Hi We are trying to connect to azure signalR

=>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]].

@ismcagdas
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 [email protected] 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.
