Blazer WASM / ReactiveUI

[mpinkus]

I'm working fine in a reactive viewmodel test, but in wasm I dont get the messages. websocket starts, no messages. Seems like a threading issue... any example would be appreciated for the wasm threading setup:

WebsocketClient = new WebsocketClient(this.AccessUriApp.AccessUri);

                WebsocketClient.ReconnectionHappened.Subscribe(info =>
                    this.Log().Debug($"PubSub Reconnection: {info.Type}"
                    )
                );

                WebsocketClient.MessageReceived
                    .Select(z => Observable.FromAsync(
                        async () => {
                        switch (z.MessageType)
                        {
                            case System.Net.WebSockets.WebSocketMessageType.Binary:
                                this.Log().Debug($"%%%%%%%%%%%%%%% PubSub [Binary] Message Received %%%%%%%%%%%%%%%%%");


                                break;
                            case System.Net.WebSockets.WebSocketMessageType.Close:
                                this.Log().Debug($"%%%%%%%%%%%%%%% PubSub [Close] Message Received %%%%%%%%%%%%%%%%%");
                                break;
                            case System.Net.WebSockets.WebSocketMessageType.Text:
                                this.Log().Debug($"%%%%%%%%%%%%%%% PubSub [Text] Message Received %%%%%%%%%%%%%%%%%");
                                        break;

                            default:
                                break;
                        }
                    }))
                    .Concat() // executes sequentially
                    .Subscribe();

                _ = WebsocketClient.Start();

ok the issue is this: Disconnection: Error Operation is not supported on this platform. at System.Net.WebSockets.ClientWebSocketOptions.set_KeepAliveInterval(TimeSpan value) ... any thoughts on use in wasm?

Hello @mpinkus,

only KeepAlive configuration is not supported in Blazor?
According to this, ClientWebsocketClient should work in wasm.

Btw here is a working example: crypto-watcher-blazor
