1. Solution Your error comes from OpenIddict rejecting the redirect_uri used by the Hangfire Dashboard OIDC challenge in your remote environment. In Kubernetes (and when services are split behind gateways/ingress), the actual callback URL that the browser hits often differs from the value you seeded for the client. You must ensure that every possible redirect URI used by the Hangfire site is registered for the Hangfire client in OpenIddict, and that you request a redirect URI that exactly matches one of them.

Do all of the following:

• Register every real redirect URI used by Hangfire in the remote environment:

  • If users access Hangfire via an ingress/gateway (e.g., https://treva-hangfire.tav.aero), add:
    • https://treva-hangfire.tav.aero/signin-oidc
    • If you also allow access via gateway/edge or different hostnames/ports, add all of them:
      • https://treva-web.tav.aero/signin-oidc
      • https://treva-webgateway.tav.aero/signin-oidc
      • https://treva-authserver.tav.aero/signin-oidc
  • Do the same for Post Logout Redirect URIs:
    • https://treva-hangfire.tav.aero/signout-callback-oidc
    • https://treva-web.tav.aero/signout-callback-oidc
    • https://treva-webgateway.tav.aero/signout-callback-oidc
    • https://treva-authserver.tav.aero/signout-callback-oidc

• Seed the Hangfire OpenIddict client with those exact values (seed order doesn’t matter, but strings must match 1:1 with what the browser will use):

await CreateOrUpdateApplicationAsync(
      name: "Hangfire",
      type: OpenIddictConstants.ClientTypes.Confidential,
      consentType: OpenIddictConstants.ConsentTypes.Implicit,
      displayName: "Hangfire Client",
      secret: "1q2w3e*",
      grantTypes:
      [
          OpenIddictConstants.GrantTypes.AuthorizationCode,
          OpenIddictConstants.GrantTypes.ClientCredentials,
          OpenIddictConstants.GrantTypes.RefreshToken,
          // Remove Password & Implicit unless you really need them; not required for server-side MVC OIDC
          "pushed_authorization"
      ],
      scopes:
      [
          OpenIddictConstants.Scopes.OpenId,
          OpenIddictConstants.Scopes.Profile,
          OpenIddictConstants.Scopes.Email,
          OpenIddictConstants.Scopes.Phone,
          OpenIddictConstants.Scopes.OfflineAccess,
          "roles",
          "HangfireService"
      ],
      redirectUris:
      [
          "https://treva-hangfire.tav.aero/signin-oidc",
          "https://treva-web.tav.aero/signin-oidc",
          "https://treva-webgateway.tav.aero/signin-oidc",
          "https://treva-authserver.tav.aero/signin-oidc"
      ],
      postLogoutRedirectUris:
      [
          "https://treva-hangfire.tav.aero/signout-callback-oidc",
          "https://treva-web.tav.aero/signout-callback-oidc",
          "https://treva-webgateway.tav.aero/signout-callback-oidc",
          "https://treva-authserver.tav.aero/signout-callback-oidc"
      ]
  );

• Ensure the Hangfire Dashboard app challenges with the same authority and callback path:

  • In Hangfire service (MVC), your OpenIdConnect defaults already use CallbackPath = "/signin-oidc" by convention. Do not override to something else unless you also update the client’s redirect URIs.
  • If you are building your redirect using a root URL, make sure webClientRootUrl resolves to the public URL that the browser uses to reach the Hangfire Dashboard in Kubernetes (the ingress hostname), not an internal service name or localhost.

• If you enabled PAR (pushed_authorization):

  • Keep the client’s “Allow pushed authorization endpoint” checked and include "pushed_authorization" in extension grant types.
  • Make sure the request’s redirect_uri still exactly matches a registered URI. PAR doesn’t relax redirect_uri matching.

• Clear caches after seeding:

  • If you use Redis/DataProtection caching for OpenIddict validation, clear Redis and restart the AuthServer so it reloads client definitions.

• Common pitfalls to avoid:

  • Do not point Hangfire to webClientRootUrl of your main web app unless the signin-oidc callback really returns to the main web app and you’ve registered that URI for the Hangfire client.
  • Don’t mix HTTP/HTTPS. If ingress terminates TLS and you use HTTPS outside, register HTTPS URIs.
  • If you changed ports/hosts between local and remote, update the client’s redirect URIs accordingly.
  • Prefer removing “password” and “implicit” grant types for a confidential server-side MVC client; use authorization_code (+ PKCE if you prefer) with refresh_token.

• Verify

  • Open the AuthServer /.well-known/openid-configuration on the public URL to ensure the browser is using the same authority as your OpenIdConnect handler.
  • Attempt login; if it fails, check AuthServer logs for “Client validation failed because '…/signin-oidc' was not a valid redirect_uri” and compare the exact string with your database values.

1. Solution

• Using the preview modules
  • Install and enable:
    • Add Volo.Abp.AI and Volo.Abp.AI.Management packages to your solution and add the corresponding module dependencies in your module classes.
    • Configure an IChatClient via Microsoft.Extensions.AI in your web (or application) module. ABP’s AI infrastructure is designed to work with Microsoft.Extensions.AI abstractions.
    • Example minimal setup (OpenAI shown as a reference provider):

using Microsoft.Extensions.AI;
      using OpenAI;

      [DependsOn(
          typeof(AbpAIModule),          // AI infrastructure
          typeof(AiManagementModule)    // AI Management module
      )]
      public class MyProjectWebModule : AbpModule
      {
          public override void ConfigureServices(ServiceConfigurationContext context)
          {
              var configuration = context.Services.GetConfiguration();

              context.Services.AddSingleton(new OpenAIClient(configuration["AI:OpenAI:Key"]));

              context.Services.AddChatClient(services =>
                  services.GetRequiredService<OpenAIClient>()
                          .AsChatClient(configuration["AI:OpenAI:Chat:ModelId"] ?? "gpt-4o-mini"));
          }
      }

- appsettings.json example:

{
        "AI": {
          "OpenAI": {
            "Key": "YOUR-KEY",
            "Chat": { "ModelId": "gpt-4o-mini" }
          }
        }
      }

• Current limitations to be aware of (preview):

  • Provider coverage is driven by Microsoft.Extensions.AI integrations; features vary per provider (e.g., tool/function calling, images, embeddings). Ensure the chosen provider supports your required capabilities.
  • The AI Management module is evolving: management UI and orchestration features are being expanded; some scenarios may be incomplete in preview.
  • Expect changes while in preview; validate your configuration and keep packages in sync with the related ABP version.

• Roadmap / planning

  • The modules are in preview; ABP aims to build on Microsoft.Extensions.AI and add management, configuration, and orchestration capabilities on top. Some features (like deeper agent/orchestration support and richer management UI) are planned and rolling out. While abstractions are intended to be stable, preview implies there may be breaking changes. Follow the docs/changelogs for updates as versions progress from preview to stable.

• Custom chat client calling an external API (AI agents)

  • Yes, you can plug a custom chat client using ConfigureChatClient/AddChatClient. The recommended way is to implement Microsoft.Extensions.AI.IChatClient (or adapt an existing client) and register it, so the rest of ABP AI infrastructure and AI Management can use it like built-in providers.
  • Minimal example: forwarding to an arbitrary HTTP endpoint

using System.Net.Http;
    using System.Net.Http.Json;
    using System.Threading;
    using System.Threading.Tasks;
    using Microsoft.Extensions.AI;

    public sealed class HttpForwardingChatClient : IChatClient
    {
        private readonly HttpClient _http;
        private readonly string _endpoint; // e.g. https://customer-api.example.com/agent/chat

        public HttpForwardingChatClient(HttpClient http, string endpoint)
        {
            _http = http;
            _endpoint = endpoint;
        }

        public async Task<ChatCompletion> CompleteAsync(
            ChatMessage message,
            ChatOptions options = null,
            CancellationToken cancellationToken = default)
        {
            var payload = new
            {
                input = message.Text,
                // optionally map options (system prompt, temperature, tools, etc.)
            };

            var response = await _http.PostAsJsonAsync(_endpoint, payload, cancellationToken);
            response.EnsureSuccessStatusCode();
            var result = await response.Content.ReadFromJsonAsync<ExternalResponse>(cancellationToken: cancellationToken);

            return new ChatCompletion(new ChatMessage(Role.Assistant, result?.Output ?? string.Empty));
        }

        // Implement other IChatClient members if needed by your use-cases (e.g., streaming)
        private sealed class ExternalResponse
        {
            public string Output { get; set; }
        }
    }

Registering the custom client with ABP AI:

[DependsOn(typeof(AbpAIModule), typeof(AiManagementModule))]
      public class MyProjectWebModule : AbpModule
      {
          public override void ConfigureServices(ServiceConfigurationContext context)
          {
              var configuration = context.Services.GetConfiguration();
              context.Services.AddHttpClient<HttpForwardingChatClient>(client =>
              {
                  client.BaseAddress = new Uri(configuration["AI:ExternalAgent:BaseUrl"]);
              });

              context.Services.AddChatClient(sp =>
                  sp.GetRequiredService<HttpForwardingChatClient>());
          }
      }

After registration, you can inject IChatClient anywhere (app services, pages, components) and AI Management can treat it similarly to built-in providers, as the integration point is the same abstraction (IChatClient). If your scenario requires streaming, tools/functions, or multi-turn context, implement the corresponding members or map the needed options to your external API.

1. Solution

• Background

  • RequireFeatures on a permission definition hides that permission when the required feature is disabled for the current tenant. Host has no tenant context; if the feature you reference is not enabled for the Host side, all children (menu items bound to those permissions) disappear for Host admins.
  • StateCheckers allow custom enable/disable logic per permission (e.g., “bypass for host, check feature for tenants”), but they only affect the permission state. If your Angular menus are not also filtered by permission/feature, a menu item can still render and then fail with 403 when navigated.
  • In microservice + Angular, menu visibility depends on:
    • The permission attached to the menu item (requiredPolicy in Angular).
    • Feature checks (optional) you apply in the menu contributor.
    • The actual grant rows in PermissionGrants for the current user/role/tenant.

• Part A: Host admin can still see “Management Service” when RequireFeatures is used

  1. Ensure features are enabled for Host if you want Host to see these permissions.
     • In the Feature Management UI, switch to Host side and enable the features required by your permissions (e.g., CarbonFeatures.Categories, CarbonFeatures.CategoryTypes, etc.). If you manage features programmatically, set default values for the host:

public class CarbonFeatureDefinitionProvider : FeatureDefinitionProvider
     {
         public override void Define(IFeatureDefinitionContext context)
         {
             var group = context.AddGroup("CarbonFeatures");
             group.AddFeature("CarbonFeatures.Categories", defaultValue: "true"); // host-default
             group.AddFeature("CarbonFeatures.Categories.Create", defaultValue: "true");
             group.AddFeature("CarbonFeatures.Categories.Edit", defaultValue: "true");
             group.AddFeature("CarbonFeatures.Categories.Delete", defaultValue: "true");

             group.AddFeature("CarbonFeatures.CategoryTypes", defaultValue: "true");
             group.AddFeature("CarbonFeatures.CategoryTypes.Create", defaultValue: "true");
             group.AddFeature("CarbonFeatures.CategoryTypes.Edit", defaultValue: "true");
             group.AddFeature("CarbonFeatures.CategoryTypes.Delete", defaultValue: "true");
         }
     }

2. Alternatively, keep RequireFeatures for tenants, but bypass feature checks for host via StateCheckers:

public sealed class HostBypassFeatureChecker : ISimpleStateChecker<PermissionDefinition>
     {
         public async Task<bool> IsEnabledAsync(SimpleStateCheckerContext<PermissionDefinition> context)
         {
             var currentTenant = context.ServiceProvider.GetRequiredService<ICurrentTenant>();
             if (!currentTenant.IsAvailable) // Host
                 return true;

             var featureChecker = context.ServiceProvider.GetRequiredService<IFeatureChecker>();
             // Map permission name to feature name as you need
             var featureName = MapPermissionToFeature(context.State.Name);
             return await featureChecker.IsEnabledAsync(featureName);
         }

         private static string MapPermissionToFeature(string permissionName)
         {
             // Example mapping: adjust to your permission constants
             if (permissionName.StartsWith(ManagementServicePermissions.Categories.Default))
                 return "CarbonFeatures.Categories";
             if (permissionName.StartsWith(ManagementServicePermissions.CategoryTypes.Default))
                 return "CarbonFeatures.CategoryTypes";
             return permissionName; // fallback
         }
     }
     // Apply to your permission definitions:
     var category = myGroup.AddPermission(ManagementServicePermissions.Categories.Default, L("Permission:Categories"));
     category.StateCheckers.Add(new HostBypassFeatureChecker());

 This approach keeps the Host menu visible without requiring Host features to be explicitly enabled.

• Part B: Prevent tenants from seeing menu pages that are not included in their package
  • Root cause in your scenario: the Angular menu item appears because the permission used by the menu item is granted (or no permission was bound to the menu item). Clicking leads to 403 because the page or API requires a different permission that is not granted.
  • Fixes:
    1. Ensure each Angular route/menu item uses a permission that exactly matches your backend permission for that page. Do not use a “broader” parent permission if you want to hide the page when a sub-feature is disabled.
       • Angular route guard:

{
           path: 'category-types',
           component: CategoryTypesComponent,
           canActivate: [PermissionGuard],
           data: { requiredPolicy: 'ManagementService.CategoryTypes' }
         }

   - Menu item:

this.context.addItem({
           id: 'ManagementService.CategoryTypes',
           text: 'Category Types',
           icon: 'fa fa-list',
           order: 10,
           requiredPolicy: 'ManagementService.CategoryTypes'
         }, MANAGEMENT_MENU_NAME);

   - If you need feature-level hiding too, add a feature check in the menu contributor and skip adding the item when feature is disabled for the current tenant.
2) Do not grant the permission in the tenant’s package if the page must be hidden. If you are generating grants dynamically, verify PermissionGrant table has no rows for the excluded pages. Your observation is correct: once the grants are removed, the menu is hidden provided you use requiredPolicy on the menu item.
3) If you keep using StateCheckers (bypass for host, check feature for tenant), keep menu items bound to those exact permissions. Since ABP UI reads permission states, menu entries disappear for tenants when the feature is disabled.
4) For microservice solutions with dynamic permissions: verify the PermissionDefinition names you bind in Angular match the definitions pushed by that microservice. A mismatch leads to menu items always visible due to missing policy binding.

• Part C: Known edge cases and recommendations

  • Use RequireFeatures on permission definitions only if you also want menus and API access to follow the same feature switches. If host must always see, either enable those features for Host or switch to StateCheckers that bypass for host.
  • In Angular, always set both:
    • canActivate PermissionGuard on routes.
    • requiredPolicy on menu items. This guarantees no “visible but 403 on click” inconsistency.
  • If you need a package concept: treat the package assignment flow as feature/permission provisioning. When a package is assigned to a tenant, grant only the permissions of included pages. When a package excludes a page, ensure those permissions are not granted. Use your provisioning service to synchronize PermissionGrant records accordingly.

• Minimal example putting all together

  • Permission definitions:

public class ManagementServicePermissionDefinitionProvider : PermissionDefinitionProvider
  {
      public override void Define(IPermissionDefinitionContext context)
      {
          var group = context.AddGroup("ManagementService");

          var categories = group.AddPermission("ManagementService.Categories", L("Permission:Categories"));
          categories.StateCheckers.Add(new HostBypassFeatureChecker()); // host bypass
          categories.RequireFeatures("CarbonFeatures.Categories");      // tenant feature

          var categoryTypes = group.AddPermission("ManagementService.CategoryTypes", L("Permission:CategoryTypes"));
          categoryTypes.StateCheckers.Add(new HostBypassFeatureChecker());
          categoryTypes.RequireFeatures("CarbonFeatures.CategoryTypes");
      }
  }

• Angular route and menu:

// route
  { path: 'categories', component: CategoriesComponent, canActivate: [PermissionGuard], data: { requiredPolicy: 'ManagementService.Categories' } }
  { path: 'category-types', component: CategoryTypesComponent, canActivate: [PermissionGuard], data: { requiredPolicy: 'ManagementService.CategoryTypes' } }

  // menu
  this.context.addItem({
    id: 'ManagementService',
    text: 'ManagementService',
    icon: 'fa fa-book',
    order: 30
  });

  this.context.addItem({
    id: 'ManagementService.Categories',
    text: 'Categories',
    parentId: 'ManagementService',
    requiredPolicy: 'ManagementService.Categories'
  });

  this.context.addItem({
    id: 'ManagementService.CategoryTypes',
    text: 'Category Types',
    parentId: 'ManagementService',
    requiredPolicy: 'ManagementService.CategoryTypes'
  });

• Feature defaults for host (optional) if you prefer RequireFeatures without StateChecker bypass:

public class CarbonFeatureDefinitionProvider : FeatureDefinitionProvider
  {
      public override void Define(IFeatureDefinitionContext context)
      {
          var g = context.AddGroup("CarbonFeatures");
          g.AddFeature("CarbonFeatures.Categories", defaultValue: "true");
          g.AddFeature("CarbonFeatures.CategoryTypes", defaultValue: "true");
      }
  }

This approach will:

• Make Host admin always see and access Management Service (via host-bypass or enabling host features).
• Make tenants see only the pages included in the package because only those permissions will be granted and the menu items require those permissions; excluded pages won’t appear at all, avoiding the 403-on-click experience.

1. Solution

• Cause: CMS Kit Blog pages ship their own Bootstrap container/row markup and some generic CSS. In LeptonX for Blazor, the application body already uses a flex/grid layout and spacing utilities. When the blog list and post components render inside the layout, duplicated container/row wrappers and a few global CSS classes from the Blog module can break the page width and push the sidebar/header out of alignment.

• Fix 1 — Update LeptonX and CMS Kit to the latest compatible versions for ABP 9.3.x:

  • Ensure all UI packages are aligned to your ABP version (9.3.6). Mismatched minor versions easily cause layout glitches.
  • In all Blazor UI projects, align these packages:
    • Volo.Abp.AspNetCore.Components.Web.LeptonXTheme
    • Volo.CmsKit.Pro.Public.Web and Volo.CmsKit.Pro.Admin.Web (or the non-Pro equivalents if you use the open-source CMS Kit)
  • After updating, clean and rebuild.

• Fix 2 — Remove conflicting container wrappers in your CMS Kit page overrides:

  • If you customized/overrode any Blog razor components (List or Detail) under your project (e.g., Pages/CmsKit/Blogs/* or Components/Blogs/*), remove extra Bootstrap container/row/col wrappers. LeptonX already handles the main container. Keep only the content block.
  • Example (pseudo-diff):

<!-- Before -->
    <div class="container">
      <div class="row">
        <div class="col-12">
          @* Blog content *@
        </div>
      </div>
    </div>

    <!-- After -->
    @* Use LeptonX content area; no extra container *@
    @* Blog content *@

• Fix 3 — Ensure you’re not importing Blog CSS globally:

  • If you added custom blog CSS to wwwroot/styles.css or imported a third-party blog stylesheet globally, scope it to the blog components only, or remove global selectors that target html/body/.container/.row. Use a wrapper class (e.g., .blog-page) in the blog components and prefix selectors accordingly.

• Fix 4 — Verify LeptonX app layout and content container:

  • Make sure your MainLayout is using the default LeptonX layout and that your content is placed inside the provided content area. Avoid adding additional wrappers with fixed widths.
  • If you replaced any LeptonX layout component (Header, Footer, ContentContainer), revert to the default or re-implement with the same structure to preserve the layout.

• Fix 5 — Clear cached assets:

  • Delete bin/obj, purge wwwroot (generated bundles), and restart the app. If you use static versioning, increment the bundle version so browsers fetch the new CSS.

1. Solution

• Reason: The client (Login/Register/ChangePassword pages) adds its own validators. If you lower Identity password requirements on the server (e.g., RequiredLength = 3), but the UI still shows “min 6” (or other rules), it means the client-side validators are not refreshed or they are hard-coded/defaulted.

• Fix (Angular UI):

  1. Make sure the password rules are coming from the dynamic application configuration and not hard-coded. Update ABP Angular packages to the latest compatible version.
     • Run:
       • yarn upgrade @abp/ng.core @abp/ng.account.core @abp/ng.account @volo/abp.ng.identity.config
       • Delete node_modules and yarn.lock (or package-lock.json) and reinstall.
  2. Ensure the Register/ChangePassword forms use the validators provided by @volo/abp.ng.identity.config (or read them from getApplicationConfiguration) instead of a fixed Validators.minLength(6). Any local form code that sets Validators.minLength(6) must be changed to use the value from configuration (identity.password.requiredLength).
  3. After changing settings at runtime, refresh application configuration so the UI gets new rules. A full page reload always works. In SPA scenarios where you change settings without reload, reinitialize CurrentApplicationConfiguration on the client after saving settings.

• Fix (MVC UI):

  • Remove any hard-coded minlength attributes or model validators that conflict with IdentityOptions and bind to the IOptions<IdentityOptions>.Value.Password.RequiredLength for client validation metadata, or disable conflicting client rules.

• Notes:

  • Server-side validation always uses the backend settings (IdentityOptions). Even if the client lets a weak password through, the server will still reject it if it violates current rules.
  • Historically, mismatches were fixed by updating the identity config package in Angular projects. If you’re on an older version, upgrade the UI packages to align with backend rules.

1. Solution

• You can’t load Lepton (v1) and LeptonX themes at the same time. Both modules register the same keys and services (e.g., AbpErrorPageOptions.ErrorViewUrls["401"], DefaultTheme, toolbar contributors, bundle names), which causes “An item with the same key has already been added” and “service not registered” errors. ABP supports only one active MVC theme per application.

• Pick one theme and remove the other theme module(s) and registrations:

  • If you want LeptonX:
    • Remove AbpAspNetCoreMvcUiLeptonThemeModule from all DependsOn attributes and delete any custom module inheriting from AbpAspNetCoreMvcUiLeptonThemeModule.
    • Add AbpAspNetCoreMvcUiLeptonXThemeModule to your Web module DependsOn.
    • Remove any Configure<AbpErrorPageOptions>() entries you copied from Lepton to avoid duplicate keys; LeptonX already configures these.
    • Ensure you register the theme in AbpThemingOptions only once (DefaultThemeName should be LeptonXTheme.Name or let LeptonX register itself).
    • If you use LeptonX theme management/settings, add Volo.Abp.LeptonXTheme.Management.Domain.Shared to your Domain.Shared project and add [DependsOn(typeof(LeptonXThemeManagementDomainSharedModule))] to your domain shared module.
  • If you want Lepton (v1):
    • Remove AbpAspNetCoreMvcUiLeptonXThemeModule from DependsOn and any LeptonX nuget/package references.
    • Keep AbpAspNetCoreMvcUiLeptonThemeModule and its options.

• Do not inherit one theme module from the other. Theme modules are independent and each configures its own services/options. Inheriting or registering both leads to duplicate option keys and missing service registrations for the “current theme” resolver.

• After changes:

  • Clean and rebuild to ensure only one theme remains:
    • abp clean
    • dotnet restore
    • dotnet build
  • If you switched to LeptonX and see “Undefined setting: Volo.Abp.LeptonXTheme.ApplicationLayout”, add the LeptonX theme management shared module as noted above.

Code example (use LeptonX only):

using Volo.Abp.AspNetCore.Mvc.UI.Theming;
using Volo.Abp.Modularity;
using Volo.Abp.AspNetCore.Mvc.UI.Theme.LeptonX;

[DependsOn(
    typeof(AbpAspNetCoreMvcUiLeptonXThemeModule)
    // remove: typeof(AbpAspNetCoreMvcUiLeptonThemeModule)
)]
public class MyWebModule : AbpModule
{
    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        Configure<AbpThemingOptions>(options =>
        {
            // Don’t add Lepton and LeptonX together
            options.Themes.Add<LeptonXTheme>();
            options.DefaultThemeName = LeptonXTheme.Name;
        });

        // Remove duplicate error page mapping if you had both:
        // Configure<AbpErrorPageOptions>(options => { ... }); // Not needed for LeptonX
    }
}

If you need to switch themes dynamically at runtime, implement a single theme that changes its resources/layouts based on a setting or cookie rather than loading two different theme modules simultaneously.

1. Solution

• Why this happens

  • In LeptonX/LeptonX Lite for Blazor, the login page header uses the Branding component. Its rendering logic is:
    • If LogoUrl is set (not null/empty), it shows only the logo (no AppName text).
    • If LogoUrl is null/empty, it shows the AppName text (and uses a default logo elsewhere if needed).
    • Therefore, when you override LogoUrl, AppName is intentionally hidden.
  • The logo size on the login page is controlled by the theme’s CSS for the Branding component. If your custom asset has extra whitespace or different intrinsic dimensions/aspect ratio, it can appear smaller.

• Keep AppName visible and customize the logo Option A: Use LogoUrl only inside the app shell, not on the login page

  • Override the login page Branding with your own component so you can render both logo and AppName:
    1. Create a custom Branding component override under your Web project to replace the theme’s Branding on the login page:
    • Create file: /Themes/LeptonX/Components/Branding/Default.razor (path must match the theme component to override).
    • Example implementation:

@inject Volo.Abp.Ui.Branding.IBrandingProvider Branding

      <div class="lpx-branding lpx-branding--login">
          <img src="@Branding.LogoUrl" alt="@Branding.AppName" class="lpx-branding__logo" />
          <div class="lpx-branding__title">@Branding.AppName</div>
      </div>

      @code { }

- Add minimal CSS to keep original sizing:
  - Add to wwwroot/global-styles.css (or your bundle):

.lpx-branding--login {
          display: flex;
          flex-direction: column;
          align-items: center;
          gap: .5rem;
        }
        .lpx-branding__logo {
          height: 56px; /* similar to default */
          width: auto;
        }
        .lpx-branding__title {
          font-size: 1.5rem;
          font-weight: 600;
        }

- This ensures both the logo and AppName are shown on login regardless of LogoUrl.

Option B: Do not override LogoUrl; use LeptonX CSS variables

• LeptonX supports logo customization via CSS variables. If you only set:

:root .lpx-theme-light {
      --lpx-logo: url('/images/logo/leptonx/icon-logo.svg');
      --lpx-logo-icon: url('/images/logo/leptonx/icon.svg');
    }
    :root .lpx-theme-dark,
    :root .lpx-theme-dim {
      --lpx-logo: url('/images/logo/leptonx/icon-logo.svg');
      --lpx-logo-icon: url('/images/logo/leptonx/icon.svg');
    }

- Keep DefaultBrandingProvider.LogoUrl = null (do not override), and keep AppName override as desired:

[Dependency(ReplaceServices = true)]
      public class AbpTabsBrandingProvider : DefaultBrandingProvider
      {
          public override string AppName => "AbpTest";
          // Do not override LogoUrl -> keep base.LogoUrl (null) so AppName is displayed
      }

- The theme will use your CSS-defined logos in the layout while still showing AppName on the login page.

• Keep the logo size consistent
  • Ensure your SVG has a proper viewBox and no excessive whitespace.
  • Control size with CSS in your override or by targeting the default selector:

/* If not overriding component, target default branding image on login */
    .lpx-auth .lpx-branding img, 
    .lpx-auth .lpx-branding svg {
      height: 56px;
      width: auto;
    }

• If your asset is small intrinsically, set a consistent height in CSS as above.

• Per-tenant branding

  • If you need tenant-specific logos:
    • Keep the override in BrandingProvider, but move tenant logic into CSS variables or component override rather than setting LogoUrl. You can:
      • Use settings per tenant to change CSS variables via a Layout Hook or a small style tag injected at runtime.
      • Or override the Branding component and compute the URL per tenant, while still rendering AppName alongside the image (as in Option A).

• Summary of what to change

  1. Remove your override of LogoUrl (to show AppName again), and switch to LeptonX CSS variables for logos; or
  2. Keep LogoUrl override and override the Branding component for the login page to render both the image and AppName; and
  3. Add CSS to enforce a consistent logo height (e.g., 56px) on the login page.

1. Solution

• Root cause: In ABP v9.2+ Angular UI packages were migrated to standalone. If your app still uses NgModule-based components, ABP Angular elements like abp-button (emitting abpClick) and abp-modal (content projection, submit wiring) will only work if their standalone imports/providers are added to your module (or component) explicitly. Using (click) works because it’s plain Angular, but abpClick is an ABP output from the ButtonComponent and requires importing the ABP button component/directives into the module where it’s used.

• Fix: Import the ABP Angular standalone components into your module via the provided module-level re-export (for non-standalone apps), or import the components directly in a standalone component’s imports.

For a non-standalone component declared in an NgModule:

// app.module.ts (or a feature module where your modal component is declared)
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
// Bring ABP Angular shared directives/components into module-based apps:
import { AbpThemeSharedModule } from '@abp/ng.theme.shared'; // re-exported compatibility module

import { MyFeatureComponent } from './my-feature.component';

@NgModule({
  declarations: [MyFeatureComponent],
  imports: [
    CommonModule,
    AbpThemeSharedModule, // IMPORTANT: provides abp-button, abp-modal, directives like abpClose, abpPermission, etc.
  ],
})
export class MyFeatureModule {}

If you don’t have AbpThemeSharedModule (depending on version), import the specific components into your module via their modules (compatibility packages) or switch your component to standalone and import the components there:

// my-feature.component.ts (standalone variant)
import { Component } from '@angular/core';
import { ButtonComponent } from '@abp/ng.theme.shared/components/button';
import { ModalComponent } from '@abp/ng.theme.shared/components/modal';

@Component({
  selector: 'app-my-feature',
  standalone: true,
  imports: [ButtonComponent, ModalComponent],
  template: `
    <abp-modal [(visible)]="isOpen">
      <ng-template #abpHeader>Title</ng-template>
      <ng-template #abpBody>Body</ng-template>
      <ng-template #abpFooter>
        <abp-button (abpClick)="onSubmit()">Submit</abp-button>
      </ng-template>
    </abp-modal>
  `,
})
export class MyFeatureComponent {
  isOpen = true;
  onSubmit() { /* ... */ }
}

• Ensure you’re using the ABP button output:

<!-- inside modal footer/body -->
<abp-button (abpClick)="onSubmit()" [buttonType]="'button'">
  Save
</abp-button>

• Double-check that there isn’t an overlay or disabled state blocking clicks:

  • abp-modal’s [busy] input sets the projected abpSubmit button’s loading state and prevents closing; if you set [busy]="true" permanently, clicks may appear ignored. Make sure [busy] is false when you expect interaction.
  • If your footer uses a native button with [disabled], that will bypass abpClick because it won’t fire.

• If you are wiring form submit:

  • Either use form="form-id" with a native button and handle (ngSubmit) on the form, or use abp-button with (abpClick). Mixing disabled states can give the impression of “no click”.

• Summary checklist for module-based app:

  1. Import AbpThemeSharedModule (or the required ABP Angular compatibility modules) in the NgModule that declares the component using abp-modal/abp-button.
  2. Use (abpClick) on abp-button.
  3. Verify [busy] and disabled states aren’t blocking the event.

1. Solution

• ABP 9.x targets .NET 9. The official migration guide states that if you plan to use ABP 9.0, you need to migrate your solutions to .NET 9.0. Therefore, ABP 9.0/9.1 packages (for example, Volo.Saas.Host.Application 9.0.0) are not compatible with net8.0 and will produce NU1202 (exactly like in your screenshot), because those packages include net9.0 TFMs.

• What you can do:

  • Option A (stay on .NET 8): Keep your solution on ABP 8.x (latest 8.3.4) which fully supports .NET 8.
  • Option B (move to ABP 9.x): Upgrade your solution to .NET 9 (update TargetFramework to net9.0 and update Microsoft.* packages to 9.0.0) and then update ABP to 9.x.

• Minimal steps for Option B (upgrade to .NET 9 + ABP 9.x):

  1. Install .NET 9 SDK.
  2. Change all project <TargetFramework> to net9.0 (and update global.json if present).
  3. Upgrade Microsoft.* NuGet packages to 9.0.0.
  4. abp update (to move ABP packages to 9.x).
  5. Apply the ABP 9 migration adjustments (e.g., MapAbpStaticAssets if applicable), as per the guide.

• Why your error happens:

  • The package Volo.Saas.Host.Application 9.0.0 only provides net9.0; your project targets net8.0. NuGet raises NU1202: “not compatible with net8.0”.
