1. Solution

• Root cause

  • In Blazor Web App, menus are built on the server first, then the client (WASM-side) re-hydrates and re-evaluates feature/permission requirements using values coming from the Application Configuration endpoint. If your custom feature definitions are not exposed to the client, RequireFeatures(...) will hide items after client load.
  • Features are only sent to the client if each feature definition:
    • Belongs to a registered Feature Group, and
    • Is visible to clients (IsVisibleToClients = true), and
    • The FeatureDefinitionProvider is discovered in the running app (module dependency path).

• What to do

  1. Ensure your FeatureDefinition is visible to clients

public class SaasFeaturesDefinitionProvider : FeatureDefinitionProvider
  {
      public override void Define(IFeatureDefinitionContext context)
      {
          var group = context.GetGroupOrNull(ModulesFeatures.Main)
                     ?? context.AddGroup(ModulesFeatures.Main, L("MainFeatures"));

          group.AddFeature(
              SaasFeatures.Saas,
              defaultValue: "true",
              displayName: L(SaasFeatures.Saas),
              isVisibleToClients: true // <<< important
          );
      }

      private static LocalizableString L(string name)
          => LocalizableString.Create<PlatformResource>("Features:" + name);
  }

2. Make sure the Feature Group exists in the same Define call path

• If your ModulesFeatures.Main group is defined in a shared NuGet, ensure that group is created before adding features. If not already created in that package, add it as shown above with context.AddGroup(...).

3. Verify the module dependency path so the provider is discovered

• The assembly that contains SaasFeaturesDefinitionProvider must be referenced and its module must be depended on by the application:

[DependsOn(
      typeof(AbpFeaturesModule)
      // + your package/module that contains the FeatureDefinitionProvider
  )]
  public class PlatformDomainModule : AbpModule
  {
  }

• Ensure the package is referenced by the final app (HttpApi.Host for server, and the Blazor project if it needs types). The provider must be in a module that is part of the server app’s module graph so the server can define and expose features.

4. Do not mark the feature as not visible later

• Avoid setting IsVisibleToClients = false anywhere via options or additional providers.

5. Confirm from the client that the feature is delivered

• After the above changes, the application-configuration response should include your feature under features.values.
• If it still doesn’t appear, clear caches and ensure you’ve run the migrator and restarted the app.

6. Using RequireFeatures on the menu

• With the feature now visible to clients, the item will remain visible after client load:

var saas = context.Menu.GetMenuItem(SaasHostMenus.GroupName);
  saas.RequireFeatures(SaasFeatures.Saas);

7. Notes on defaultValue and database values

• defaultValue: "true" is used only if there is no stored value. If you manage the feature in UI, the database value takes precedence.

• Ensure the tenant/host you are testing has the feature enabled in the Features modal.

• Quick checklist

  • [ ] Feature group exists (context.AddGroup or previously defined).
  • [ ] AddFeature(... isVisibleToClients: true).
  • [ ] Provider assembly is loaded and module is in dependency chain.
  • [ ] application-configuration features.values contains your key.
  • [ ] Menu item uses RequireFeatures with the correct full feature name.

2. Sources

• Features basics and client visibility:
  • https://github.com/abpframework/abp (project source reference)
  • This approach aligns with the official “Features” documentation statement: “A feature value is available at the client side too, unless you set IsVisibleToClients to false on the feature definition.”

1. Solution To get a bearer access token for a tenant user using Postman (for ABP 8.x with separated Auth Server/OpenIddict), use the standard OAuth2/OpenID Connect token endpoint. Then you can reuse the same token in JMeter.

Follow these steps:

• Determine your Auth Server base URL

  • For separated AuthServer in Angular solutions, it’s typically like: https://localhost:44322
  • The discovery document shows exact endpoints at: https://localhost:44322/.well-known/openid-configuration
  • The token endpoint will be: https://localhost:44322/connect/token

• Create or confirm a client that allows the password flow

  • In your Auth Server’s data seed (or via UI), ensure a client exists that supports:
    • grant_types: password (Resource Owner Password)
    • allowed scopes: openid, profile, email, phone, roles, offline_access plus your API scopes (e.g., YourProjectName)
    • If required, set ClientSecret and RequireClientSecret accordingly.
  • If you don’t have a password-enabled client, you can alternatively use the Authorization Code flow in Postman’s OAuth2 helper, but for automation/password-based login you need the password grant configured.

• Postman request to get the token (password grant)

  • Method: POST
  • URL: https://localhost:44322/connect/token
  • Headers:
    • Content-Type: application/x-www-form-urlencoded
    • For multi-tenancy, add: Abp-TenantId: <tenant-guid> (or use the tenant-specific host if you use domain/subdomain tenant resolution)
      • If your app uses subdomains per tenant (e.g., https://tenant1.yoursite.com), you don’t need Abp-TenantId; use the tenant host to reach the same token endpoint domain.
  • Body (x-www-form-urlencoded):
    • grant_type: password
    • username: <tenant-user-username-or-email>
    • password: <tenant-user-password>
    • client_id: <your-client-id>
    • client_secret: <your-client-secret> (if the client requires a secret)
    • scope: openid profile email phone roles offline_access <YourApiScope1> <YourApiScope2>
  • Send. The response contains access_token, token_type, expires_in, and optionally refresh_token.

• Important multi-tenancy notes

  • If your solution uses header/cookie based tenancy (not domain-based), include either:
    • Abp-TenantId header with the tenant’s Id, or
    • X-Tenant (older patterns) if you customized it.
  • If you use domain/subdomain based tenancy, call the token endpoint on the tenant domain so OpenIddict issues a token for that tenant context.
  • Don’t rely on /account/login for API tokens. It’s cookie-based and will interfere with Postman. Always use /connect/token for bearer tokens.
  • If you previously called /account/login in Postman, clear cookies before calling /connect/token (cookies can cause 400/CSRF or wrong flow). In Postman, open Cookies for the domain and remove them.

• Use the token in JMeter

  • Take the access_token value and set an HTTP Header Manager with:
    • Authorization: Bearer <access_token>
    • For multi-tenancy (if not domain-based), also add Abp-TenantId: <tenant-guid>
  • Optionally, automate token retrieval in JMeter with a pre-HTTP sampler that posts to /connect/token and saves access_token to a JMeter variable for subsequent samplers.

• Example curl (equivalent to Postman) curl -X POST "https://localhost:44322/connect/token" ^ -H "Content-Type: application/x-www-form-urlencoded" ^ -H "Abp-TenantId: 11111111-1111-1111-1111-111111111111" ^ --data-urlencode "grant_type=password" ^ --data-urlencode "username=admin@mytenant.com" ^ --data-urlencode "password=1q2w3E*" ^ --data-urlencode "client_id=MyAngular_App" ^ --data-urlencode "client_secret=1q2w3e*" ^ --data-urlencode "scope=openid profile email roles offline_access MyProjectName"

If you prefer client credentials (app-to-app, no user), use:

• grant_type: client_credentials
• Remove username/password
• Keep client_id, client_secret, and scopes for your APIs
• Still include Abp-TenantId if your service access must be tenant-scoped.

2. Sources

• OpenIddict token flow examples and usage in ABP community articles (password flow and token acquisition were demonstrated and discussed across support threads and samples). No single official page precisely documents Postman steps for tenant tokens, but this approach aligns with ABP’s OpenIddict usage and is consistent with official guidance to use /connect/token rather than cookie-based endpoints.

1. Solution

• Recommended approach: Resolve the tenant using a standard tenant resolver (domain/subdomain, route, header, or query string) instead of deriving it from client_id. ABP’s multi-tenancy pipeline is designed to determine the current tenant before MVC/OpenIddict endpoints run. Tying tenant selection to client_id is brittle (one client may serve multiple tenants; client names can change; it bypasses ABP’s resolvers). Prefer:

  • Subdomain/domain resolver (e.g., https://nextjs.yoursite.com)
  • Route resolver (e.g., https://yoursite.com/nextjs/Account/Register)
  • Query string or header (e.g., __tenant=NextJs)

• If you still want to implement a client_id-to-tenant mapping: add a custom ITenantResolveContributor that checks the request when OpenIddict’s authorize/login/register endpoints are hit and sets the tenant from a mapping dictionary. Ensure you register it very early in the resolver pipeline and only apply it for the authorize/login/register paths, so you don’t affect other requests.

Code: Domain/route (recommended)

• Domain/subdomain resolver:

// In YourProjectNameHttpApiHostModule (or AuthServer module if separated)
  using Volo.Abp.MultiTenancy;

  public override void ConfigureServices(ServiceConfigurationContext context)
  {
      var configuration = context.Services.GetConfiguration();

      Configure<AbpTenantResolveOptions>(options =>
      {
          // Example: https://{0}.yourdomain.com
          options.AddDomainTenantResolver("{0}.yourdomain.com");
      });
  }

• Route resolver:
  • Add {__tenant} to the Account pages/routes or globally, then the authorize/login flows will carry the tenant in the route and ABP will resolve it automatically. See the community article technique to add a route convention if you want it globally.

Code: Custom contributor mapping client_id -> tenant (if you must)

using System.Threading.Tasks;
  using Microsoft.AspNetCore.Http;
  using Microsoft.Extensions.Primitives;
  using Volo.Abp.DependencyInjection;
  using Volo.Abp.MultiTenancy;

  public class ClientIdTenantResolveContributor : HttpTenantResolveContributorBase, ITransientDependency
  {
      public const string ContributorName = "ClientIdTenant";
      public override string Name => ContributorName;

      protected override Task<string?> GetTenantIdOrNameFromHttpContextOrNullAsync(
          ITenantResolveContext context, HttpContext httpContext)
      {
          // Only act on OIDC endpoints to avoid side effects
          var path = httpContext.Request.Path.Value ?? "";
          if (!path.StartsWith("/connect/authorize") &&
              !path.StartsWith("/Account/Login") &&
              !path.StartsWith("/Account/Register"))
          {
              return Task.FromResult<string?>(null);
          }

          // Read client_id from query (OpenIddict authorize request)
          if (httpContext.Request.Query.TryGetValue("client_id", out StringValues clientIds))
          {
              var clientId = clientIds.ToString();

              // Your mapping: client_id => tenant name
              // Example: Next_app => "NextJs"
              var tenantName = MapClientIdToTenantName(clientId);
              if (!tenantName.IsNullOrWhiteSpace())
              {
                  return Task.FromResult<string?>(tenantName);
              }
          }

          return Task.FromResult<string?>(null);
      }

      private static string? MapClientIdToTenantName(string clientId)
      {
          return clientId switch
          {
              "Next_app" => "NextJs",
              // add other mappings here
              _ => null
          };
      }
  }

Register it early in the pipeline (before others that you want it to override):

public override void ConfigureServices(ServiceConfigurationContext context)
  {
      Configure<AbpTenantResolveOptions>(options =>
      {
          // Put it at the beginning if you want it to take precedence
          options.TenantResolvers.Insert(0, new ClientIdTenantResolveContributor());
      });
  }

• Notes and caveats:
  • client_id can be reused by multiple tenants in many deployments; mapping it to a single tenant may force the wrong tenant.
  • If you adopt domain or route resolver, the Account UI will already know the tenant, and OpenIddict authorize will honor it consistently.
  • For Angular/Next.js SPAs, also ensure your frontend sends the tenant via domain or adds __tenant in the query/header automatically. For Angular, navigateToLogin can accept __tenant; for custom Next.js redirects you can include __tenant in the authorize URL if you use query-string tenant resolver.

1. Solution

• What you see is expected for ABP 10.0.0 at the moment. ABP 10 targets .NET/EF Core 10, and the Npgsql EF Core provider published a matching 10.0.0-rc1 package when ABP 10.0.0 shipped. Therefore, Volo.Abp.EntityFrameworkCore.PostgreSql brings Npgsql.EntityFrameworkCore.PostgreSQL 10.0.0-rc1 transitively.
• This produces build warnings but is safe to use. When Npgsql releases the stable 10.0.0 provider, ABP will align its dependency to the stable version in a patch release.

Workarounds you can apply today:

• Suppress prerelease warning noise and stay on the transitive version (recommended until ABP bumps):

  • No action needed; continue building and running.

• Force the stable provider version when it becomes available:

  • Add an explicit PackageReference in your csproj to pin the provider:

<ItemGroup>
    <PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="10.0.0" />
  </ItemGroup>

This overrides the transitive rc1 from Volo.Abp.EntityFrameworkCore.PostgreSql.

• If you prefer to stay fully stable right now, use ABP 9.3.x (EF Core 9) with Npgsql EF Core 9.x, or wait for the next ABP 10 patch that updates to the stable Npgsql 10.

1. Solution

• Default choice and design reason

  • In ABP, IGuidGenerator.Create() is intended to avoid Guid.NewGuid() and provide DB-friendly GUIDs. The official guideline explicitly says “never use Guid.NewGuid() to create Ids” and recommends sequential GUIDs for performance on clustered indexes. ABP’s infrastructure documentation states that IGuidGenerator creates sequential GUIDs and that SequentialGuidGenerator is the default. If you’re seeing SimpleGuidGenerator.Instance in a DomainService, that indicates a local override or a custom registration, not the ABP default behavior. The design goal is: by default, ABP uses a sequential generator to reduce fragmentation and improve insert performance on relational databases.

• Downsides or caveats of using sequential GUIDs globally

  • Sequential GUIDs are designed to be monotonically increasing (in a DB-appropriate way) to reduce index fragmentation on clustered PKs. They are generally favorable for SQL Server clustered indexes compared to random GUIDs. Potential caveats:
    • Predictability: IDs roughly encode creation order. If you consider that sensitive, it’s a trade-off.
    • Cross-database ordering differences: Sequential GUID strategies differ by provider (e.g., SQL Server uses SequentialAtEnd style). ABP’s sequential generator handles this so it’s not typically a problem, but be aware IDs won’t be strictly comparable across providers if you mix them.
    • No known distributed-system uniqueness downside: They remain 128-bit GUIDs and are safe for distributed generation. There’s no distributed-system uniqueness penalty compared to random GUIDs.

• How to replace the default with SequentialGuidGenerator via DI (ABP-idiomatic)

  • If your app somehow resolved to SimpleGuidGenerator, override the registration in your module:

using Microsoft.Extensions.DependencyInjection;
    using Volo.Abp;
    using Volo.Abp.Guids;

    public class MyModule : AbpModule
    {
        public override void ConfigureServices(ServiceConfigurationContext context)
        {
            context.Services.AddSingleton<IGuidGenerator, SequentialGuidGenerator>();
        }
    }

• This forces the sequential implementation globally. In an ABP app with standard EF Core provider packages, this is normally unnecessary because ABP already wires SequentialGuidGenerator as the default.

• Is ABP’s SequentialGuidGenerator recommended for production with large datasets and GUID PKs?

  • Yes. This is the documented recommendation specifically to mitigate heavy insert fragmentation on clustered indexes when using GUID PKs. For SQL Server, this is the preferred approach vs. Guid.NewGuid(). It is production-ready and the recommended default.

1. Solution You’re right: there is no public “LeptonXThemeUiOptions” for MVC. The supported, documented way to hard‑force Light (and avoid client/OS overrides) on LeptonX MVC is to override the style provider.

Implement a custom provider by inheriting the built-in LeptonXStyleProvider and override only what you need (SelectedStyle, Side menu, etc.). Then register it as the ILeptonXStyleProvider.

Example (MVC, ABP v9.x):

using System.Threading.Tasks;
using Microsoft.Extensions.Options;
using Volo.Abp.DependencyInjection;
using Volo.Abp.Ui.LeptonX;
using Volo.Abp.Ui.LeptonX.Theming;

namespace Tapp.Web;

// Inherit the base provider to avoid re-implementing unrelated members
public class TappLeptonXStyleProvider : LeptonXStyleProvider, ITransientDependency
{
    public TappLeptonXStyleProvider(IOptions<LeptonXThemeOptions> options)
        : base(options)
    {
    }

    // Force Light theme always
    public override Task<string> GetSelectedStyleAsync()
    {
        return Task.FromResult(LeptonXStyleNames.Light);
    }

    // Optional: keep menu expanded (example)
    public override Task<LeptonXSideMenuState> GetSideMenuStateAsync()
    {
        return Task.FromResult(LeptonXSideMenuState.Expanded);
    }
}

Register it in your WebModule so it replaces the default provider:

using Microsoft.Extensions.DependencyInjection;
using Volo.Abp.Modularity;
using Volo.Abp.Ui.LeptonX.Theming;

[DependsOn(typeof(AbpAspNetCoreMvcUiLeptonXThemeModule))] // ensure LeptonX MVC module is depended
public class TappWebModule : AbpModule
{
    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        context.Services.AddTransient<ILeptonXStyleProvider, TappLeptonXStyleProvider>();
    }
}

Notes:

• Inheriting LeptonXStyleProvider ensures you don’t have to guess other members or future additions; you only override what you need. This is exactly why you saw “Please inherit the LeptonXStyleProvider base class.”
• Clear browser storage/cookies or test in a private window if you previously switched to dark; client persistence can trick you during tests.
• If you’ve added any toolbar/theme-switch UI, remove it so the client can’t toggle styles.

1. Solution To force Light theme only (disable Dark) in an MVC app that uses LeptonX/LeptonX Lite (ABP v9.3):

• Set the default style to Light on the server (so initial render is Light)
  • In your Web module (e.g., YourProject.WebModule), configure LeptonX theme options:

using Volo.Abp.Ui.Branding;
  using Volo.Abp.AspNetCore.Mvc.UI.Theme.LeptonXLite; // or LeptonX, depending on your package
  using Volo.Abp.AspNetCore.Mvc.UI.Theme.LeptonXLite.Bundling; // if using LeptonX Lite bundles
  using Volo.Abp.AspNetCore.Mvc.UI.Theme.Shared;

  public override void ConfigureServices(ServiceConfigurationContext context)
  {
      Configure<LeptonXThemeOptions>(options =>
      {
          // Forces default style to Light
          options.DefaultStyle = LeptonXThemeStyle.Light;
      });

      // Optional: if you have per-user style/cookie preferences lingering from development,
      // you can disable reading from user settings to avoid OS/system overrides:
      Configure<LeptonXThemeUiOptions>(ui =>
      {
          ui.AllowStyleSelectionFromClient = false;
      });
  }

• Remove or hide the client-side theme switcher

  • If you have a toolbar item/view component or script that toggles theme, remove it from the toolbar contributors and layout.
  • Ensure you don’t include any JS that calls ThemeService/setTheme (for Angular) or injects a body class to switch styles on the client.

• Clear persisted client preference so testing doesn’t revert to Dark

  • LeptonX may remember the last selected style via local storage or cookies. Clear browser storage/cookies and test in a private/incognito window to confirm the forced Light style takes effect.

• Prevent system/OS dark preference from applying

  • Ensure your layout doesn’t include scripts that auto-select “System” style or apply [prefers-color-scheme: dark] behavior.
  • With AllowStyleSelectionFromClient = false and DefaultStyle = Light, the server will always render Light and the client won’t override it.

• If you still see dark colors, verify CSS order

  • Make sure no custom CSS/JS or additional theme bundles re-apply dark classes after render.
  • Check that only the Light variant of LeptonX CSS is being applied at runtime (remove any dynamic theme-loader scripts if you added them manually).

Code-only minimal variant:

public override void ConfigureServices(ServiceConfigurationContext context)
{
    Configure<LeptonXThemeOptions>(options =>
    {
        options.DefaultStyle = LeptonXThemeStyle.Light;
    });

    Configure<LeptonXThemeUiOptions>(ui =>
    {
        ui.AllowStyleSelectionFromClient = false;
    });
}
