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

I have quite a few gripes with clrzmq and clrzmq2, and NZMQ is incomplete
in several areas, so over a few weekends this past month I've written a new
C# API for ZeroMQ based on the 2.0.10 release of zmq.h.
ZeroMQ Interop v0.8.190.10354 (beta)
http://zeromq.codeplex.com
* Feature-complete
* MIT licensed
* Targeted at both Microsoft and Mono .NET 2.0 CLRs (though it does require
a 3.5 compatible compiler, basically for lambda syntax)
* Includes binaries for both 32 and 64bit platforms (without any #ifdefs)
Here's an example using Pub/Sub sockets-
// Set up a publisher.
var publisher *=* new *ZmqPublishSocket* {
Identity *=* *Guid**.**NewGuid*()*.**ToByteArray*(),
RecoverySeconds *=* 10
};
publisher*.**Bind*( address: tcp://127.0.0.1:9292 );
// Set up a subscriber.
var subscriber *=* new *ZmqSubscribeSocket*();
subscriber*.**Connect*( address: tcp://127.0.0.1:9292 );
subscriber*.**Subscribe*( prefix: ); // subscribe to all messages
// Add a handler to the subscriber's OnReceive event
subscriber*.**OnReceive* *+=* () *=* {
*String* message;
subscriber*.**Receive*( out message, nonblocking: true );
*Console**.**WriteLine*( message );
};
// Publish a message to all subscribers.
publisher*.**Send*( Hello world! );
A few things that make this sample stand out from the other two ZeroMQ C#
libraries-
* 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).
I'd love some feedback. I'm just starting to use it in a project I'm
working on, and so far it all seems to be working smoothly and at high
throughput, but I'm releasing it as beta because I don't feel that it has
enough real-world experience yet.
