Hi We are trying to connect to azure signalR

and getting these 4 errors:

=>Castle.MicroKernel.ComponentActivator.ComponentActivatorException: 'ComponentActivator: could not instantiate Microsoft.Azure.SignalR.ServiceLifetimeManager`1[[LoadStop.Web.Chat.SignalR.ChatHub, LoadStop.Web.Core, Version=5.0.0.0, Culture=neutral, PublicKeyToken=null]]'

=>Exception: Could not instantiate Microsoft.Azure.SignalR.ServiceLifetimeManager`1[[LoadStop.Web.Chat.SignalR.ChatHub, LoadStop.Web.Core, Version=5.0.0.0, Culture=neutral, PublicKeyToken=null]].

=>TargetInvocationException: Exception has been thrown by the target of an invocation.

=>InvalidOperationException: 'AddAzureSignalR(...)' was called without a matching call to 'IApplicationBuilder.UseAzureSignalR(...)'.

    Hi @razkhan78

    Could you check if UseAzureSignalR is executed in your Startup.cs when yo udebug the source code ?

    Yes, AddAzureSignalR is executed and breaking in LoadStopCoreModule.PostInitialize.

    Hi @razkhan78

    In that case, I couldn't understand the reason only with this exception. Is it possible for you to share your project via email with info@aspnetzero.com so we can check it for you ?

    As an alternative, you can try to upgrade your solution to .NET 3.x but I think it will be harder.
