ZeroTier Sockets for C# .NET (Work In Progress)

This library is a re-implementation of the .NET socket class (System.Net.Sockets.Socket) built atop ZeroTier's SDK using P/INVOKE and is designed to be a direct drop-in replacement. The library consists of three main objects: ZeroTier.Node, ZeroTier.Event, and ZeroTier.Socket. No code change is required in your application beyond a small snippet of startup code, renaming Socket to ZeroTier.Socket (where applicable) and handling a smattering of events.

tl;dr:

using System.Net.Sockets;
using ZeroTier;

void myCallback(ZeroTier.Event e)
{
	Console.WriteLine("{0} ({1})", e.EventCode, e.EventName);
}
...

ZeroTier.Node node = new ZeroTier.Node("path", myCallback, 9991);     	

node.Start();	
node.Join(0xc287ac0b42a6fb4c);

...

ZeroTier.Socket sock = new ZeroTier.Socket(ipAddr.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

sock.Connect(remoteEndPoint);

...

node.Stop();

See example.cs for a complete client/server implementation.

Building and running the example

make debug|release
./example.exe

Development notes

The SWIG interface file zt.i is only present for historical reference purposes. SWIG generates a ton of unnecessary boilerplate code which is hard to completely prevent using hints. You can generate a new wrapper for yourself using swig -c++ -csharp -dllimport "./libzt.so" zt.i but I would not recommend doing so unless you know what you're in for.
