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);
});

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.

In ABP microservice architecture, when Microservice B (event handler) needs to call a protected API on Microservice C, you must ensure that B can authenticate itself to C. Since the event is not triggered by a user HTTP request, you cannot forward a user access token. The recommended approach is to use client credentials flow for service-to-service communication.
Steps:
Example (token acquisition in B):
var client = new HttpClient();
var disco = await client.GetDiscoveryDocumentAsync("https://identity-server-url");
var tokenResponse = await client.RequestClientCredentialsTokenAsync(new ClientCredentialsTokenRequest
{
Address = disco.TokenEndpoint,
ClientId = "microservice-b-client-id",
ClientSecret = "microservice-b-secret",
Scope = "microservice-c-scope"
});
var accessToken = tokenResponse.AccessToken;
Use this accessToken in the Authorization header when calling C:
client.SetBearerToken(accessToken);
var response = await client.GetAsync("https://microservice-c/api/protected-endpoint");
ABP provides infrastructure to automate this with dynamic HTTP clients and remoting modules. See the "Zero Trust Microservice Architecture" article for a full implementation, including token caching and automatic renewal.

ABP Framework currently does not natively support global EnableRetryOnFailure for all database operations, especially for OpenIddict and some internal modules. This is a known limitation, as documented in the following discussions:
The root cause is that OpenIddict (and some other ABP modules) use their own DbContext or transaction management, which may not be compatible with EF Core's built-in connection resiliency when EnableRetryOnFailure is enabled globally. This can lead to unexpected behavior or errors.
As of ABP v9.1.3, there is no official workaround that enables seamless, global retry logic for all database operations—including those performed by OpenIddict—without risking side effects or instability.
The only reliable approaches currently are:
For general EF Core connection resiliency recommendations, see the official Microsoft documentation:
If global retry support is a strict requirement for your production environment, you may need to consider alternative authentication modules or frameworks until ABP provides full compatibility.

The ABP Framework does not provide built-in antivirus or malware scanning for uploaded files. When implementing file upload/download using Angular and ABP, the framework handles file transfer and storage, but antivirus detection must be integrated separately at the backend.
To detect malicious files during upload, you should integrate a server-side antivirus scanning solution (such as ClamAV or a commercial antivirus API) in your application service or controller that processes the uploaded file. The Angular frontend cannot detect or interact with antivirus systems directly; this must be handled on the server after receiving the file.
The typical ABP file upload process involves sending the file from Angular to an app service (using IRemoteStreamContent or FormData). After receiving the file stream, you can scan the file before saving or processing it further.
Example (server-side, C#):
public async Task<Guid> UploadFileAsync(IRemoteStreamContent file)
{
using var stream = file.GetStream();
// Call your antivirus scanning logic here, e.g., ClamAV or other service
bool isClean = await MyAntivirusScanner.ScanAsync(stream);
if (!isClean)
{
throw new UserFriendlyException("Malicious file detected.");
}
// Save file if clean
// ...
}
Review your backend file handling logic to ensure antivirus scanning is performed before saving or serving files. If antivirus scanning is missing or misconfigured, malicious files may not be detected.

To resolve the error regarding the missing 'Volo.Abp.Account.Pro.Public.Web' assembly when migrating from IdentityServer to OpenIddict in your auth-server, you need to ensure that all IdentityServer-related package references are fully replaced with their OpenIddict counterparts, as described in the official ABP migration guide.
Here are the key steps you should follow:
Update Package References:
<PackageReference Include="Volo.Abp.Account.Pro.Public.Web.IdentityServer" ... />
<PackageReference Include="Volo.Abp.AspNetCore.Authentication.JwtBearer" ... />
<PackageReference Include="Volo.Abp.Account.Pro.Public.Web.OpenIddict" Version="8.1.2" />
Update Module Dependencies:
using Volo.Abp.IdentityServer;
typeof(AbpAccountPublicWebIdentityServerModule)
using Volo.Abp.OpenIddict;
typeof(AbpAccountPublicWebOpenIddictModule)
Clean and Rebuild:
bin and obj folders in your solution.dotnet clean and dotnet build to ensure all old references are removed.Restore NuGet Packages:
dotnet restore to ensure all required packages are downloaded.nuget.config is correct and you are authenticated.Check for Transitive Dependencies:
Version Consistency:
If you follow these steps and the error persists, double-check that there are no lingering references to Volo.Abp.Account.Pro.Public.Web.IdentityServer or Volo.Abp.Account.Pro.Public.Web in any project or module dependency.
For more details, see the official migration guide:
This approach is based on the official ABP documentation and aligns with the recommended migration process.

To restore sidebar/menu click functionality after customizing the LeptonX layout in your ABP Blazor Web App, you must ensure that your custom layout component inherits from the correct base layout and is registered to replace the default one. This is required because the built-in LeptonX layouts contain the logic and event handling for menu toggling and other interactive features.
Solution:
Inherit from the Correct Base Layout:
Your custom layout Razor file must inherit from SideMenuLayout (or the appropriate LeptonX layout base class), not just LayoutComponentBase. This ensures all built-in logic and event handlers are included.
Example:
@using Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.Components.ApplicationLayout
@using Volo.Abp.DependencyInjection
@inherits SideMenuLayout
@attribute [ExposeServices(typeof(SideMenuLayout))]
@attribute [Dependency(ReplaceServices = true)]
<!-- Your custom markup here -->
Register the Custom Layout:
Use the [ExposeServices] and [Dependency(ReplaceServices = true)] attributes to ensure your layout replaces the default one.
Do Not Remove Required Markup or Logic: When customizing, avoid removing essential elements or logic (such as menu toggles, event handlers, or component references) from the base layout. If you need to add or move elements, do so within the structure provided by the base class.
Example Custom Layout:
@using Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.Components.ApplicationLayout
@using Volo.Abp.DependencyInjection
@inherits SideMenuLayout
@attribute [ExposeServices(typeof(SideMenuLayout))]
@attribute [Dependency(ReplaceServices = true)]
<div>
<div id="lpx-wrapper">
<MainHeader />
<div class="lpx-content-container">
<div class="lpx-content-wrapper">
<div class="lpx-content">
<ContentToolbar />
<PageAlert />
<UiPageProgress />
@Body
<DynamicLayoutComponent />
<UiMessageAlert />
<UiNotificationAlert />
</div>
</div>
<footer>
<Footer />
</footer>
</div>
<MobileNavbar />
<div class="lpx-toolbar-container">
<MainHeaderToolbar />
</div>
</div>
</div>
Check for JavaScript or CSS Issues: If you have removed or altered required scripts/styles, restore them to ensure interactive features work.
Summary:
Always inherit from the correct LeptonX layout base class and use the required attributes to replace the default layout. This preserves all built-in interactive features, including sidebar toggling.

To explicitly invalidate or revoke access tokens on logout in an ABP.IO application using OpenIddict, you need to implement token revocation logic, as JWT access tokens are typically stateless and remain valid until expiration unless actively revoked.
Here’s how you can achieve this:
Enable Token Revocation in OpenIddict:
Call the Revocation Endpoint on Logout:
/connect/revocation endpoint with the token to be revoked. This can be done from your client or server-side code.Example HTTP request:
POST /connect/revocation
Content-Type: application/x-www-form-urlencoded
token={access_token}&token_type_hint=access_token&client_id={client_id}&client_secret={client_secret}
Custom Logic with OpenIddict Events (Optional):
OpenIddictServerEvents.ProcessSignOutContext.public class SignOutEventHandler : IOpenIddictServerHandler<OpenIddictServerEvents.ProcessSignOutContext>
{
public static OpenIddictServerHandlerDescriptor Descriptor { get; }
= OpenIddictServerHandlerDescriptor.CreateBuilder<OpenIddictServerEvents.ProcessSignOutContext>()
.UseSingletonHandler<SignOutEventHandler>()
.SetOrder(100_000)
.SetType(OpenIddictServerHandlerType.Custom)
.Build();
public ValueTask HandleAsync(OpenIddictServerEvents.ProcessSignOutContext context)
{
// Custom logic here (e.g., revoke tokens)
return ValueTask.CompletedTask;
}
}
Register the handler in your module:
public override void PreConfigureServices(ServiceConfigurationContext context)
{
PreConfigure<OpenIddictServerBuilder>(serverBuilder =>
{
serverBuilder.AddEventHandler(SignOutEventHandler.Descriptor);
});
}
