twitchat is the basics of a Twitch bot in .NET Csharp
Why, you ask? Well, so it can run natively on Windows and be tampered with and customized by users. Twitch chat is NOT IRC - the interface that TMI provides is "irc-like" and does not strictly conform to the RFCs. This is fine and a lot of clients will work around it but none of the existing .NET C# IRC libraries will.
I wrote this in an afternoon in raw TCP sockets because I needed to, and it's my first time using it or Visual Studio so although the code is not as pretty or elegant as it should be, it does what I couldn't find a library to do - give me the basic tools to implement my own functionality.
I hope you find it useful, and while I don't suggest you create anything downstream from this as it will probably change in dependency-breaking ways, please credit me if you do use it.
