ASP.NET CORE 2.2 SignalR CORS Problem RRS feed

  • Question

  • Hello Everyone,

    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."

    When i am using this cors configuraiton, problem is solved

     services.AddCors(options =>
                        builder => builder
                        .SetIsOriginAllowed((host) => true) //for signalr cors

    Thanks for your sharing.

    Since your question is more related to ASP.NET forum, I will move it to OFF-TOPIC forum.
