  • The alert you received from Windows Defender (Trojan:Win32/Yomal!rfn) when running ABP Studio or ABP Suite is most likely a false positive. ABP Studio and ABP Suite are official tools distributed by the ABP team, and there are no known reports of malicious code or hijacked dependencies in the official releases.

  • False positives can occur when antivirus software incorrectly flags legitimate software, especially developer tools that perform code generation or automation. This is a common issue with .NET tools and other CLI utilities.

  • To ensure safety:

    1. Download ABP Studio and ABP Suite only from the official website: https://abp.io/studio
    2. Verify the installer hash if available on the download page.
    3. Make sure your antivirus definitions are up to date, and consider submitting the quarantined file to Microsoft for further analysis if you want confirmation.
  • If you are in a corporate environment, you may need to whitelist the ABP Suite executable or folder in your antivirus settings after verifying its source.

To achieve dynamic, efficient extension of your Customers module with extra information from other modules (like Appointments and Finances) in ABP, while maintaining modular boundaries and performance, you should consider the following best practices:

  1. Modular Data Isolation & Integration:

    • Each module (Customers, Appointments, Finances) should own its own data and DbContext.
    • Direct joins across DbContexts are not supported by EF Core and are discouraged in modular architectures for decoupling reasons.
    • Instead, use integration services or events to communicate between modules.
  2. Extending the Customer List with Extra Info:

    • The recommended approach is to use a ViewModel composition pattern at the application or UI layer, not at the entity or DbContext level.
    • Each module can provide a service that contributes extra data for a given set of customer IDs.
    • The Customers module exposes an extension point (e.g., an interface like ICustomerExtraInfoProvider).
    • Appointments and Finances modules implement this interface and register their providers conditionally.
  3. Efficient Data Fetching:

    • When building the customer list, first fetch the customers in a single query.
    • Then, for each registered ICustomerExtraInfoProvider, call a batch method (e.g., GetExtraInfoForCustomersAsync(IEnumerable<Guid> customerIds)) to fetch all needed extra info in one query per module.
    • Compose the final DTO (e.g., CustomerWithExtraInfoDto) by merging the base customer data with the extra info from each provider.
  4. DTO Design:

    • Use a dictionary or a well-defined extension object in your DTO to hold extra info, e.g.:
public class CustomerWithExtraInfoDto : CustomerDto
     {
         public Dictionary<string, object> ExtraInfo { get; set; }
     }
  • Each provider can add its data under a unique key (e.g., "NextAppointmentDate", "LastPaymentDate").
  1. Conditional UI Display:

    • The UI can check for the presence of specific keys in ExtraInfo to decide what to display.
    • This keeps the Customers module agnostic of the specifics of other modules.
  2. Filtering and Advanced Logic:

    • If extra info providers need to filter the customer list, you can allow them to return a filtered set of customer IDs, and intersect these with the base list.
    • For more complex scenarios, consider a two-phase approach: providers can first filter, then contribute extra info.
  3. ABP Guidance:

This approach keeps your modules decoupled, supports dynamic discovery of extra info providers, and ensures efficient data access.

To use EF Core's UseLazyLoadingProxies in an ABP application, all navigation properties (including collections) in your entities must be marked as virtual. However, some ABP modules (such as GDPR) may define their entities without marking navigation properties as virtual. This causes the error you encountered:

System.InvalidOperationException: Property 'GdprRequest.Infos' is not virtual. 'UseChangeTrackingProxies' requires all entity types to be public, unsealed, have virtual properties, and have a public or protected constructor. 'UseLazyLoadingProxies' requires only the navigation properties be virtual.

Key Points

  • EF Core's lazy loading proxies require all navigation properties (including collections) to be virtual.
  • If a module's entity (like GdprRequest.Infos in the GDPR module) does not declare its navigation property as virtual, you cannot use UseLazyLoadingProxies unless you modify the source code of that module.
  • You cannot override or extend the navigation property to make it virtual from outside the module, due to C#'s type system and the way EF Core proxies work.

Workarounds

  1. Do Not Use Lazy Loading Proxies:
    If you depend on ABP modules that do not mark navigation properties as virtual, you cannot use EF Core's lazy loading proxies unless those modules are updated. Instead, use explicit or eager loading (Include, ThenInclude, or ABP's WithDetails).

  2. Request Module Update:
    You can request the maintainers of the ABP modules (such as GDPR) to update their entities to make navigation properties virtual. This is the only way to enable lazy loading proxies for those entities.

  3. Fork and Patch (Not Recommended for Commercial Modules):
    If you have access to the module's source code, you could fork and update the navigation properties to be virtual. However, this is not recommended for commercial modules or if you want to keep receiving updates.

Example: Eager Loading Instead

Instead of relying on lazy loading, use eager loading:

var gdprRequest = await _gdprRequestRepository
    .WithDetails(x => x.Infos)
    .FirstOrDefaultAsync(x => x.Id == id);

Or with EF Core's Include:

var gdprRequest = await dbContext.GdprRequests
    .Include(x => x.Infos)
    .FirstOrDefaultAsync(x => x.Id == id);

Summary

You cannot use UseLazyLoadingProxies with ABP modules that do not declare navigation properties as virtual. Use eager or explicit loading as an alternative, or request the module authors to update their code.

When you encounter a large number of AbpDbConcurrencyException errors during simultaneous user login or registration, it typically indicates that multiple processes are trying to update the same database record at the same time. In ABP Framework, this is managed using Optimistic Concurrency Control, which relies on a concurrency token (like ConcurrencyStamp) to detect conflicting updates.

Why This Happens

  • The OpenIddict token endpoint (/connect/token) updates token or user records as part of the authentication flow.
  • If many users log in or register at the same time, concurrent updates to the same user or token records can cause concurrency conflicts.
  • ABP and EF Core throw AbpDbConcurrencyException (wrapping DbUpdateConcurrencyException) when the concurrency token in the database does not match the one in the entity being updated.

How to Mitigate

  1. Understand the Concurrency Model
    ABP uses Optimistic Concurrency Control. When an update occurs, the ConcurrencyStamp is checked. If it has changed since the entity was loaded, a concurrency exception is thrown.
    See:

  2. Reduce Simultaneous Updates

    • Avoid updating the same user or token record in multiple parallel requests.
    • For login/registration, ensure that your client does not retry or send multiple requests for the same user at the same time.
  3. Handle Concurrency Exceptions Gracefully

    • Catch AbpDbConcurrencyException in your application layer and provide a user-friendly message or retry logic if appropriate.
    • For background or batch operations, consider implementing a retry policy with a backoff.
  4. Database and Index Tuning

    • Ensure your database is not under heavy lock contention.
    • Make sure indexes are properly set up for the tables involved in authentication and token management.
  5. Review Customizations

    • If you have custom logic in user or token update flows, ensure you are not causing unnecessary updates or holding entities longer than needed.
  6. Upgrade Considerations

    • While you mentioned not planning to upgrade to v9 yet, note that newer versions may include improvements or bug fixes related to concurrency handling.

Example: Handling Concurrency in ABP

try
{
    // Your update logic here
}
catch (AbpDbConcurrencyException ex)
{
    // Handle the concurrency conflict, e.g., reload entity and retry or inform the user
}

Additional Notes

  • This is not related to notification services or HandleNonSuccessAndDebuggerNotification directly; it's a result of how EF Core and ABP handle concurrent updates.
  • If you have a high-traffic authentication system, consider scaling out your authentication server and reviewing your token/user update logic.

To implement an ICurrentCompany service similar to ICurrentTenant in a layered Blazor WASM solution, you can follow these steps:

  1. Define the ICurrentCompany Interface:
public interface ICurrentCompany
   {
       Guid? CompanyId { get; }
       string CompanyCode { get; }
       Task ChangeAsync(Guid companyId, string companyCode);
   }
  1. Implement the Service:

    • Store the selected company in a cookie (or local storage) on the client.
    • On the server, read the cookie and set the current company context for each request.

    Example implementation for Blazor WASM (client-side):

public class CurrentCompany : ICurrentCompany
   {
       private readonly IJSRuntime _jsRuntime;
       private const string CompanyCookieName = "CurrentCompany";

       public Guid? CompanyId { get; private set; }
       public string CompanyCode { get; private set; }

       public CurrentCompany(IJSRuntime jsRuntime)
       {
           _jsRuntime = jsRuntime;
       }

       public async Task ChangeAsync(Guid companyId, string companyCode)
       {
           CompanyId = companyId;
           CompanyCode = companyCode;
           await _jsRuntime.InvokeVoidAsync("BlazorCookies.Set", CompanyCookieName, companyId.ToString());
           // Optionally store companyCode as well
       }

       public async Task InitializeAsync()
       {
           var companyIdString = await _jsRuntime.InvokeAsync<string>("BlazorCookies.Get", CompanyCookieName);
           if (Guid.TryParse(companyIdString, out var companyId))
           {
               CompanyId = companyId;
           }
       }
   }
  • Use a JS interop library (like BlazorCookies) to manage cookies in Blazor WASM.
  1. Register the Service:
builder.Services.AddScoped<ICurrentCompany, CurrentCompany>();
  1. Set the Company from the UI:

    • When a user selects a company from the dropdown, call ChangeAsync on your ICurrentCompany service.
  2. Server-Side:

    • On the backend, create a middleware or a custom provider to read the company cookie from the request and set the company context for the current user/session.
    • You can use a custom data filter similar to ABP's multi-tenancy filter to restrict data by company.
  3. Data Filtering:

    • Implement a custom data filter for company-based filtering, similar to how ABP handles multi-tenancy:
public interface ICompanyFilter
     {
         Guid? CompanyId { get; }
     }
 - Apply this filter to your entities and queries.

References for Custom Filters and Claims:

This approach aligns with ABP conventions for context services and data filtering, allowing you to change the current company at runtime and persist the selection in a cookie, similar to how tenants are managed.

  • The error The entity type 'ExtraPropertyDictionary' requires a primary key to be defined typically occurs when a type that is not meant to be an EF Core entity is being picked up by your DbContext's model builder. ExtraPropertyDictionary is an internal type used by ABP for extra properties and should not be mapped as an entity.

  • This usually happens if you accidentally add a DbSet<ExtraPropertyDictionary> to your DbContext, or if you use modelBuilder.Entity<ExtraPropertyDictionary>() in your OnModelCreating method. EF Core tries to map it as a table, but it has no primary key, causing the error.

Solution Steps:

  1. Check Your DbContext:

    • Ensure you do NOT have any DbSet<ExtraPropertyDictionary> in your DbContext.
    • Do NOT call modelBuilder.Entity<ExtraPropertyDictionary>() in OnModelCreating.
  2. Review Entity Extension Mappings:

    • If you are using ABP's module/entity extension system, make sure you are only mapping your own entities or valid ABP module entities.
    • Do not attempt to map or extend ExtraPropertyDictionary.
  3. Clean and Rebuild:

    • Clean your solution and rebuild to ensure no old artifacts are causing the issue.
  4. Check for Accidental Usages:

    • Search your solution for any accidental references to ExtraPropertyDictionary in your entity or DbContext code.
  5. If You Need to Add Extra Properties:

    • Use ABP's recommended way to extend entities, as described in the documentation below.

Example for extending an entity (do NOT use ExtraPropertyDictionary directly):

ObjectExtensionManager.Instance.Modules()
    .ConfigureIdentity(identity =>
    {
        identity.ConfigureUser(user =>
        {
            user.AddOrUpdateProperty<string>("CustomProperty");
        });
    });

To refresh the access token using a refresh token in a Blazor Server application with ABP, follow these steps:

  1. Request the offline_access scope:
    • In your authentication configuration (typically in Startup.cs or the module class), add the offline_access scope to the OpenIdConnect options:
options.Scope.Add("offline_access");
  • This ensures the refresh_token is issued by the server.
  1. Ensure cookie and refresh token lifetimes are aligned:
    • The default ABP Blazor Server template uses cookie authentication. Set the cookie expiration to match the refresh token lifetime:
.AddCookie("Cookies", options =>
     {
         options.ExpireTimeSpan = TimeSpan.FromDays(365); // Example: 1 year
     })
  • It is recommended to keep Cookie ExpireTimeSpan and the Refresh Token lifetime the same.
  1. Handle token expiration and refresh:

    • ABP does not automatically refresh the access token in Blazor Server. You need to implement logic to detect token expiration and use the refresh token to obtain a new access token.
    • You can use the OidcClient or similar libraries to perform the refresh token flow, or call the token endpoint manually with the refresh_token grant type.
  2. Sign out users after token expiration (optional but recommended):

    • ABP provides extension methods to sign out users after the access token expires. This ensures the UI reflects the authentication state correctly.
    • See the following PR for reference and code you can adapt:
      https://github.com/abpframework/abp/pull/15876
  3. Example: Adding offline_access and configuring OpenIdConnect in Blazor Server

services.AddAuthentication(options =>
   {
       options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
       options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
   })
   .AddCookie("Cookies", options =>
   {
       options.ExpireTimeSpan = TimeSpan.FromDays(365);
   })
   .AddOpenIdConnect(options =>
   {
       // ... other options ...
       options.Scope.Add("offline_access");
   });
  1. Refreshing the token:
    • When the access token expires, use the refresh token to request a new access token from the token endpoint:
var response = await httpClient.RequestRefreshTokenAsync(new RefreshTokenRequest
     {
         Address = disco.TokenEndpoint,
         ClientId = "your-client-id",
         ClientSecret = "your-client-secret",
         RefreshToken = "your-refresh-token"
     });
  • Store the new access and refresh tokens securely.

For a complete example and more details, see the official ABP documentation and community articles below.

This error (Value cannot be null. (Parameter 'path')) during the "ApplicationObjectMappingCommand" step in ABP Suite CRUD generation is a known issue, especially in microservice or modular solutions. It typically occurs when ABP Suite cannot find or resolve the expected file path for the Application layer's AutoMapper profile or related mapping files.

How to Resolve

  1. Check Application Layer Structure

    • Ensure your Application project contains an AutoMapper profile (e.g., YourModuleApplicationAutoMapperProfile.cs) in the correct folder (usually under Application or Application.Contracts).
    • The file should be included in the .csproj and not excluded or missing.
  2. Verify File Paths in Suite Configuration

    • ABP Suite expects certain files to exist at standard locations. If you have moved, renamed, or deleted mapping/profile files, restore them or update their paths.
    • If you have custom folder structures, try reverting to the default ABP module layout.
  3. Check for Multiple or Missing *DbContextModelCreatingExtensions.cs Files

    • Having more than one *DbContextModelCreatingExtensions.cs file in your module can confuse Suite. Keep only one such file per module and move all configuration methods into it.
  4. Regenerate or Restore Missing Files

    • If you have deleted or renamed any of the following, restore them:
      • *ApplicationAutoMapperProfile.cs
      • *DbContextModelCreatingExtensions.cs
    • If you are missing an AutoMapper profile, create one:

public class TenantDomainApplicationAutoMapperProfile : Profile { public TenantDomainApplicationAutoMapperProfile() { // Mapping configuration here } }


5. **Remove and Re-Add Solution in Suite**
   - Remove your solution from ABP Suite and add it again to refresh its internal file path cache.

6. **Check for Known Issues**
   - This is a documented problem in the ABP support portal. See the following for more details and workarounds:
     - [ABP Suite CRUD Generator: startIndex must be non-negative](https://abp.io/support/questions/9489)

### Additional Notes

- If you are using a microservice module, ABP Suite may not fully support CRUD code generation for all module types.
- If you have a custom or non-standard folder structure, try aligning it with the default ABP template.

  • When using ABP's Angular service proxy generation for a DDD/module-based solution, the proxy generator only creates proxies for HTTP APIs that are exposed and discoverable by the backend's API definition endpoint. If your AppService from the "cards" module is not being generated, check the following:
  1. Ensure the AppService is Publicly Exposed

    • The AppService must be registered and exposed via the auto API controller system.
    • It should be decorated with the appropriate attributes (e.g., [RemoteService] or [ApiController] if needed) and reside in a namespace that is included in the API definition.
  2. Module Must Be Properly Integrated

    • The module (e.g., Gaming.Module.Cards) must be added as a dependency in your Host application and properly configured in the module system.
  3. Backend Host Must Be Running

    • The backend (HttpApi.Host) must be running and accessible when you run abp generate-proxy.
    • If using Visual Studio, do not use IIS Express; run the Host project directly.
  4. Correct Module Name in Command

    • The -m cards parameter should match the remote service/module name as registered in your backend.
    • You can check the available remote service names by visiting /api/abp/api-definition on your running backend.
  5. Check API Definition Endpoint

    • Visit https://<your-host>/api/abp/api-definition?includeTypes=true to verify if your AppService endpoints are listed. If not, the proxy generator will not generate them.
  6. Re-run Proxy Generation

    • After confirming the above, run:
      abp generate-proxy -t ng -m cards
      
    • If you have multiple modules, ensure you specify the correct one.
  7. Check for Errors or Warnings

    • Review the CLI output for any errors or warnings about missing modules or services.

If your AppService is still not being generated, ensure that:

  • The service is not internal/private.
  • The module is referenced and loaded in the Host's module dependency tree.
  • The service is not excluded by any configuration.

This tooltip issue ("You do not have permission to perform any action") after upgrading to ABP 9.2.0 is a known behavioral change related to permission checks in the Blazor UI's DataGrid and EntityAction components. In recent ABP versions, the framework shows this tooltip when no visible actions are available to the user due to permission restrictions.

However, in some cases, this tooltip may appear prematurely—before permissions are fully resolved—especially after a page refresh or initial load. This is a side effect of how permission checks and UI rendering are handled in the new version.

Workaround / Recommendations

  • This tooltip is triggered when all actions in the EntityAction group are hidden (typically due to permission checks).
  • If your users have the correct permissions but still see this tooltip, it may be due to asynchronous permission resolution or caching delays.
  • As a workaround, you can explicitly control the visibility of actions using the Visible property and ensure permission checks are completed before rendering the DataGrid or EntityAction components.

Example:

new EntityAction<MyEntity>(
    "Edit",
    L["Edit"],
    visible: context => PermissionChecker.IsGrantedAsync("MyPermissionName").Result // or use async pattern properly
)
  • If you are using custom actions, ensure that the Visible property is set based on the user's permissions and that permission checks are not delayed.

  • If the issue persists on built-in pages, it is likely a framework-level behavior. You can monitor the official migration guide and GitHub issues for updates or patches:

Currently, there is no official configuration to suppress this tooltip globally, but you can override the tooltip text or logic in your custom components if needed.

If this behavior is blocking your users, consider reporting it on the ABP GitHub repository or support channels, as it may be addressed in a future patch.
