wsweb's Issues

I feel like that there is something wrong with the memory leak problem?

Hi, I wrote a small test .net core console program. I generate about 5k client websocket and connect to the web server , about 2 minutes later, I call CloseAsync method from client websocket and this web server deals with the WebSocketMessageType.Close information and call WebSocket.Dispose() to clear the resources that websocket holds, however, I found that this dotnet.exe still holds about 300M memory space. I run this web server from donnet command window using command lines, and the operating system is Windows 10. I feel confused and do not know how to do. The code is down below

class Program
    {
        static void Main(string[] args)
        {
            List<ClientWebSocket> sockets = new List<ClientWebSocket>();
            Uri ServerUri = new Uri("ws://localhost:5000/ws");
            for (int i = 0; i < 5000; i++)
            {
                ClientWebSocket cs = new ClientWebSocket();
                sockets.Add(cs);
                cs.ConnectAsync(ServerUri, CancellationToken.None);
            }
            
            Console.WriteLine("All Connected");

            Thread.Sleep(2 * 60 * 1000);

            Console.WriteLine("Begin to disconnect");
            for (int i = 0; i < 5000; i++)
            {
                sockets[i].CloseAsync(WebSocketCloseStatus.NormalClosure, "closed by client", CancellationToken.None);
            }

            Console.ReadLine();
        }
    }

Calling Web API Controller from WS?

So in the example we have an echoloop, but how can we more realistically implement & pass a method & payload with the websocket which in turn calls a Web API controller let's say, and then returns that outgoing response from it.

Looking into it now, post when I get more info and/or get it working!
