  hi

  This seems to be a problem with https://github.com/Azure/azure-signalr.

  But you can try the code below to fix it.

  app.UseAuthorization();
  
  app.Use(async (httpContext, next) =>
  {
      var authenticateResultFeature = httpContext.Features.Get<IAuthenticateResultFeature>();
      if (authenticateResultFeature != null && authenticateResultFeature.AuthenticateResult == null)
      {
          if (httpContext.User.Identity?.IsAuthenticated == true)
          {
              authenticateResultFeature.AuthenticateResult = AuthenticateResult.Success(new AuthenticationTicket(httpContext.User, httpContext.User.Identity.AuthenticationType!));
          }
      }
  
      await next(httpContext);
  });
  
  app.UseSwagger();

  Getting this error after implementing as suggested.

  This exception was originally thrown at this call stack: [External Code] AzureSignalRPoc.Blazor.AzureSignalRPocBlazorModule.OnApplicationInitialization.AnonymousMethod__16_0(Microsoft.AspNetCore.Http.HttpContext, Microsoft.AspNetCore.Http.RequestDelegate) in AzureSignalRPocBlazorModule.cs

  public override void OnApplicationInitialization(ApplicationInitializationContext context)
  {
      var env = context.GetEnvironment();
      var app = context.GetApplicationBuilder();
  
      if (env.IsDevelopment())
      {
          app.UseDeveloperExceptionPage();
      }
  
      app.UseAbpRequestLocalization();
  
      if (!env.IsDevelopment())

  hi

  Please change your OnApplicationInitialization method by follow:

  public override void OnApplicationInitialization(ApplicationInitializationContext context)
  {
      var env = context.GetEnvironment();
      var app = context.GetApplicationBuilder();
  
      if (env.IsDevelopment())
      {
          app.UseDeveloperExceptionPage();
      }
  
      app.UseAbpRequestLocalization();
  
      if (!env.IsDevelopment())
      {
          app.UseErrorPage();
          app.UseHsts();
      }
  
      app.UseCorrelationId();
      app.UseAbpSecurityHeaders();
      app.UseStaticFiles();
      app.UseRouting();
      app.UseAuthentication();
      app.UseAbpOpenIddictValidation();
  
      if (MultiTenancyConsts.IsEnabled)
      {
          app.UseMultiTenancy();
      }
  
      app.UseUnitOfWork();
      app.UseDynamicClaims();
      app.UseAuthorization();
  
      app.Use(async (httpContext, next) =>
      {
          var authenticateResultFeature = httpContext.Features.Get<IAuthenticateResultFeature>();
          if (authenticateResultFeature != null && authenticateResultFeature.AuthenticateResult == null)
          {
              if (httpContext.User.Identity?.IsAuthenticated == true)
              {
                  authenticateResultFeature.AuthenticateResult = AuthenticateResult.Success(new AuthenticationTicket(httpContext.User, httpContext.User.Identity.AuthenticationType!));
              }
          }
  
          await next(httpContext);
      });
  
      app.UseSwagger();
      app.UseAbpSwaggerUI(options =>
      {
          options.SwaggerEndpoint("/swagger/v1/swagger.json", "AzureSignalRPoc API");

  Hi maliming,

  That last change you suggested was the solution. Everything appears to be working now.

  Right now I have that code in OnApplicationInitialization and these settings in appsettings.json

  "Azure": { "SignalR": { "Enabled": "true" } }

  { "Azure:SignalR:ConnectionString": "Endpoint=https://xxxxxxx.service.signalr.net;AccessKey=xxxxxxxxxx=;Version=1.0;" }
