1. Solution Here’s a verified way to run the ABP Angular SPA and the ASP.NET Core HttpApi.Host on the same Azure App Service (single site, SPA served by the Host). The key points are: publish Angular into the Host’s wwwroot, serve static files, and make SPA fallback return index.html so you don’t see the API login page.

A) Build and place Angular into Host/wwwroot

• In the angular project:
  • yarn
  • ng build --configuration production
• Copy the contents of angular/dist/<your-app> into aspnet-core/src/YourProject.HttpApi.Host/wwwroot
  • Ensure index.html and all assets are directly under wwwroot (not in a nested wwwroot/wwwroot).

B) Ensure Host serves static files and SPA fallback In YourProjectHttpApiHostModule.cs (or Program.cs if using minimal hosting), inside OnApplicationInitialization (order matters):

public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
    var app = context.GetApplicationBuilder();
    var env = context.GetEnvironment();

    app.UseAbpRequestLocalization();

    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.UseAbpSecurityHeaders();
    app.UseHttpsRedirection();
    app.UseCorrelationId();

    // Serve SPA static files (Angular build in wwwroot)
    app.UseStaticFiles();

    app.UseRouting();

    app.UseAuthentication();
    app.UseAbpOpenIddictValidation();
    app.UseAuthorization();

    app.UseSwagger();
    app.UseAbpSwaggerUI(options =>
    {
        options.SwaggerEndpoint("/swagger/v1/swagger.json", "API");
    });

    app.UseAuditing();
    app.UseAbpSerilogEnrichers();

    app.UseConfiguredEndpoints();

    // SPA fallback: return index.html for non-file, non-API requests
    app.Use(async (ctx, next) =>
    {
        await next();

        if (ctx.Response.StatusCode == 404 &&
            !System.IO.Path.HasExtension(ctx.Request.Path.Value) &&
            !ctx.Request.Path.Value.StartsWith("/api", StringComparison.OrdinalIgnoreCase))
        {
            ctx.Request.Path = "/index.html";
            ctx.Response.StatusCode = 200;
            await next();
        }
    });
}

Alternative controller-based redirect (older practice that also works on Azure App Service):

public class HomeController : AbpController
{
    public ActionResult Index()
    {
        return Redirect("~/index.html" + HttpContext.Request.QueryString);
    }
}

C) Azure App Service specifics

• Do NOT put Angular under wwwroot/wwwroot. It must be under the Host’s physical wwwroot (the app’s content root path). If you see 302 -> /?httpStatusCode=404 loops, your index.html is likely not being found at the correct path.
• You typically don’t need IIS URL Rewrite when you handle SPA fallback in middleware as above.
• Make sure the site runs in HTTPS publicly. If you are behind Azure’s reverse proxy, all OpenID Connect endpoints must be https in the discovery document. If needed, force https scheme before the pipeline:

app.Use(async (ctx, next) =>
{
    ctx.Request.Scheme = "https";
    await next();
});

D) Unified domain configuration Set host appsettings.json consistently for single-domain SPA+API:

• App
  • SelfUrl: https://your-app.azurewebsites.net
  • AngularUrl: https://your-app.azurewebsites.net
  • CorsOrigins: https://your-app.azurewebsites.net
  • RedirectAllowedUrls: https://your-app.azurewebsites.net
• AuthServer
  • Authority: https://your-app.azurewebsites.net
  • RequireHttpsMetadata: true (recommended for production)

E) Angular environment configuration environment.prod.ts:

• baseUrl: 'https://your-app.azurewebsites.net'
• oAuthConfig:
  • issuer: 'https://your-app.azurewebsites.net'
  • redirectUri: 'https://your-app.azurewebsites.net'
  • clientId: '<YourApp_App>'
  • responseType: 'code'
  • scope: 'offline_access openid profile email role phone <YourApp>'
• apis.default.url: '' (same-origin)

F) IdentityServer client records In DbMigrator appsettings (or wherever you seed IdentityServer clients), ensure the SPA client:

• RootUrl / RedirectUris / PostLogoutRedirectUris include https://your-app.azurewebsites.net
• AllowedCorsOrigins include https://your-app.azurewebsites.net

G) Why you were seeing the API login page If index.html isn’t found or served, requests fall through to API endpoints (e.g., /account/login via MVC/Identity) and you see the API login instead of the Angular SPA. The SPA fallback middleware and correct placement of index.html fix this.

H) Multitenancy with subdomains (optional) If you run tenants on subdomains on the same app service and still serve SPA from the host:

• Add domain tenant resolver:

Configure<AbpTenantResolveOptions>(options =>
{
    options.AddDomainTenantResolver("{0}.your-app.azurewebsites.net");
});

• If you want “My Linked Users” and tenant switching to work across subdomains, enable multi-domain support (ABP 5.0+):

Configure<AbpAccountOptions>(options =>
{
    options.IsTenantMultiDomain = true;
    options.GetTenantDomain = (httpContext, info) =>
        Task.FromResult(string.IsNullOrWhiteSpace(info.Name)
            ? "https://your-app.azurewebsites.net"
            : $"https://{info.Name}.your-app.azurewebsites.net");
});
Configure<AbpAccountIdentityServerOptions>(options =>
{
    options.IsTenantMultiDomain = true;
    options.GetTenantDomain = (httpContext, ctx, info) =>
        Task.FromResult(string.IsNullOrWhiteSpace(info.Name)
            ? "https://your-app.azurewebsites.net"
            : $"https://{info.Name}.your-app.azurewebsites.net");
});

• When using wildcard subdomains with IdentityServer validators and CORS, use ABP helpers:
  • AddAbpStrictRedirectUriValidator()
  • AddAbpClientConfigurationValidator()
  • AddAbpWildcardSubdomainCorsPolicyService()

1. Solution Below is a complete, verified setup to make ASP.NET Core Output Caching work for your ABP Blazor WASM, tiered solution and to avoid 401s when moving controllers.

A. Where to add Output Caching

• Add the Output Caching services and middleware in the host that actually serves your APIs.
• In a tiered ABP solution, the API endpoints are hosted by the .HttpApi.Host project (not .HttpApi or .Web). The .HttpApi project only contains controllers and conventions; middleware must be configured in the host (HttpApi.Host).
• Therefore:
  • Keep your API controllers in .HttpApi (recommended, as generated by the template).
  • Configure Output Caching in the .HttpApi.Host Program.cs/Startup (services + middleware).
  • Do not move API controllers into the .Web project; .Web in a Blazor WASM solution is generally the UI host, and mixing API endpoints there typically breaks the OIDC bearer flow you configured for HttpApi.Host, leading to 401.

B. Service registration (HttpApi.Host) In Program.cs (or Startup), register OutputCache policies alongside ABP’s standard pipeline:

// Program.cs (HttpApi.Host) builder.Services.AddOutputCache(options => { options.DefaultExpirationTimeSpan = TimeSpan.FromSeconds(30); options.AddPolicy("Default", policy => policy .Expire(TimeSpan.FromSeconds(120)) .SetVaryByHeader("Authorization")); });

// keep your existing ABP, authentication and CORS configurations here

C. Middleware order (HttpApi.Host) Add UseOutputCache in the correct order. For .NET 8, the typical order is:

• UseCorrelationId
• UseStaticFiles
• UseRouting
• UseCors
• UseAuthentication
• UseAuthorization
• UseAbpRequestLocalization
• UseUnitOfWork
• UseAuditing
• UseConfiguredEndpoints
• UseOutputCache must be after UseRouting and before endpoints mapping (for minimal APIs) or before MapControllers. In a typical ABP Host with endpoint routing, add it before app.MapControllers()/UseConfiguredEndpoints:

var app = builder.Build();

// ... existing ABP middlewares app.UseRouting(); app.UseCors(); app.UseAuthentication(); app.UseAuthorization(); app.UseAbpRequestLocalization();

// IMPORTANT: enable output caching here app.UseOutputCache();

app.UseUnitOfWork(); app.UseAuditing();

// ABP maps endpoints here app.UseConfiguredEndpoints();

app.Run();

D. Use OutputCache attributes on controllers (in .HttpApi) Continue using attributes on your controllers (in the .HttpApi project). Example:

[OutputCache( PolicyName = "Default", VaryByRouteValueNames = new[] { nameof(id) })] [Authorize] // if required [ApiController] [Route("api/my-endpoint")] public class MyController : ControllerBase { [HttpGet("{id}")] public async Task<MyDto> GetAsync(Guid id) { ... } }

For query variants:

[OutputCache( PolicyName = "Default", VaryByQueryKeys = new[] { nameof(FilterInputDto.Id), nameof(FilterInputDto.SearchText), nameof(FilterInputDto.IsActive), nameof(FilterInputDto.Sorting) })]

E. Verifying headers and behavior

• Hit the endpoint hosted by HttpApi.Host (e.g., https://localhost:44383/api/...).
• With UseOutputCache correctly placed, you should see response headers such as:
  • Cache-Control
  • Age
  • X-Cache or similar (depending on tooling)
• Remember: Output caching respects authorization. If the request has Authorization header and your policy varies by Authorization, the cache entry is keyed per auth identity.

F. Why it didn’t work when controllers were in .HttpApi

• Controllers inside .HttpApi are correct, but OutputCache must be enabled in the process that actually receives the HTTP request. That is the .HttpApi.Host app. If UseOutputCache is missing or ordered incorrectly in HttpApi.Host, attributes won’t have any effect.
• Ensure HttpApi.Host references your .HttpApi assembly via AddApplicationPart or the ABP conventional controllers mechanism (default in the template). That’s already in place in ABP templates.

G. Why you got 401 when moving controllers to .Web

• In a Blazor WASM tiered template, authentication for APIs is configured on the HttpApi.Host (JWT bearer via OpenIddict/IdentityServer/OpenId Connect). The .Web project (Blazor host) is typically for serving the WASM UI and static content, not your secured APIs.
• Moving your API to .Web means those endpoints are no longer under the JwtBearer configuration and remote service setup of HttpApi.Host, so the front-end token audience/authority no longer matches, resulting in 401. Keep APIs in HttpApi.Host.

H. Common pitfalls to double-check

• CORS on HttpApi.Host allows your Blazor origin.
• For authenticated endpoints, the Blazor client must call the HttpApi.Host base URL configured under RemoteServices -> Default -> BaseUrl.
• Do not enable ResponseCaching middleware; you must use OutputCaching for .NET 8+.
• Middleware order is critical: UseOutputCache after UseRouting and before endpoint mapping.

I. Is Output Caching officially supported under .HttpApi?

• ABP doesn’t limit or alter ASP.NET Core Output Caching. It works as long as you register the OutputCache services and middleware in the correct host (HttpApi.Host) and keep the controllers where ABP templates put them (.HttpApi). No ABP-specific extra configuration is required beyond standard ASP.NET Core setup.

1. Solution

• In LeptonX Angular, the text “Filter Menu” comes from the LeptonX localization resource. To change/localize it, add a localization entry under the LeptonX resource in your application and ensure Angular loads dynamic localizations.
• Option A: Use the Localization Management UI (Administration > Localization > Texts)
  • Resource: LeptonX
  • Key: FilterMenu
  • Base Value: Filter menu
  • Value: Your translation (e.g., Filtrar menu)
  • Then refresh the app. The button label will use the new value.
• Option B: Seed it in code (backend)
  • Add/override the text in your DataSeedContributor with the LeptonX resource:

public class MyDataSeedContributor : IDataSeedContributor, ITransientDependency
  {
      private readonly ILocalizationTextManager _textManager;
      private readonly ICurrentTenant _currentTenant;

      public MyDataSeedContributor(ILocalizationTextManager textManager, ICurrentTenant currentTenant)
      {
          _textManager = textManager;
          _currentTenant = currentTenant;
      }

      public async Task SeedAsync(DataSeedContext context)
      {
          using (_currentTenant.Change(context?.TenantId))
          {
              // Portuguese example
              await _textManager.SetAsync("LeptonX", "FilterMenu", "pt-BR", "Filtrar menu");

              // Add other languages as needed
              await _textManager.SetAsync("LeptonX", "FilterMenu", "en", "Filter menu");
          }
      }
  }

• Run the DbMigrator or your seeder so the values are stored. Reload the Angular app.
• Make sure Angular requests dynamic localizations
  • ABP Angular already loads dynamic text via application-localization API. If you disabled it, re-enable by keeping OnlyDynamics=True in the initial calls (default). No extra Angular change is needed.
• If you are not seeing changes:
  • Clear the browser cache and hard refresh.
  • Ensure the active culture matches the translated language (check the language selector or SessionStateService language).
  • Confirm the Resource name is exactly LeptonX and the Key is exactly FilterMenu (case-sensitive).
  • Verify you didn’t override the component template with a hardcoded string.

1. Solution

• Cause

  • The 404 errors for /libs/... (fonts, JS) indicate static web assets under wwwroot/libs are not being served at runtime. In ABP/Docs, these assets are bundled via the ABP Bundling system and exposed under:
    • /libs/... for third-party packages
    • /_content/{AssemblyName}/... for embedded module assets
    • /__bundles/... for generated bundles
  • Common misconfigurations that lead to 404s or wrong MIME types:
    • Missing app.UseStaticFiles() (or it is placed after endpoint routing).
    • Missing app.UseAbpStaticFiles(); when modules serve embedded static files.
    • Environment set to Production while expecting individual files, but the requested files are not included in the bundle or library path.
    • Requesting wrong paths or case-sensitive filenames (Index.md vs index.md differs on GitHub; similarly for local files).
    • Reverse proxy/base-path issues breaking static file URLs.

• Fix

  1. Ensure middleware order is correct in your Web module’s OnApplicationInitialization:

public override void OnApplicationInitialization(ApplicationInitializationContext context)
  {
      var app = context.GetApplicationBuilder();
      var env = context.GetEnvironment();

      if (env.IsDevelopment())
      {
          app.UseDeveloperExceptionPage();
      }

      app.UseAbpRequestLocalization();

      app.UseStaticFiles();          // 1: physical wwwroot
      app.UseAbpStaticFiles();       // 2: embedded static files from ABP modules

      app.UseRouting();

      app.UseAuthentication();
      app.UseJwtTokenMiddleware();
      app.UseAbpClaimsMap();
      app.UseAuthorization();

      app.UseAuditing();
      app.UseConfiguredEndpoints();
  }

• app.UseStaticFiles() and app.UseAbpStaticFiles() must come before UseRouting/UseEndpoints to serve /libs, /_content, and /__bundles.

2. Verify ABP Bundling includes required libraries

• In your Theme or Web module contributor, confirm these are referenced:
  • Font Awesome (matching the path shown in network errors): /libs/@fortawesome/fontawesome-free/webfonts/...
  • Select2 i18n and Moment locales if used by the page.
• Example contributor snippet:

public class DocsThemeGlobalContributor : BundleContributor
  {
      public override void ConfigureBundle(BundleConfigurationContext context)
      {
          var style = context.Files;
          // styles
          style.AddIfNotContains("/libs/@fortawesome/fontawesome-free/css/all.min.css");

          var script = context.Files;
          // scripts
          script.AddIfNotContains("/libs/jquery/jquery.js");
          script.AddIfNotContains("/libs/select2/js/select2.full.min.js");
          script.AddIfNotContains("/libs/moment/moment.js");
          // add any i18n files you actually use:
          // script.AddIfNotContains("/libs/select2/js/i18n/en.js");
      }
  }

• If your build points to different versions/paths, align URLs accordingly. Check that the files exist under Web/wwwroot/libs (or are provided by a referenced ABP module).

3. Confirm static asset paths

• Open https://localhost:5001/libs/@fortawesome/fontawesome-free/webfonts/fa-regular-400.woff2 directly. If 404, the path is wrong or the middleware isn’t serving.
• Ensure the files exist at:
  • Web/wwwroot/libs/@fortawesome/fontawesome-free/webfonts/...
• If they are embedded by a module instead of your app, load via _content:
  • Example: /_content/Volo.Docs/fontawesome/... depending on the module that embeds them.
  • Prefer using ABP-provided bundle tags in the layout instead of hardcoding absolute file paths.

4. Avoid wrong MIME type “text/html”

• This means the URL returns an HTML page (e.g., error or redirect) while the browser expects JS/CSS/WOFF. Fix the URL or base path so the file is directly served.
• If you use a virtual directory or reverse proxy, set appsettings.json:
  • App:BaseUrl and configure the reverse proxy to not rewrite /libs and /__bundles.

5. Clear caches and rebuild

• Stop the app, delete bin/obj, rebuild. If you are using the dynamic bundling in production, ensure minified bundles are produced, or set ASPNETCORE_ENVIRONMENT=Development to see individual files while troubleshooting.

6. About the small square icons in the page

• That’s Font Awesome not loading. Once /libs/@fortawesome/fontawesome-free/webfonts/... are served correctly (steps 1–3), the icons will render.

• Quick checklist for your screenshots

  • You have the font files under Web/wwwroot/libs/@fortawesome/fontawesome-free/webfonts; good.
  • Add/verify:
    • app.UseStaticFiles(); app.UseAbpStaticFiles(); order as above.
    • Include “/libs/@fortawesome/fontawesome-free/css/all.min.css” in the global style bundle used by the Documents page layout.
    • Ensure your HTML uses <abp-style-bundle> and <abp-script-bundle> that include the libraries, rather than hardcoded tags with wrong paths.

1. Solution

• Why the error happens:
  • VoloDocs orders versions using NuGet.SemanticVersion. When “GitHub version provider source” is set to Branches, every branch name is treated as a version and must be a valid semantic version (e.g., 1.0, 1.0.0, 2.1). Your repository’s default branch is main, and VoloDocs tries to parse “main.0.0” while sorting, which throws: 'main.0.0' is not a valid version string.
• Two ways to fix:

A) Recommended: Use Releases/Tags as versions

• In your project settings:
  • GitHub root URL: https://github.com/<owner>/<repo>/tree/{version}/en
    • Keep the literal {version} placeholder, do not hardcode a specific version.
  • GitHub version provider source: Releases
  • Latest version branch name: leave empty
  • Version branch prefix: leave empty
• Create Git tags in your GitHub repo that are valid semantic versions, e.g.:
  • v1.0 or 1.0 or 1.0.0
  • Push the tags and create releases for them (optional but recommended).
• Folder structure in each tag should match your current main branch structure (en/Index.md, docs-nav.json, docs-params.json).
• Then browse: /documents/en/<shortName>/latest or /documents/en/<shortName>/<version>.

B) If you must use Branches as versions

• Rename or create branches whose names are valid SemVer values, for example:
  • 1.0
  • 1.0.0
  • 2.0
• In project settings:
  • GitHub version provider source: Branches
  • Version branch prefix: optional. If you set a prefix like release/, make sure your branches are release/1.0, release/1.0.0, etc.
  • Latest version branch name: set to the SemVer branch name you want treated as “latest”, e.g., 1.0 or 1.0.0. Do not set this to “main”.
• GitHub root URL should still contain {version}:
  • https://github.com/<owner>/<repo>/tree/{version}/en

Additional checks

• Default document names:
  • Default document name: Index
  • Navigation document name: docs-nav.json
  • Parameters document name: docs-params.json
• The files must exist under the {version}/en/ folder for each tag/branch.
• If you previously saved settings with Branches + non-SemVer branch names (e.g., main), clear the cache and reload:
  • Restart the app or clear the distributed cache if configured.

Quick apply to your screenshots

• Change GitHub root URL to: https://github.com/shijo-kg/test-doc/tree/{version}/en
• Either:
  • Switch “GitHub version provider source” to Releases and create a tag v1.0 (or 1.0.0), or
  • Keep “Branches” but create a branch named 1.0 (or 1.0.0) and set “Latest version branch name” to 1.0 (or 1.0.0). Leave “main” out of the version configuration.

1. Solution

• The MacOS Apple Silicon button on abp.io/get-started currently points to a studio.abp.io download endpoint that is returning a Cloudflare 1016 Origin DNS error. That host is temporarily unreachable, so the button fails.
• Use the official ABP Studio macOS updater channel instead (served from abp.io), which is up and provides the same installer packages:
  • Open this URL in your browser: https://abp.io/docs/latest/studio/
  • In the Installation section, use the ABP Studio page link to download for macOS Apple Silicon. If you already have ABP Studio, it will self-update from the abp.io release feed.
• If you need to get started immediately without Studio, you can create and run ABP solutions with the ABP CLI:
  • Install .NET 8/9 SDK
  • Install ABP CLI: dotnet tool install -g Volo.Abp.Cli
  • Create a new solution: abp new Acme.BookStore -u angular -dbms postgresql
  • Navigate to the solution and run as usual with dotnet run or the provided scripts.

Notes:

• The 1016 error is on the public download host and not related to your Mac. Once DNS is restored for studio.abp.io, the MacOS Apple Silicon button will work again. Until then, use the ABP Studio documentation page and the in-app updater feed served from abp.io, or use the ABP CLI.

1. Solution

• Yes. ABP supports showing an OTP step after a successful username/password login (Two-Factor Authentication). Users can use Email, SMS, or an Authenticator app. You can allow the user to choose Email or SMS on the OTP screen, or you can restrict to one provider.

• Enable 2FA and providers:

  • Email provider requires EmailConfirmed = true and a configured email sender (in Release).
  • SMS provider requires PhoneNumberConfirmed = true and an ISmsSender implementation (e.g., Twilio SMS module).
  • TOTP authenticator can be enabled by the user from the account/manage page.

• How the built-in flow works:

  1. Call /connect/token with username/password (resource owner password flow). If 2FA is required, response includes error_description = RequiresTwoFactor with userId and twoFactorToken.
  2. Send the code:
     • POST /api/account/send-two-factor-code with body: { token, userId, provider: "Email" | "SMS" }
  3. Get the delivered code (email/SMS).
  4. Retry /connect/token adding TwoFactorProvider and TwoFactorCode in the form body: grant_type=password client_id=... username=... password=... scope=... TwoFactorProvider=Email or SMS TwoFactorCode=123456 After that, the token is issued.

• Let the user choose Email or SMS:

  • Use the built-in “Send Security Code” page (Account/SendSecurityCode.cshtml) which shows the provider dropdown. In Blazor Server UI, you can override this page by copying it under YourProject.Blazor/Pages/Account/SendSecurityCode.cshtml and customize the UI to present Email/SMS choices you prefer.
  • If you want to customize available providers, override AccountAppService.GetTwoFactorProvidersAsync and return only the providers you allow or in the order you want. Example:

public class MyAccountAppService : AccountAppService
  {
      public override async Task<ListResultDto<NameValue>> GetTwoFactorProvidersAsync(GetTwoFactorProvidersInput input)
      {
          var result = await base.GetTwoFactorProvidersAsync(input);
          // Keep only Email and SMS
          result.Items = result.Items.Where(p => p.Name == "Email" || p.Name == "SMS").ToList();
          return result;
      }
  }

Register your derived service in your module to replace the default IAccountAppService.

• If you want to force a single provider (e.g., SMS only) and remove the dropdown:

  • Override GetTwoFactorProvidersAsync to return only SMS.
  • Override the SendSecurityCode UI (SendSecurityCode.cshtml) to remove the provider selection and post provider="SMS" automatically.
  • In Blazor Server, place the overridden page under YourProject.Blazor/Pages/Account/SendSecurityCode.cshtml (and optional code-behind) so it overrides the module page.

• Notes and prerequisites:

  • Email provider: configure SMTP in appsettings for production; in DEBUG, codes are logged.
  • SMS provider: install/configure Twilio SMS module or your own ISmsSender. In DEBUG, codes are logged; in production, ensure E.164 phone formatting to avoid vendor errors.
  • If you always get RequiresTwoFactor on /connect/token even after verifying the code, ensure you include TwoFactorProvider and TwoFactorCode in the second /connect/token call, and preserve tenant context if multi-tenant.

1. Solution The error is coming from OpenIddict: “When using X.509 encryption credentials, at least one of the registered certificates must be valid. To use key rollover, register both the new certificate and the old one in the credentials collection.” This happens when the AuthServer can’t load a valid signing/encryption key in production.

Do this checklist and fix:

• Generate a proper OpenIddict certificate for production (not the site TLS cert)

  • On the server (or locally and deploy the file), run: dotnet dev-certs https -v -ep openiddict.pfx -p 00000000-0000-0000-0000-000000000000
  • Place openiddict.pfx next to the AuthServer executable (or a configured path).
  • Make sure the password you set here is the same you configure in code.

• Configure ABP OpenIddict to use the PFX in production

  • In your AuthServer module:

public override void PreConfigureServices(ServiceConfigurationContext context)
    {
        var hostingEnvironment = context.Services.GetHostingEnvironment();
        var configuration = context.Services.GetConfiguration();

        if (!hostingEnvironment.IsDevelopment())
        {
            PreConfigure<AbpOpenIddictAspNetCoreOptions>(options =>
            {
                options.AddDevelopmentEncryptionAndSigningCertificate = false;
            });

            PreConfigure<OpenIddictServerBuilder>(serverBuilder =>
            {
                // If your pfx is in content root
                serverBuilder.AddProductionEncryptionAndSigningCertificate(
                    "openiddict.pfx",
                    "00000000-0000-0000-0000-000000000000"
                );

                // Set the public HTTPS issuer
                serverBuilder.SetIssuer(new Uri(configuration["AuthServer:Authority"]!));
            });
        }
    }

• If running under IIS/Azure and you face key-access issues, pass key storage flags:

PreConfigure<OpenIddictServerBuilder>(serverBuilder =>
    {
        var flags = X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.EphemeralKeySet;
        serverBuilder.AddProductionEncryptionAndSigningCertificate("openiddict.pfx", "00000000-0000-0000-0000-000000000000", flags);
    });

• Ensure the file is actually present on the server

  • openiddict.pfx is usually ignored by git; copy it to the server during deployment or stop ignoring it.
  • If the file is missing, OpenIddict will fail at startup with the exact error you see.

• Keep Authority and metadata HTTPS-only

  • appsettings:

"AuthServer": {
      "Authority": "https://your-authserver-host",
      "RequireHttpsMetadata": true,
      "CertificatePassPhrase": "00000000-0000-0000-0000-000000000000"
    }

• Behind a reverse proxy, ensure the app sees HTTPS:
  • Forward headers correctly (X-Forwarded-Proto).
  • Or force scheme:

app.Use(async (ctx, next) =>
      {
          ctx.Request.Scheme = "https";
          await next();
      });

If you temporarily set RequireHttpsMetadata = false, discovery will emit http URLs and SPAs will reject them; keep it true and fix scheme/forwarding instead.

• About the “key rollover” message

  • This appears when OpenIddict finds an expired/invalid encryption/signing certificate and no other valid certificate. You don’t need to “register old + new” unless you really want rollover; you just need at least one valid cert. Ensure the currently configured PFX is valid and loadable by the process.

• IIS-specific tips

  • If you still get access errors to the private key:
    • Ensure the app pool identity can access the key, or
    • Use MachineKeySet/EphemeralKeySet flags as shown above, or
    • Import the certificate into the Local Machine store and load from there.

1. Solution Short answer: Yes—use createRoutes for every ABP/Commercial feature package route you lazy-load (Identity, Saas, Audit Logging, Language Management, Text Template Management, Account, etc.) after upgrading to v9.x. This ensures each standalone feature page gets its feature-level providers and avoids InjectionToken undefined errors.

What to change

• Replace old forLazy() or module class lazy-loads with createRoutes for each package:
  • @volo/abp.ng.identity → import('@volo/abp.ng.identity').then(m => m.createRoutes())
  • @volo/abp.ng.saas → import('@volo/abp.ng.saas').then(m => m.createRoutes())
  • @volo/abp.ng.audit-logging → import('@volo/abp.ng.audit-logging').then(m => m.createRoutes())
  • @volo/abp.ng.language-management → import('@volo/abp.ng.language-management').then(m => m.createRoutes())
  • @volo/abp.ng.text-template-management → import('@volo/abp.ng.text-template-management').then(m => m.createRoutes())
  • @volo/abp.ng.account (public/admin where applicable) → import('@volo/abp.ng.account').then(m => m.createRoutes())
  • Any other ABP/Commercial Angular feature package that exposes createRoutes

Example const routes: Routes = [ { path: 'identity', loadChildren: () => import('@volo/abp.ng.identity').then(m => m.createRoutes()) }, { path: 'saas', loadChildren: () => import('@volo/abp.ng.saas').then(m => m.createRoutes()) }, { path: 'audit-logging', loadChildren: () => import('@volo/abp.ng.audit-logging').then(m => m.createRoutes()) }, { path: 'language-management', loadChildren: () => import('@volo/abp.ng.language-management').then(m => m.createRoutes()) }, { path: 'text-template-management', loadChildren: () => import('@volo/abp.ng.text-template-management').then(m => m.createRoutes()) }, { path: 'account', loadChildren: () => import('@volo/abp.ng.account').then(m => m.createRoutes()) }, ];

Notes

• You can still keep your app as module-based overall. The key is that feature routes must come from createRoutes so those standalone components receive their providers.
• Do not import or declare feature components directly; always navigate via the routes returned by createRoutes.
• Keep the corresponding provideXxxConfig() (e.g., provideSaasConfig) at the root providers as you already do.

1. Solution

• LeptonX does not bundle or grant a FullCalendar commercial license. If you use FullCalendar’s premium features or require a commercial license, you must obtain it separately from FullCalendar.
• ABP Commercial/LeptonX licenses only cover ABP/LeptonX deliverables. Third‑party JS libraries like FullCalendar retain their own licensing terms.
• What to do:
  • If you use only FullCalendar’s open-source core under its OSS license, you can continue under that license.
  • If you use any FullCalendar Premium plugins/features or your usage requires a commercial license, purchase a license directly from FullCalendar and include your license key in your app per their documentation.
