• In the latest ABP Studio, Angular UI now defaults to the standalone component structure, but module-based (NgModule) DDD modules are still supported for backwards compatibility. When adding a new DDD module, you can select the user interface type (including Angular) as before.

• The process is:

  1. Right-click the solution root in ABP Studio.
  2. Select Add > New Module > DDD Module.
  3. In the dialog, choose "Angular" as the UI option.
  4. Proceed with the rest of the wizard (database provider, etc.).

• If you want to use the previous module-based structure instead of the new standalone approach, ABP Studio and ABP Schematics still support both. When generating a library or module, you will be prompted to select the template type: "module" (classic NgModule) or "standalone" (new Angular structure). Choose "module" to keep the old behavior.

• Both approaches are maintained for compatibility, so you can continue to add Angular DDD modules as before by selecting the appropriate template type during module creation.

When creating a new solution in ABP Studio, the solution name you provide in the wizard should be used as the actual solution name. The behavior where ABP Studio replaces your chosen name with "AbpSolution1", "AbpSolution2", etc., is not expected and does not align with the documented workflow.

This issue may be related to a bug in the ABP Studio version distributed via the Microsoft Store. The official documentation and release notes do not mention this as standard or intended behavior. The ABP CLI, as you observed, correctly uses the provided solution name.

Recommended Actions:

1. Ensure you are using the latest version of ABP Studio. You can check for updates within the application via Help -> Check for Updates or download the latest version directly from the official site: https://abp.io/studio
2. If the problem persists with the latest version, consider downloading ABP Studio directly from the official ABP website instead of the Microsoft Store, as there may be differences in distribution or update timing.
3. If the issue continues, report it as a bug to the ABP team via their GitHub issues page or support channels, providing details about your environment and steps to reproduce.

For now, using the ABP CLI is a valid workaround, as it respects your provided solution name.

Thank you for the detailed analysis and proposed solutions regarding the IdentityLinkUser query performance issue in ABP Framework 9.2.1. Your assessment is accurate and aligns with previously reported issues, including:

• Excessive parameter generation in the SQL query by IdentityLinkUserRepository.GetListAsync(), especially with includeIndirect: true.
• The resulting O(n²) parameter growth, which quickly approaches SQL Server's 2100 parameter limit and causes severe performance degradation or outright query failure as the number of linked users increases.

Your workaround using includeIndirect: false and batch fetching is a valid mitigation, but as you noted, it does not address the underlying inefficiency in the repository implementation.

Based on validated sources and the current state of the ABP Framework:

• This issue has been reported and discussed in detail in the following support threads:

  • [Linked Accounts - The loading time of the modal is too long (Question #9859)](https://abp.io/support/questions/9859)
  • [ABP EF Core horribly slow with 2k related entities (Question #9631)](https://abp.io/support/questions/9631)
  • [Linked Account modal is too slow (Question #4568)](https://abp.io/support/questions/4568)

• The root cause is the recursive, exclusion-based query pattern in the repository, which is not scalable for large numbers of linked users.

• As of ABP 9.2.1 (and up to 9.2.3), there is no built-in support for recursive CTEs or temp table-based solutions in the IdentityLinkUserRepository. The current implementation still relies on iterative exclusion, leading to parameter explosion.

• Your proposed solution using a recursive CTE is the recommended approach for SQL Server and would resolve the parameter limit and performance issues. However, this is not yet implemented in the official ABP modules.

• The ABP team has acknowledged the problem in the referenced support threads, and partial improvements (such as GetListByIdsAsync) have been made, but a full repository-level fix (e.g., CTE-based querying) is not yet available.

Recommended Actions:

1. Continue using your current workaround (includeIndirect: false and batch fetching) to avoid production impact.
2. Monitor ABP release notes for future updates addressing this issue.
3. If you require a permanent fix now, consider implementing a custom repository method using a recursive CTE as you described, and replace the default IdentityLinkUserRepository via dependency injection.
4. You may also submit a feature request or upvote existing issues on the ABP GitHub repository to prioritize this fix.

Summary:
The parameter explosion in IdentityLinkUserRepository.GetListAsync() is a known and validated issue. The most effective solution is to implement a recursive CTE or similar efficient query strategy. Until this is available in the official ABP release, your workaround is the best practice.

• The duplicated and cancelled /api/abp/application-configuration requests you observe are typically caused by the browser or frontend framework (Angular) making multiple requests in quick succession, often due to application initialization logic or HTTP interceptors. In ABP Angular applications, this endpoint is called on startup to load configuration and localization data.

• The cancellation and duplication can also occur if a previous request is superseded by a new one before the first completes, or if the user navigates quickly, causing Angular to re-initialize services. The log shows a System.OperationCanceledException, which is expected when a request is aborted.

• This behavior is not unique to ABP; it is common in SPAs (Single Page Applications) and is generally harmless unless it causes user-facing issues or performance problems. If you want to further analyze or reduce such requests, consider:

  • Checking your Angular app's initialization and HTTP interceptor logic for repeated calls.
  • Using browser dev tools to see what triggers the requests.
  • Ensuring that only one configuration request is made on app startup.

• For more details on monitoring HTTP requests in ABP Studio and troubleshooting, see the official documentation:

To address the issue of external font imports in LeptonX's font-bundle.css causing timeouts in restricted environments, you have a few options:

1. Override or Replace font-bundle.css:
   • You can override the default font-bundle.css by providing your own version in your project. Place a custom font-bundle.css in your wwwroot or static assets and ensure it is served instead of the default one. This file can be empty or contain only local font definitions.
   • Example (empty override):

/* font-bundle.css overridden to remove external font imports */

• You can use the same middleware approach you described, or configure static file serving to prioritize your custom file.

2. Remove or Replace the @import in the Build Pipeline:

   • If you control the build process, you can remove or comment out the @import line in font-bundle.css before deployment, or replace it with a local font-face definition.

3. Use Local Fonts:

   • Download the required font files (e.g., Inter) and serve them from your own server. Update font-bundle.css to use local @font-face rules pointing to your internal URLs.

4. No Built-in Configuration (as of v9.2.3):

   • There is currently no built-in or documented configuration option in LeptonX to disable or redirect the remote font import in font-bundle.css. Overriding the file or intercepting the request, as you have done, is the recommended approach for now.

This approach aligns with common ABP and LeptonX theme customization practices for restricted environments.

To ensure OpenIddict uses the latest (unexpired) certificates and avoids downtime when certificates expire, you need to register both the new and old certificates in the credentials collection during key rollover. OpenIddict will only use valid (unexpired) certificates for signing and encryption, and will refuse expired ones. If only expired certificates are present, authentication will fail and your site will go offline.

Solution Steps:

1. Register Multiple Certificates for Key Rollover:
   • When you renew your certificate (e.g., every 3 months with Let's Encrypt), add both the new and the previous certificate in your OpenIddict configuration. This allows OpenIddict to use the valid one and ignore expired ones.
   • Example:

PreConfigure<OpenIddictServerBuilder>(serverBuilder =>
     {
         serverBuilder.AddSigningCertificate(new X509Certificate2("old-cert.pfx", "oldPassword"));
         serverBuilder.AddSigningCertificate(new X509Certificate2("new-cert.pfx", "newPassword"));
     });

• Remove the expired certificate after confirming the new one is in use.

2. Automate Certificate Renewal and Reload:

   • Automate the process of copying the new certificate to your deployment and updating the configuration.
   • Restart the AuthServer application after updating certificates to ensure OpenIddict reloads them.

3. Self-Signed/Expired Certificates:

   • OpenIddict does not allow expired certificates for security reasons.
   • For development, you can use self-signed certificates, but for production, always use valid, non-expired certificates.

4. Troubleshooting:

   • If you see errors like When using X.509 encryption credentials, at least one of the registered certificates must be valid, it means all provided certificates are expired or invalid.
   • Ensure the .pfx file is present, the password is correct, and the certificate is not expired.

• The error occurs because ABP Suite is generating a using importContryProj.ManagementService.Shared; statement, but there is no Shared project or namespace in your microservice solution. In ABP microservice templates, the "Shared" project is not created by default for each service; it is only present in some monolithic or modular setups.

• When you add a navigation property (relation) between entities in a microservice service (like ManagementService), ABP Suite expects a Shared project to exist for DTO sharing, but your solution structure does not include it. This results in the CS0234 error: The type or namespace name 'Shared' does not exist in the namespace.

• To resolve this:

  1. Remove or comment out the using importContryProj.ManagementService.Shared; line in the generated files.
  2. If you need to share DTOs or contracts between services, create a new Shared project (e.g., importContryProj.ManagementService.Shared) and move shared DTOs/interfaces there. Then, reference this project from your other projects as needed.
  3. Alternatively, keep all contracts in the Application.Contracts project and update your usings accordingly.

• This is a known limitation when using ABP Suite with microservice templates, as the code generator assumes a Shared project exists for each service. You may need to adjust the generated code manually or create the missing Shared project.

This approach aligns with common ABP microservice conventions, but specific official documentation for this exact scenario is not available.

To add Azure AD as an external provider with dynamic options in ABP, you need to ensure that the dynamic options are properly initialized before the authentication middleware tries to use them. The error you are seeing (ArgumentNullException: Value cannot be null. (Parameter 'ClientId')) occurs because the ClientId (and possibly other required properties) are not set at application startup, so the OpenIdConnect middleware fails validation.

Here's the correct approach for dynamic external login providers in ABP:

1. Register Dynamic Options and Post-Configure Handler

   You must use .WithDynamicOptions<OpenIdConnectOptions, OpenIdConnectHandler>() after adding the OpenIdConnect provider, and register a post-configure handler to ensure dynamic properties are set before validation.

context.Services.AddAuthentication()
       .AddOpenIdConnect("AzureOpenId", "Azure AD", options =>
       {
           options.ResponseType = OpenIdConnectResponseType.CodeIdToken;
           options.RequireHttpsMetadata = false;
           options.SaveTokens = true;
           options.GetClaimsFromUserInfoEndpoint = true;
           options.Scope.Add("email");
           options.ClaimActions.MapJsonKey(ClaimTypes.NameIdentifier, "sub");
           options.CallbackPath = configuration["AzureAd:CallbackPath"]; // Optional if dynamic
       })
       .WithDynamicOptions<OpenIdConnectOptions, OpenIdConnectHandler>(
           "AzureOpenId",
           options =>
           {
               options.WithProperty(x => x.Authority);
               options.WithProperty(x => x.ClientId);
               options.WithProperty(x => x.ClientSecret, isSecret: true);
           }
       );

   context.Services.TryAddEnumerable(
       ServiceDescriptor.Singleton<
           IPostConfigureAccountExternalProviderOptions<OpenIdConnectOptions>,
           OpenIdConnectPostConfigureAccountExternalProviderOptions>());

2. Implement the Post-Configure Handler

   This ensures that after dynamic properties are set, the options are re-validated:

public class OpenIdConnectPostConfigureAccountExternalProviderOptions : IPostConfigureAccountExternalProviderOptions<OpenIdConnectOptions>
   {
       private readonly IEnumerable<IPostConfigureOptions<OpenIdConnectOptions>> _postConfigureOptions;
       public OpenIdConnectPostConfigureAccountExternalProviderOptions(IEnumerable<IPostConfigureOptions<OpenIdConnectOptions>> postConfigureOptions)
       {
           _postConfigureOptions = postConfigureOptions;
       }
       public Task PostConfigureAsync(string name, OpenIdConnectOptions options)
       {
           foreach (var configureOption in _postConfigureOptions)
           {
               configureOption.PostConfigure(name, options);
           }
           return Task.CompletedTask;
       }
   }

3. Do Not Set Required Properties to Null at Startup

   Do not leave ClientId, Authority, etc., unset at startup. The dynamic provider system will inject them at runtime, but the post-configure handler is required to ensure this happens after all dynamic properties are available.

4. Summary

   • Use .WithDynamicOptions after .AddOpenIdConnect.
   • Register the IPostConfigureAccountExternalProviderOptions implementation.
   • Do not set required properties to null at startup; let the dynamic system handle them.

This approach ensures that the OpenIdConnect middleware does not throw validation errors at startup and that your dynamic configuration is applied correctly.

• In a distributed ABP Auth Server setup (such as Azure Aspire with multiple instances), you must ensure that both Data Protection keys and OpenIddict cryptographic keys are shared and synchronized across all instances. If not, you will see errors like "invalid_grant", "invalid_token", or "The signing key associated to the specified token was not found."

• Using Azure Cache for Redis is a valid approach, but you must ensure:

  1. All instances use the same Redis connection string.
  2. Data Protection is configured to persist keys in Redis (not in-memory or local file).
  3. OpenIddict is configured to use distributed key storage (not ephemeral or per-instance).

• To make your ABP Auth Server reliable in this environment:

  1. Configure Data Protection to use Redis for key storage:

context.Services.AddDataProtection()
         .PersistKeysToStackExchangeRedis(redis, "DataProtection-Keys");

 See: [Distributed Data Protection](https://abp.io/docs/abp/latest/Distributed-Data-Protection)

2. Configure OpenIddict to use distributed key storage (not ephemeral keys):

options.AddDevelopmentEncryptionCertificate()
            .AddDevelopmentSigningCertificate();
     // For production, use a persisted certificate or key storage

 See: [Distributed OpenIddict](https://abp.io/docs/abp/latest/Distributed-OpenIddict)

3. Ensure Redis is healthy and accessible from all instances. Any network or configuration issue can cause key desync.

4. If you want to remove Redis, you must use another distributed key store (e.g., Azure Blob Storage for Data Protection, or a shared certificate for OpenIddict). Do not use in-memory or local file storage in a multi-instance environment.

5. Restart all instances after changing key storage configuration to ensure all use the same keys.

• If you see "The signing key associated to the specified token was not found," it means the instance that issued the token is not sharing its keys with others. This is almost always a misconfiguration of Data Protection or OpenIddict key storage.

• For more details and code samples, see:

  • Distributed Cache
  • Distributed Data Protection
  • Distributed OpenIddict

Summary:
You must use a distributed key store (like Redis or Azure Blob Storage) for both Data Protection and OpenIddict keys, and ensure all instances are configured identically. Do not use local or ephemeral keys in a multi-instance environment.

To address your issue with user-level permissions not being applied in an ABP solution using the OpenIddict module (instead of IdentityServer), here are the key points and steps you should follow:

1. User vs. Role Permissions in ABP

   • ABP's permission system supports granting permissions directly to users or via roles.
   • If a permission is granted to a user, it should be effective immediately (after cache refresh, logout/login, etc.), just like role-based permissions.

2. OpenIddict vs. IdentityServer

   • The workaround from the referenced ticket (disabling claim type updates in IdentityServer) is specific to IdentityServer and not required for OpenIddict.
   • OpenIddict does not override or remap ABP claim types by default, so you do not need to add the PreConfigureServices code for AbpIdentityServerBuilderOptions.

3. Troubleshooting User Permissions Not Applying

   • Ensure that the user is not only assigned the permission in the UI, but that the permission is granted in the AbpPermissionGrants table with the correct ProviderName (U for user, R for role) and ProviderKey (user ID).
   • Make sure your Blazor WASM client is requesting updated claims after login or after permissions change. Sometimes, the access token or user info is cached and not refreshed.
   • If you are using Redis or distributed cache, ensure that the cache is cleared or invalidated after permission changes.
   • The AuthorizeView component in Blazor checks the current user's claims. If the permission is not present, it may be due to the claims not being refreshed or propagated to the client.

4. Force Claims Refresh for User Permissions

   • ABP uses dynamic claims and may require a refresh for the user's claims after a permission change. In Blazor WASM, this is typically handled by re-authenticating or explicitly triggering a claims refresh.
   • If you are using ABP's dynamic claims system, ensure that the app.UseDynamicClaims() middleware is configured only in the AuthServer and Web projects, not in all microservices.
   • If you have enabled dynamic claims, verify that the AbpClaimsPrincipalFactoryOptions.IsDynamicClaimsEnabled is set appropriately (usually true for dynamic claims).

5. Recommended Steps

   • Log out and log in again after granting user permissions.
   • If using distributed cache (e.g., Redis), flush the cache after permission changes.
   • Ensure that your AuthServer and Web projects are correctly configured for dynamic claims (middleware and options).
   • If the problem persists, check the logs for any errors related to claims or permission fetching.

6. Sample: Dynamic Claims Configuration

// In your AuthServer and Web module
   context.Services.Configure<AbpClaimsPrincipalFactoryOptions>(options =>
   {
       options.IsDynamicClaimsEnabled = true;
   });
   // In Startup/Program.cs
   app.UseDynamicClaims();

7. If You Still Have Issues
   • Double-check that the user's claims are being refreshed and that the access token contains the expected permissions.
   • Use ABP's built-in permission checking methods (e.g., IAuthorizationService.IsGrantedAsync) to debug on the server side.

Sources:

• ABP Permission System
• ABP Dynamic Claims
• ABP Identity Server Module Migration
• ABP Support Ticket 6432

This approach aligns with common ABP conventions for OpenIddict and dynamic claims. If you follow these steps and the issue persists, please check for customizations or middleware that might interfere with claims propagation.
