ASP.NET-CORE 2.2 SignalR CORS

Question

I have a problem with ASP.Net Core 2.2 and SignalR. I am using SignalR between asp.net core and Angular. When i am using Asp.net core 2.0, everything work fine. But when i am using asp.net core 2.2 with same code, same classes am getting a cors error.

Warning: The CORS protocol does not allow specifying a wildcard (any) origin and credentials at the same time. Configure the policy by listing individual origins if credentials needs to be supported.

How can i solve this problem?

thanks
