[zeromq-dev] I've written a completely new C# API for ZeroMQ

[Vinicius Chiele]

Great job Alex, your implementation is very clean and simple, I liked it.

> subscriber*.**Connect*( address: "tcp://127.0.0.1:9292" );

> * There's no need to manage your ZeroMQ context; it's taken care of on a
> per-AppDomain basis using refcounting.
> * There is no "message" object because it provides no added benefit in C#.
> Messages are simply Byte[]s, with overloads throughout the API that accept
> Strings.
> * First-class support for .NET events programming, implemented using
> zmq_poll() (but that's completely transparent to the user).

> enough real-world experience yet.
