In ABP MVC applications, throwing a UserFriendlyException should display a user-friendly dialog instead of the raw exception page. If you are seeing the raw exception after upgrading to .NET 9 or ABP Commercial Pro, it is likely due to a missing or misconfigured exception filter or middleware.
Ensure you have the AbpExceptionFilter enabled in your MVC pipeline. In your Startup.cs or module configuration, make sure you have:
services.AddAbpMvcExceptionHandling();
Also, check that you are not running in the Development environment, as the Developer Exception Page will override ABP's user-friendly dialog. In production, ABP's exception handling will show the dialog.
If you have custom error handling middleware or filters, ensure they do not interfere with ABP's exception handling.

To manage user access across multiple tenants without requiring re-login in ABP Framework, you can use the Linked Accounts feature. This allows users to link their accounts from different tenants and switch between them seamlessly without logging in again.
Here's how it works:
This feature is built-in and supported in ABP Framework's account module.

The error message:
System.Exception: This assembly is protected by an unregistered version of Eziriz's ".NET Reactor"! This assembly won't further work.
indicates that one of the assemblies in your solution was built or obfuscated using an unregistered (trial) version of Eziriz's ".NET Reactor" tool. This is not related to ABP Framework or ABP Studio itself, but rather to a third-party or custom assembly in your solution.
How to resolve:
Identify the problematic assembly:
Abc.ProjectionService
).Replace or rebuild the assembly:
Clean and restore packages:
dotnet clean
dotnet nuget locals all --clear
dotnet restore
Check your NuGet sources:
Remove any trial/protected DLLs:
This is not an ABP-specific issue, but a general .NET assembly protection/licensing problem.

Based on your description and the error logs, the issue is related to ABP Suite's handling of the solution configuration, specifically a NullReferenceException
when accessing the MigrationsMigrationsDbContext
property. This is likely caused by a missing or corrupted configuration in the ABP Suite's appsettings.json
for your solution, which can happen if the configuration file is out of sync or incomplete on some developer machines.
Your workaround—manually updating the configuration in ABP Suite's appsettings.json
with the correct paths and values—directly addresses this. This ensures that ABP Suite can properly locate all required projects and context files, preventing the null reference error.
Recommended Steps:
appsettings.json
.appsettings.json
and re-add it using the working configuration.For more details on configuring and troubleshooting ABP Suite solution settings, refer to the official documentation:
This approach aligns with ABP Suite's expected configuration management and should resolve the issue for all team members.

This issue is caused by a false positive from BitDefender, which incorrectly flags the ABP Suite executable as malware. This is a known problem with some antivirus solutions and .NET tools.
As a workaround, you can ask your system administrator to whitelist the ABP Suite installation directory or the specific file in BitDefender. Temporarily disabling BitDefender during installation is another option, but whitelisting is the recommended long-term solution.
ABP Suite is safe to use if downloaded from the official source. You can always reinstall it using the following command:
abp suite install
For detailed installation steps, refer to the official documentation.

To resolve the CrashLoopBackOff issue with the abp-wg-easy container when integrating ABP Studio with a remote Kubernetes cluster, follow these steps:
Check PersistentVolumeClaim (PVC) Status:
pod has unbound immediate PersistentVolumeClaims
. This means the required PVC (abp-wg-easy-config
) is not bound to a PersistentVolume.kubectl get pvc -n waqar
Ensure the PVC is in the Bound
state. If not, you need to create a suitable PersistentVolume or check your storage class configuration.Review StorageClass and Volume Provisioning:
Check Container Logs for More Details:
kubectl logs abp-wg-easy-7d44c4b5fc-852bj -n waqar
Look for specific errors related to configuration, permissions, or storage.Verify Resource Limits:
Network and Service Type:
WireGuard Password Consistency:
Clean Up and Retry:
Cluster Compatibility:
By addressing the PVC binding issue and ensuring your cluster supports the required service types and storage, the CrashLoopBackOff should be resolved.

To ensure that the same warning message ("You are not allowed to log in! Your account is inactive or needs to confirm your email/phone number") appears for both local and external (Google) logins when a user is inactive, you need to implement user status validation in the external login flow as well.
In ABP, the local login typically checks user status in the LoginModel
. For external providers, you should override the external login callback to perform the same validation. Here’s how you can do it:
Override the External Login Callback
In your LoginModel
(or equivalent for external login), override the method that handles the external login callback. After retrieving the user from the external provider, check the IsActive
property (or your custom status logic).
public override async Task<IActionResult> OnGetExternalLoginCallbackAsync(string remoteError = null)
{
// ... existing code to get externalLoginInfo and user
var user = await UserManager.FindByLoginAsync(externalLoginInfo.LoginProvider, externalLoginInfo.ProviderKey);
if (user != null && !user.IsActive)
{
Alerts.Danger("You are not allowed to log in! Your account is inactive or needs to confirm your email/phone number");
return Page();
}
// ... continue with the normal flow
}
Angular UI Handling
Make sure your Angular UI displays the error message returned from the backend. The ABP Angular template typically shows backend validation errors as toasts or inline messages.
Consistent Validation
Ensure that both local and external login flows use the same validation logic for user status. This avoids discrepancies in user experience.
Customizing the Error Message
If you want to customize the error message or localization, use the Alerts.Danger
method or equivalent in your overridden method.
This approach ensures that inactive users receive the same warning regardless of the login method.

In an ABP microservice solution, each microservice manages its own database (SQL Server, PostgreSQL, MongoDB, etc.), and its own permissions, settings, and menu/navigation data are stored in its own database, not in the main app's SQL Server database. This is by design for microservice isolation.
For the Angular UI to display menus and modules from a new microservice, you must:
environment.ts
), so it knows about the new endpoints.Permissions and settings for each microservice are stored in that microservice's own database:
If permissions, settings, or menus are not being created:
For menu/navigation integration:
For MongoDB: It is correct that AbpPermissions and AbpSettings are stored as documents in MongoDB for that microservice. They are not synchronized with SQL Server or other databases.
In summary, each microservice is isolated. To integrate new microservices with the Angular UI:

After upgrading from open source to ABP Commercial (Pro), you must ensure that all new module dependencies (such as SaaS) are properly added to your solution, and that your Entity Framework Core migrations are updated to include the new tables (like SaasTenants).
The error Invalid object name 'SaasTenants'
means the SaaS module's tables were not created in your database, likely because the migration files for these tables were not generated/applied.
Solution Steps:
Verify Module References
[DependsOn(
typeof(AbpSaasEntityFrameworkCoreModule),
// ...other dependencies
)]
public class YourProjectNameEntityFrameworkCoreModule : AbpModule
{
}
DbContext
includes the SaaS configuration:
protected override void OnModelCreating(ModelBuilder builder)
{
base.OnModelCreating(builder);
builder.ConfigureSaas();
// ...other configurations
}
Add Missing Migrations
.EntityFrameworkCore
project directory.dotnet ef migrations add AddedSaasTables
Apply the Migration
dotnet ef database update
DbMigrator
project again to apply the migrations.Check for Other Module Migrations
Upgrade NuGet Packages
Review the Official Migration Guide
If builder.ConfigureOpenIddictPro()
is missing:
builder.ConfigureOpenIddict()
if you do not have the Pro OpenIddict module. If you have the Pro module, ensure the correct NuGet package is referenced.Summary:
SaasTenants
table is due to missing migrations. Add the SaaS module, generate new migrations, and update your database.Sources:

To implement a modern, Fluent-style collapsible sidebar navigation in ABP Framework with LeptonX and Blazor Server, you should leverage the extensibility points provided by LeptonX and ABP’s menu system. Here’s the recommended approach:
Use LeptonX’s Layout Customization LeptonX for Blazor supports layout customization, including sidebar (side menu) and top menu layouts. The sidebar is fully compatible with ABP’s MainMenu and permission-based rendering.
Sidebar Collapsing and Icon/Label Display LeptonX’s sidebar layout natively supports collapsing. When collapsed, only icons are shown; when expanded, both icons and labels are visible. The toggle button is included in the default layout.
Floating and Inline Submenus
Integration with ABP Menu System All menu rendering in LeptonX is based on ABP’s MainMenu and MenuItemViewModel, so your customizations will remain compatible with permission-based menu logic.
Extension Points and Component Replacement LeptonX is designed for extensibility. You can replace the sidebar component using ABP’s component replacement system. This allows you to implement advanced behaviors (like floating submenus and search) while retaining ABP’s menu integration.
Example: Replace the Sidebar Component
Example (pseudo-code):
Configure<AbpReplaceableComponentsOptions>(options =>
{
options.Components["LeptonX.Sidebar"] = typeof(MyCustomSidebar);
});
References:
Summary
This approach ensures your sidebar remains fully integrated with ABP’s menu and permission system, while allowing you to deliver a modern, SaaS-style navigation experience.
