Stream interface implemented on top of System.Net.WebSockets.
dotnet add package WebSocketStream
Client example.
using WSStream;
WebSocketStream socket = WebSocketStream.Connect("ws://localhost:8080");
await socket.WriteAsync(new byte[] { 100, 101 }, 0, 2);
byte[] buffer = new buffer[1024];
int read = await socket.ReadAsync(buffer, 0, buffer.Length);
await socket.CloseAsync();The server uses a HttpListener under the hood for listening to incoming requests.
using WSStream;
WebSocketListener server = new WebSocketListener(8080);
WebSocketStream socket = await server.AcceptWebSocketAsync();
byte[] buffer = new byte[1024];
int read = await socket.ReadAsync(buffer, 0, buffer.Length);
await socket.WriteAsync(buffer, 0, read);
await socket.CloseAsync();Since System.Net.WebSockets does not provide synchronous methods for reading and writing to a WebSocket, the stream implementation uses the asynchronous equivalents in Read(buffer, offset, count) and Write(buffer, offset, count) and blocks the thread by calling GetAwaiter().GetResult().
