Error: Operation is not supported on this platform

[cooltrain7]

I've been running socket-sharp for 3 weeks now just fine (.net Core 2.1). Its started to throw this

System.PlatformNotSupportedException: Operation is not supported on this platform. at System.Action 1.BeginInvoke(T obj, AsyncCallback callback, Object object) at WebSocketSharp.WebSocket.open() at WebSocketSharp.WebSocket.Connect() | System.Exception {System.PlatformNotSupportedException}

I'm simply calling
using (ws = new WebSocketSharp.WebSocket(Address)) { ws.Connect(); //Other stuff after }

and it throws after connect.

I just tried to make a port of an app to UWP and I got the same error

I'm getting the same error also. Running on .NET Core 3.1.

I have same problem. I'm using secure connection and in one of ten cases (or so) program throws System.PlatformNotSupportedException after connect to server. When connection is nonsecure, it works fine.

I use connectasync() to connect to server,it throws the same error, but it works fine when I use connect.
Running on .NET Core 3.1.

@bradliuvskysoft thanks for the workaround, it indeed works without async.
Good for my test env...

Am working on a proper fork currently. Should finish basic support in a week. @tomerpeled
