IdentityUserCreatedEto>,
      ITransientDependency
  {
      protected IdentityUserManager UserManager { get; }
      protected IAccountEmailer AccountEmailer { get; }
      protected ISettingProvider SettingProvider { get; }
      protected ICurrentTenant CurrentTenant { get; }

      public AccountIdentityUserCreatedEventHandler(
          IdentityUserManager userManager,
          IAccountEmailer accountEmailer,
          ISettingProvider settingProvider,
          ICurrentTenant currentTenant)
      {
          UserManager = userManager;
          AccountEmailer = accountEmailer;
          SettingProvider = settingProvider;
          CurrentTenant = currentTenant;
      }

      public async Task HandleEventAsync(IdentityUserCreatedEto eventData)
      {
          using (CurrentTenant.Change(eventData.TenantId))
          {
              if (eventData.Properties["SendConfirmationEmail"] == true.ToString().ToUpper() &&
                  await SettingProvider.IsTrueAsync(IdentitySettingNames.SignIn.RequireConfirmedEmail))
              {
                  var user = await UserManager.GetByIdAsync(eventData.Id);
                  var confirmationToken = await UserManager.GenerateEmailConfirmationTokenAsync(user);
                  await AccountEmailer.SendEmailConfirmationLinkAsync(
                      user,
                      confirmationToken,
                      eventData.Properties.GetOrDefault("AppName") ?? "MVC"
                  );
              }
          }
      }
  }

• This ensures SettingProvider (and any tenant-scoped logic like repositories, feature checks, etc.) work under the correct tenant.

• If you need host-level settings for some reason, wrap only the required code block with Change(null).

• Notes:

  • In-memory distributed bus handlers run in-process and may inherit the ambient tenant from the publisher scope; RabbitMQ consumers don’t, so you must explicitly set it.
  • IdentityUserCreatedEto includes TenantId; rely on it to set the tenant scope before accessing tenant-scoped services.

1. Solution You have three reliable ways to run custom logic specifically when an admin updates a user via PUT api/identity/users/{id} and also compare old vs. new values (e.g., Surname changes):

A) Override the IdentityUserAppService UpdateAsync (best if you only need to affect this specific endpoint)

• Create your own application service deriving from IdentityUserAppService and replace the service via dependency injection.
• Read the existing user first, keep a snapshot, call base.UpdateAsync (or replicate the logic), then compare and run your custom code.

using System.Threading.Tasks;
using Volo.Abp.Application.Services;
using Volo.Abp.DependencyInjection;
using Volo.Abp.Identity;
using Volo.Abp.Users;

[Dependency(ReplaceServices = true)]
public class MyIdentityUserAppService : IdentityUserAppService
{
    public MyIdentityUserAppService(
        IdentityUserManager userManager,
        IIdentityUserRepository userRepository,
        IIdentityRoleRepository roleRepository)
        : base(userManager, userRepository, roleRepository)
    {
    }

    public override async Task<IdentityUserDto> UpdateAsync(Guid id, IdentityUserUpdateDto input)
    {
        // Load current (old) values
        var oldUser = await UserRepository.GetAsync(id);
        var oldSurname = oldUser.Surname;
        var oldEmail = oldUser.Email;

        // Call the default update pipeline
        var result = await base.UpdateAsync(id, input);

        // Compare with new values
        var newSurname = result.Surname;
        var newEmail = result.Email;

        if (!string.Equals(oldSurname, newSurname, StringComparison.Ordinal))
        {
            // Your logic when surname changed
            // e.g., publish a distributed event, call an external service, etc.
        }

        if (!string.Equals(oldEmail, newEmail, StringComparison.OrdinalIgnoreCase))
        {
            // Your logic when email changed
        }

        return result;
    }
}

• Registering with [Dependency(ReplaceServices = true)] ensures your app service is used for the /api/identity/users/{id} endpoint. This gives you precise control and easy old/new comparison.

B) Override/extend IdentityUserManager (when you want to enforce logic at the domain level)

• If you need invariant business rules regardless of which app service updates users, customize IdentityUserManager, intercept setters or update methods and implement comparisons there. This is more invasive but centralizes the logic. In ABP 8, IdentityUserManager includes IDistributedEventBus injection to publish events on email/username changes.

C) Use extension to the admin UI and profile UI (if you need UI-driven logic) – not required for backend comparison but helpful when you also need to surface or control fields. For DTO extra properties to flow correctly through built-in services (like profile), ensure module extension mappings are applied to the related DTOs:

public class MyModule : AbpModule
{
    private static readonly OneTimeRunner OneTimeRunner = new OneTimeRunner();

    public override void PostConfigureServices(ServiceConfigurationContext context)
    {
        OneTimeRunner.Run(() =>
        {
            ModuleExtensionConfigurationHelper.ApplyEntityConfigurationToApi(
                IdentityModuleExtensionConsts.ModuleName,
                IdentityModuleExtensionConsts.EntityNames.User,
                getApiTypes: new[] { typeof(IdentityUserDto), typeof(ProfileDto) },
                createApiTypes: new[] { typeof(IdentityUserCreateDto) },
                updateApiTypes: new[] { typeof(IdentityUserUpdateDto), typeof(UpdateProfileDto) }
            );
        });
    }
}

Notes about “events get called a lot” and comparing old/new data:

• Domain/Event handlers like EntityUpdated are broad and can fire from different code paths. If you only care about the admin PUT endpoint, approach A is the most targeted.
• If you still prefer events, you can load the previous state before the operation in your app service, attach it to the event payload you publish, or include both old and new in a custom distributed event so handlers can compare safely.
• For specific changes (like email/username), ABP 8 added distributed events from IdentityUserManager so downstream code can know old values. For other fields like Surname, do the old/new comparison yourself in UpdateAsync as shown.

1. Solution The 404 on IIS for module Razor Pages typically means the pages are not discovered at runtime on the server. In ABP modular monoliths this happens when the module’s Razor Pages and embedded resources aren’t registered or published correctly, or when middleware order misses virtual files.

Apply the checklist below and republish:

• Ensure each module’s Web module depends on AbpAspNetCoreMvcModule and registers embedded Razor Pages:

[DependsOn(
      typeof(AbpAspNetCoreMvcModule)
      // + other dependencies...
  )]
  public class LmsWebModule : AbpModule
  {
      public override void ConfigureServices(ServiceConfigurationContext context)
      {
          // Allow ABP to find embedded Razor pages of this module
          Configure<AbpVirtualFileSystemOptions>(options =>
          {
              options.FileSets.AddEmbedded<LmsWebModule>();
          });

          context.Services
              .AddRazorPages()
              .AddApplicationPart(typeof(LmsWebModule).Assembly);
      }

      public override void OnApplicationInitialization(ApplicationInitializationContext context)
      {
          var app = context.GetApplicationBuilder();
          var env = context.GetEnvironment();

          if (env.IsDevelopment())
          {
              app.UseDeveloperExceptionPage();
          }

          app.UseStaticFiles();
          app.UseRouting();

          app.UseAuthentication();
          app.UseAuthorization();

          // IMPORTANT for ABP virtual/embedded files (including Razor pages/views)
          app.UseAbp(); // ensures UseAbpVirtualFiles inside the pipeline

          app.UseConfiguredEndpoints(); // maps Razor Pages
      }
  }

• In the main web host module, also ensure AddRazorPages().AddApplicationPart(...) for each module that contains pages (or rely on conventional discovery by referencing the module assembly).
• In ConfigureServices of the main web host, if you use Razor Class Libraries, you can also add:

services.AddControllersWithViews()
            .AddApplicationPart(typeof(LmsWebModule).Assembly)
            .AddControllersAsServices();
    services.AddRazorPages()
            .AddApplicationPart(typeof(LmsWebModule).Assembly);

• Make sure the module assemblies that contain the Razor Pages are referenced by the host web project so they’re copied to publish output. In the host .csproj:

<ItemGroup>
    <ProjectReference Include="..\..\modules\Lms\src\Lms.Web\Lms.Web.csproj" />
    <!-- repeat for other modules that have Razor Pages -->
  </ItemGroup>

If you pack modules as NuGet packages, ensure the package is referenced by the host and contains the compiled Razor views (RCL).

• Verify wwwroot and ABP virtual files are served in IIS:
  • In the host’s module initialization:
    • app.UseStaticFiles();
    • app.MapAbpStaticAssets(); (ABP 9+ web apps) or app.UseAbp() which registers UseAbpVirtualFiles.
  • Confirm that the publish includes static content:

<ItemGroup>
      <Content Include="wwwroot\**\*">
        <CopyToPublishDirectory>Always</CopyToPublishDirectory>
      </Content>
    </ItemGroup>

• Remove IIS WebDAV for non-GET verbs if you also see 405 on POST/PUT/DELETE (commonly blocks form posts or antiforgery flows): Web.config snippet under system.webServer:

<modules>
    <remove name="WebDAVModule" />

• Publishing notes:
  • Use dotnet publish for Release and deploy the publish folder to IIS. Ensure all module assemblies are present in the publish output.
  • If you see “multiple publish output files with same relative path” for Razor Pages across modules (e.g., duplicate Pages/_ViewImports.cshtml), either rename conflicting files or set:

<PropertyGroup>
      <ErrorOnDuplicatePublishOutputFiles>false</ErrorOnDuplicatePublishOutputFiles>
    </PropertyGroup>

in the host web project as a workaround.

• Middleware order sanity check (host application):

app.UseCorrelationId();
  app.UseStaticFiles();
  app.UseRouting();
  app.UseAuthentication();
  app.UseAuthorization();

  app.UseAbp(); // registers ABP middleware incl. virtual files and localization, etc.

  app.UseConfiguredEndpoints(); // ABP maps controllers and Razor Pages

• Diagnose on server:
  • Hitting your check-razor-pages endpoint returned empty because PageActionDescriptors weren’t discovered. After applying AddRazorPages().AddApplicationPart(moduleAsm) and ensuring assemblies are present, re-check: you should see ViewEnginePath/RelativePath entries and non-empty count. Also verify that AttributeRouteInfo can be null for Razor Pages; rely on ViewEnginePath/RouteValues instead of RouteTemplate.

If these steps are applied, the same module Razor Pages that work locally will be discovered and served on IIS.

1. Solution Your logs show the menu items are protected by permissions but your logged-in user doesn’t have them granted. In ABP, menu items are commonly added with requiredPermissionName. If the user lacks that permission, the item is hidden and you’ll see “Authorization failed … PermissionRequirement: X” in logs, as you have (CmsKit.SettingManagement, CmsKit.PageFeedback.SettingManagement, Forms.Form).

Fix it by granting the required permissions to the user/role, or by removing the permission requirements from menu items if you want them always visible.

Step-by-step (recommended)

• Ensure Permission Management is reachable in your app (it is included by default in the standard app templates).
• Log in as admin (host or the related tenant).
• Open Administration -> Identity -> Roles -> edit the Admin role -> Permissions.
• Search and grant the missing permissions you see in the logs:
  • CmsKit.SettingManagement
  • CmsKit.PageFeedback.SettingManagement
  • Forms.Form (and other Forms.* if needed)
• Save, then log out and log back in (or refresh) to reload claims/permissions.
• If you use multi-tenancy, grant them on the correct side:
  • Host-side admin: switch to Host and grant on host.
  • Tenant-side admin: switch to the specific tenant and grant on tenant.
• In microservice apps, ensure the Web (UI) application is calling the correct Auth/Identity endpoints and the Permission Management module is installed/enabled in the same tenant/side.

Optional checks

• Verify menu contributors use requiredPermissionName matching those permissions. Example:

context.Menu.AddItem(
      new ApplicationMenuItem(
          "CmsKit.Settings",
          L["Menu:CmsSettings"],
          url: "/CmsKit/Settings",
          icon: "fa fa-cog",
          requiredPermissionName: CmsKitPermissions.SettingManagement
      )
  );

If requiredPermissionName is set, the user must have that permission.

• If you seed permissions by code, confirm the seeder actually runs for the current tenant/side and grants these permissions to the Admin role:

await _permissionManager.SetForRoleAsync("admin", CmsKitPermissions.SettingManagement, true);
  await _permissionManager.SetForRoleAsync("admin", CmsKitPermissions.PageFeedback.SettingManagement, true);
  await _permissionManager.SetForRoleAsync("admin", "Forms.Form", true);

• If you recently enabled modules (CmsKit, Forms), run DbMigrator for new permissions and ensure their packages/modules are added to the Web and HttpApi services, and that permission definitions appear under Permission Management UI.
• Clear/refresh caches:
  • Redis/Dist cache if used.
  • Sign out/in to refresh the authentication ticket.

1. Solution

• Root cause

  • Angular’s PermissionService reads grantedPolicies from the Application Configuration endpoint (/api/abp/application-configuration). On the backend, this endpoint builds grantedPolicies using IPermissionChecker.IsGrantedAsync(string[] names) to evaluate multiple permissions at once for efficiency.
  • In current ABP, the single-permission check and multi-permission check use different resolution flows: for a single permission, all registered PermissionValueProviders participate and any Prohibited overrides Granted (as documented). For multiple permissions, the evaluation short-circuits by returning the first non-Undefined result from the providers, so provider registration order affects the outcome. If your custom PermissionValueProvider that returns Prohibited is registered after a provider that returns Granted, the multi-permission path may never “see” your Prohibited result. This leads to grantedPolicies including PermissionA even though your backend AuthorizationService.CheckAsync("PermissionA") fails (because Check/IsGranted for a single permission considers all providers and respects Prohibited-overrides-Granted).

• How to get consistent results (server and Angular)

  1. Ensure your custom provider runs before the built-ins when building grantedPolicies
     • Register your provider at the beginning, so its Prohibited can take precedence in the multi-permission path used by application configuration.
     • Example:

Configure<PermissionOptions>(options =>
       {
           // Insert at the beginning to ensure it’s checked first
           options.ValueProviders.Insert(0, typeof(MyCustomPermissionValueProvider));
           // If you previously used Add(), it appends to the end — change it to Insert(0, ...)
       });

2. Prefer single-permission checks when building grantedPolicies
   • If you have overridden the AbpApplicationConfigurationAppService or produce your own grantedPolicies map, ensure you use IPermissionChecker.IsGrantedAsync(string name) per permission instead of the overload that accepts a list. That guarantees the “all providers participate, Prohibited overrides Granted” behavior for each permission:

// Pseudocode inside your configuration builder
       foreach (var permission in permissionDefinitionManager.GetPermissions())
       {
           var granted = await permissionChecker.IsGrantedAsync(permission.Name);
           if (granted)
           {
               dto.Auth.GrantedPolicies[permission.Name] = true;
           }
       }

 - If you haven’t overridden anything, fixing provider order (step 1) is typically sufficient.

3. If you must use the multi-permission overload for performance, enforce provider precedence
   • Keep using IsGrantedAsync(string[] names) but make sure your custom provider is ordered first (Insert(0, ...)). This ensures the first non-Undefined is your Prohibited result for any permissions it handles.
4. Double-check your provider logic
   • Return PermissionGrantResult.Prohibited only for the permissions you truly want to block.
   • Return PermissionGrantResult.Undefined for everything else so other providers can participate (role, user, client, etc.).

• Verification checklist
  • Register your custom provider via Insert(0, typeof(MyCustomPermissionValueProvider)).
  • Confirm /api/abp/application-configuration returns auth.grantedPolicies without the prohibited permission.
  • Confirm Angular’s this.permissionService.getGrantedPolicy('PermissionA') returns false.
  • Confirm backend AuthorizationService.CheckAsync("PermissionA") throws as expected.

1. Solution

• What exit code -42 means in ABP Studio

  • In ABP Studio, “exited with code: -42” indicates the target app (e.g., HttpApi.Host, Web.Public) terminated unexpectedly soon after start. It’s typically caused by an unhandled startup failure (ports, configuration, missing env/deps), not by ABP Framework itself. The Solution Runner then keeps attempting restarts.

• Likely causes from your log and setup

  • HTTPS port conflict or reservation: Studio probes health endpoints at 44302/44383 and the UI at 44382. If these ports are blocked, reserved by HTTP.SYS, or fall into Windows excluded port ranges, the app can start then crash.
  • Certificate/HTTPS binding issues: Kestrel can fail when the dev cert is missing/untrusted on new machines.
  • PostgreSQL connectivity: With Separate Tenant Schema + initial migration run, any wrong connection string or unreachable DB can kill the host at startup.
  • NuGet feeds/tooling: If global NuGet.config forces an unreachable private source for tools or packages, builds can succeed partially but runtime may fail later during dynamic restore.
  • Environment differences between machines: Missing .NET SDKs required by the solution, or prereqs not present.

• Fix checklist (perform on every affected machine)

  1. Verify .NET SDKs
     • Install the SDKs targeted by your solution (check global.json and csproj TargetFramework). Ensure dotnet --info shows them.
  2. Clean/restore/build once outside Studio
     • From the solution folder:
       • dotnet clean
       • dotnet restore
       • dotnet build -c Debug
     • If build fails, fix errors first.
  3. Ensure HTTPS dev certificate is installed and trusted
     • dotnet dev-certs https --clean
     • dotnet dev-certs https --trust
  4. Free or remap ports
     • Check excluded/occupied ports:
       • netsh interface ipv4 show excludedportrange protocol=TCP
       • netsh http show urlacl
       • netstat -ano | findstr :44382
     • If 44302/44382/44383 are in excluded ranges or used, change ports:
       • In each app’s appsettings.json (or launchSettings.json), change Kestrel:Endpoints:Https:Url (and Health endpoints) to free ports, or in ABP Studio Runner profile set different ports, then run again.
  5. Trust local hostnames
     • Make sure you browse the exact HTTPS URLs Studio opens. If the browser prompts for cert trust, accept it.
  6. Verify PostgreSQL connectivity
     • Confirm the default connection string in your HttpApi.Host appsettings.* points to a reachable PostgreSQL instance with correct credentials.
     • Test with psql or a client using the same host, port, db, user, password.
     • If you use separate schemas per tenant, ensure the database exists and the migrator was executed successfully.
  7. Re-run the DbMigrator
     • From src/OPUSNova.DbMigrator:
       • dotnet run
     • Fix any migration/connection errors it shows.
  8. Check global NuGet config for unreachable private feeds
     • If you have a company NuGet feed configured globally that is not reachable on some machines, it can break tool/package restore. Remove or disable it temporarily in %AppData%\NuGet\NuGet.Config or related config files and keep nuget.org active.
     • This exact issue was reported and fixed by removing a stale private feed from NuGet.Config.
  9. Start projects manually to see first exception
     • Run OPUSNova.HttpApi.Host from command line:
       • dotnet run
     • Observe the first thrown exception/stack trace in the console; it often reveals the exact root cause that Studio abstracts as exit code -42.
  10. ABP Studio prerequisites
  • Ensure ABP Studio CLI is installed and can run:
    • abp cli version
  • If it fails due to NuGet source issues, fix NuGet.Config as in step 8.

• Notes for Blazor WASM + Public Website profile

  • The Blazor (WASM) and Public site rely on the HTTP API host being up. If the host crashes (-42), both health checks will fail and Studio restarts them. Fixing the host’s startup error usually resolves the rest.
