Proper reconnect after WebSocketException

I use ClientWebSocket to connect to a socket server. If I stop the server I got WebSocketException what is OK. Then I try to reconnect.

If I use

await wsClient.ConnectAsync(serviceUri, cts.Token);

I get "System.InvalidOperationException: 'The WebSocket has already been started.'"

If I try to close it before reconnecting by

await wsClient.CloseAsync(WebSocketCloseStatus.Empty, string.Empty, CancellationToken.None);

I get "System.Net.WebSockets.WebSocketException: 'The WebSocket is in an invalid state ('Aborted') for this operation. Valid states are: 'Open, CloseReceived, CloseSent'' "

So what is the proper way of reconnecting after the connection has been lost.

I've just run into the same problem. Apparently you cannot reuse an aborted ClientWebSocket. The docs of ClientWebSocket.Abort() say:

The ClientWebSocket cannot be reused once it is aborted.
