WebsocketsSimple provides an easy-to-use and customizable Websocket Server and Websocket Client. The server is created using a TcpListener and upgrades a successful connection to a WebSocket. The server and client can be used for non-SSL or SSL connections and authentication (including client and server SSL certification validation) is provided for identifying the clients connected to your server. Both client and server are created in .NET Standard and use async await functionality.
