To implement a dynamic tab navigation system in a Blazor Web App using the LeptonX theme, while ensuring full theme integration and localized tab titles, follow these recommendations:
Integrate Tabs at the Layout Level
SideMenuLayout.razor), not inside the @Body.Example (simplified):
@inherits SideMenuLayout
<TelerikRootComponent>
<div id="lpx-wrapper">
<MainHeader />
<div class="lpx-content-container">
<div class="lpx-topbar-container">
<div class="lpx-topbar">
<Breadcrumbs />
</div>
</div>
<div class="lpx-content-wrapper">
<div class="lpx-content">
<RouterTabs>
<!-- Tab content will be rendered here -->
</RouterTabs>
<ContentToolbar />
<PageAlert />
<LayoutHook Name="@LayoutHooks.Body.First" Layout="@StandardLayouts.Application" />
@Body
<LayoutHook Name="@LayoutHooks.Body.Last" Layout="@StandardLayouts.Application" />
<DynamicLayoutComponent />
<UiMessageAlert />
<UiNotificationAlert />
<UiPageProgress />
</div>
</div>
<footer>
<Footer />
</footer>
</div>
<MobileNavbar />
<div class="lpx-toolbar-container">
<MainHeaderToolbar />
</div>
</div>
</TelerikRootComponent>
RouterTabs so it wraps or coordinates with the @Body and other layout elements.Ensure Routed Components Use the Layout
SideMenuLayout).Localize Tab Titles
@inject IStringLocalizer<YourResource> L
<RouterTabs>
@foreach (var tab in Tabs)
{
<Tab Title="@L[tab.LocalizationKey]">
<!-- Tab content -->
</Tab>
}
</RouterTabs>
"Menu:TenantManagement").Dynamic Tab Management
Alternative: Custom Tab System
<RouteView> or <DynamicComponent>, ensuring each uses the correct layout.Reference Implementation
By following this approach, you ensure that each tab renders with the full LeptonX/ABP layout and displays localized titles, providing a consistent and integrated user experience.

To ensure your ABP Framework MVC Core multi-layer website defaults to Arabic (or any language) when opened in a new incognito window, you need to configure the default culture and ensure the localization middleware is set up correctly. By default, ABP uses the browser's language or falls back to English if no preference is found.
Solution Steps:
Set the Default Culture in Startup:
In your Startup.cs (or the module's ConfigureServices), configure the RequestLocalizationOptions to set Arabic as the default culture:
services.Configure
2. **Ensure Middleware Order:**
In your `OnApplicationInitialization` or `Configure` method, make sure `UseRequestLocalization()` is called before `UseRouting()`:
```csharp
app.UseRequestLocalization();
app.UseRouting();
// ... other middleware
Check for URL-Based Localization (Optional but Recommended):
For SEO and user experience, consider using URL-based localization (e.g., /ar/home). This ensures the language is explicit in the URL and not just based on cookies or browser settings. You can implement this using custom routing and middleware as described in the ABP community article:
RouteDataRequestCultureProvider to extract the culture from the URL.See the full working sample and implementation details here:
Clear Browser Cache/Cookies: Incognito windows do not retain cookies or local storage, so the default language will be used unless the language is specified in the URL or detected from the browser.
Verify Language Switcher: If you have a language switcher, ensure it sets the culture in the URL or via a cookie, and that your localization middleware respects this.
By following these steps, your website will default to Arabic for new users and in incognito windows, unless another language is explicitly selected.

To restore the previous "My Account" experience in your Angular UI after upgrading to ABP 9.2, you should ensure that the Angular Account Module is properly integrated and that the user menu is configured to use the Angular route for the account/profile page, not the MVC endpoint.
Starting from ABP v4.3, the "My Account" link in the user dropdown should route to the Angular account module page instead of opening the MVC profile page in a new tab. If it opens in a new tab or loses the left navigation, it usually means the menu item is still pointing to the MVC endpoint or is using a target that opens a new window.
How to fix:
Check Your Menu Contributor:
*.MenuContributor.ts (or similar), ensure the "My Account" menu item uses the Angular route, e.g., /account/manage, and does not set target: '_blank' or a full external URL.Example:
context.menu.addItem( new ApplicationMenuItem( 'Account.Manage', 'My Account', '/account/manage', // Angular route 'fa fa-cog', 1000 ) );
2. **Remove/Update Old Links:**
- If you have a link like `https://your-auth-server/Account/Manage?...` or set `target: '_blank'`, update it to use the Angular route and default target.
3. **Verify Account Module is Added:**
- Make sure `@volo/abp.ng.account` is included in your Angular project and imported in your `app.module.ts`.
```typescript
import { AccountConfigModule } from '@volo/abp.ng.account/config';
// ...
imports: [
// ...
AccountConfigModule.forRoot(),
]

sqlOptions.CommandTimeout(7200) in the Configure method is the correct approach for configuring EF Core command timeout in ABP Framework.DbContextOptions configuration as your runtime code.dotnet ef database update) and some ABP migration utilities may use a different context factory (e.g., UnifiedDbContextFactory or a design-time factory) that does not apply your runtime configuration, including the command timeout.Solution:
UnifiedDbContextFactory (or any IDesignTimeDbContextFactory) also sets the CommandTimeout value:public class UnifiedDbContextFactory : IDesignTimeDbContextFactory<UnifiedDbContext>
{
public UnifiedDbContext CreateDbContext(string[] args)
{
var builder = new DbContextOptionsBuilder<UnifiedDbContext>();
builder.UseSqlServer(
"YourConnectionString",
sqlOptions => sqlOptions.CommandTimeout(7200)
);
return new UnifiedDbContext(builder.Options);
}
}
This ensures that both runtime and migration/CLI tools use the same timeout.
If you are using ABP's migration system, make sure any custom context factory or migration handler also applies the timeout.
After making this change, re-run your migration command.
This approach aligns with common ABP and EF Core conventions for command timeout configuration in both runtime and migration scenarios, but specific official documentation for this exact scenario is not available.

To override the login process in ABP (v9.1, .NET 9), you need to customize the SignInManager and/or the login page logic. This allows you to perform additional operations (such as calling an external API, registering the user if needed, etc.) before completing the login.
Here’s how you can achieve this:
Create a Custom SignInManager
Inherit from the default SignInManager and override the methods you need (e.g., PasswordSignInAsync). This is where you can add your custom logic, such as calling an external API and registering the user if they exist externally but not in your ABP database.
public class CustomSignInManager : Microsoft.AspNetCore.Identity.SignInManager<Volo.Abp.Identity.IdentityUser>
{
public CustomSignInManager(
UserManager<Volo.Abp.Identity.IdentityUser> userManager,
IHttpContextAccessor contextAccessor,
IUserClaimsPrincipalFactory<Volo.Abp.Identity.IdentityUser> claimsFactory,
IOptions<IdentityOptions> optionsAccessor,
ILogger<SignInManager<Volo.Abp.Identity.IdentityUser>> logger,
IAuthenticationSchemeProvider schemes,
IUserConfirmation<Volo.Abp.Identity.IdentityUser> confirmation)
: base(userManager, contextAccessor, claimsFactory, optionsAccessor, logger, schemes, confirmation)
{
}
public override async Task<SignInResult> PasswordSignInAsync(string userName, string password, bool isPersistent, bool lockoutOnFailure)
{
// Call your external API here
var existsExternally = await CheckUserInExternalApi(userName);
if (existsExternally)
{
var user = await UserManager.FindByNameAsync(userName);
if (user == null)
{
// Register the user in ABP
user = new Volo.Abp.Identity.IdentityUser(Guid.NewGuid(), userName, userName + "@yourdomain.com", Guid.Empty);
await UserManager.CreateAsync(user, password);
// Assign roles, etc.
}
}
// Continue with the normal login process
return await base.PasswordSignInAsync(userName, password, isPersistent, lockoutOnFailure);
}
private async Task<bool> CheckUserInExternalApi(string userName)
{
// Implement your external API call here
return true;
}
}
Register Your Custom SignInManager
In your Web module, replace the default SignInManager with your custom one:
PreConfigure<IdentityBuilder>(identityBuilder =>
{
identityBuilder.AddSignInManager<CustomSignInManager>();
});
Angular UI Integration
The Angular login component will call the backend as usual. Your backend logic (now using the custom SignInManager) will handle the extra steps transparently.
This approach ensures that all login attempts go through your custom logic, allowing you to perform any checks or user provisioning before completing the sign-in.

This issue is commonly related to the underlying SMTP client implementation or resource exhaustion in long-running applications. By default, ABP uses the .NET SmtpClient, which is known to have connection pooling and resource management issues, especially in cloud environments like Azure App Services. Over time, connections may not be released properly, leading to failures in sending emails until the application is restarted.
The ABP documentation strongly recommends using MailKit instead of the default SmtpClient for production scenarios. MailKit is more robust, supports modern protocols, and is less prone to these issues.
What to check and do next:
Volo.Abp.MailKit NuGet package in your host projects.[DependsOn(typeof(AbpMailKitModule))] public class YourModule : AbpModule { public override void ConfigureServices(ServiceConfigurationContext context) { Configure
- Remove or comment out any code that registers `NullEmailSender` or uses the default `SmtpClient`.
2. **Check for Resource Exhaustion**
- Monitor your application logs for exceptions related to sockets, timeouts, or resource limits.
- Ensure your App Service plan has sufficient resources and is not hitting connection or memory limits.
3. **Review Background Job Handling**
- If you use background jobs for email sending, ensure jobs are not piling up due to failures, which can cause further issues.
4. **Test Email Configuration**
- Use the ABP Setting Management UI or configuration files to verify your SMTP settings are correct and up to date.
5. **Restart as a Temporary Workaround**
- While restarting restores functionality, it is not a long-term solution. Migrating to MailKit is the recommended fix.

Before a user is authenticated and a token is issued (i.e., before the /connect/token endpoint is called), the ABP Framework resolves the current tenant using tenant resolvers (such as domain, header, cookie, or query string). However, the ICurrentTenant.Id will only be set if the tenant can be resolved from the incoming request.
During the login process (before the token is issued), if the request does not contain sufficient tenant information (for example, the __tenant header, a tenant-specific subdomain, or a query string parameter), ICurrentTenant.Id will be null. This is by design: the tenant context is established based on the request, not the user credentials.
To ensure ICurrentTenant is set before authentication, you must configure and use a tenant resolver that can extract the tenant from the request (such as domain/subdomain, header, or query string). For example, in a multi-tenant Angular app, the frontend should send the __tenant header or use a tenant-specific subdomain.
If you need to access tenant information during the login process, make sure your frontend provides the tenant identifier in the request, and your backend is configured to resolve it.
Example configuration:
Configure<AbpTenantResolveOptions>(options =>
{
options.AddDomainTenantResolver("{0}.yourdomain.com");
options.AddHeaderTenantResolver();
options.AddCookieTenantResolver();
options.AddQueryStringTenantResolver();
});
ICurrentTenant.Id will remain null until after the user is authenticated and the token is issued.Sources:

To obtain a JWT token from an ABP-based application, you typically use the /connect/token endpoint, which is provided by IdentityServer or OpenIddict in ABP solutions. The endpoint expects a POST request with the appropriate parameters, such as grant_type, client_id, client_secret, username, password, and scope.
Example request (using Resource Owner Password Credentials flow):
POST https://<your-abp-app>/connect/token
Content-Type: application/x-www-form-urlencoded
grant_type=password
&client_id=YourClientId
&client_secret=YourClientSecret
&username=admin
&password=YourPassword
&scope=YourApiScope
Replace the placeholders with your actual values. The response will include an access_token if the credentials are valid.
If you are using a development environment, make sure your API is running and accessible at the specified URL. Also, ensure that the client is configured in your IdentityServer/OpenIddict settings.

To resolve this:
Check Redirect URI Configuration
https://your-app.azurewebsites.net/swagger/oauth2-redirect.html, this exact URI must be registered as a valid redirect URI for the Swagger client.Update Client Settings
DbMigrator's appsettings.json and/or in your database (OpenIddict/IdentityServer client table) to include the correct redirect URI.Remove Client Secret for Swagger
Restart Services
Verify with Correct URL
Example configuration for Swagger client in appsettings.json:
"Swagger": {
"ClientId": "YourApp_Swagger",
"RootUrl": "https://your-app.azurewebsites.net"
}
And in your client seeding logic:
await CreateClientAsync(
name: "YourApp_Swagger",
grantTypes: new[] { "authorization_code" },
requireClientSecret: false,
redirectUri: "https://your-app.azurewebsites.net/swagger/oauth2-redirect.html",
corsOrigins: new[] { "https://your-app.azurewebsites.net" }
);
If you still encounter issues, double-check that the redirect URI in the error message matches exactly with what is registered.

Since you are using the new ABP Global Assets bundling system for Blazor WASM, and your logs confirm that both FontAwesome and Bootstrap Icons CSS files are being bundled and minified, the most common cause for icons not displaying (showing as empty squares or boxes) is that the font files themselves are not being copied or served correctly.
In ABP's new bundling system, CSS files that reference fonts (like FontAwesome or Bootstrap Icons) use relative URLs to load font files (e.g., .woff2, .ttf). If these font files are not present in the output (wwwroot/_content/...) or not mapped correctly, the icons will not render.
To resolve this, ensure the following:
If the font files are missing, you may need to update your abp.resourcemapping.js or ensure your nuget packages are up to date and not excluded from publish.
You can also try running abp install-libs to ensure all static assets are copied.
If you have custom BundleContributors, make sure you are not only adding the CSS files but also ensuring the font folders are included in the output.
Finally, clear your browser cache or do a hard refresh to ensure old/broken font files are not cached.
This approach aligns with common ABP conventions, but specific official documentation for this exact scenario is not available.
