是否有一个TCP套接字库/协议可以进行消息成帧，并且在JS＆C＃中受支持？

Question

I'm in the process of building an application that requires clients to exchange messages between each other (similar to chat) using a server.

I want to write the server in JavaScript using Node JS, the client applications are written in C#.NET.

I've researched for a while and discarded Socket.IO due to the lack of C# support and because I'm looking for something more low-level and flexible/customizable.

I'm written once an application very similar which used the built in NodeJS 'net' module as the server and the C# TCPClient client-side, it works, but it uses a stream and I have to prefix the message length before each message.

I'm looking for something more redundant that has message framing out-of-the-box and is supported by the languages I'm using.

I've found the 'ws' (WebSocket) npm module which seems like a promising candidate, especially since it might go along well with the C# Socket class (which is also the underlying socket used by the TCPistener and TCPClient classes) but for the life of me I can't figure out if I'll still have to expect a Socket Stream or just set an event handler for new message events.

I'm looking for something that's really simple to implement and will notify for each message I receive so I can handle it, no matter the size of the message or buffer (I plan to send average messages a megabyte in size...), I never want to handle the buffer, and of course it should be well supported in the above languages.

WebSockets already work with messages, you don't need to prefix the size, just hook to the message event and it will be received complete.

I personally use websocket-sharp because it's portable and works perfectly under mono/linux, but if your target is just Windows yo can use the integrated .net websockets: https://msdn.microsoft.com/es-es/library/system.net.websockets.websocket(v=vs.110).aspx
