> User [~samimajed] described in a comment for TINKERPOP-2019 a situation where
> the Gremlin.Net.Driver tries to close a {{ClientWebSocket}} which fails
> because it was apparently already closed:
> {code}
> System.Net.WebSockets.WebSocketException:
> at System.Net.WebSockets.WebSocketValidate.ThrowIfInvalidState

> {code}
> Gremlin.Net should check the state of the {{ClientWebSocket}} before trying
> to close it as the server could have already closed the connection.
> [The implementation for this in
> SignalR|https://github.com/SignalR/SignalR/blob/1fba14fa3437e24c204dfaf8a18db3fce8acad3c/src/Microsoft.AspNet.SignalR.Core/Owin/WebSockets/WebSocketHandler.cs#L92]
> could be a good starting point as it uses the same underlying WebSocket
> implementation.
