NetMQ is 100% native C# port of ZeroMQ.
NetMQ is lightweight messaging library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. NetMQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.
NetMQ is still under development, although the current repository is pretty stable.
Since version 3.3.07 NetMQ changed the number serialization from Little Endian to Big Endian to be compatible with ZeroMQ. Any NetMQ version prior to 3.3.0.7 is not compatible with the new version. To support older versions you can set Endian option on a NetMQ socket to Little Endian, however doing so will make it incompatible with ZeroMQ.
We recommend to update to the latest version and use Big Endian which is now the default behavior.
You can find NetMQ in nuget.
Before using NetMQ, make sure to read the ZeroMQ Guide. You can also read more about NetMQ at Somdorons blog.
NetMQ documentation is still work in progress, but you can find a small example here.
using (NetMQContext ctx = NetMQContext.Create())
{
using (var server = ctx.CreateResponseSocket())
{
server.Bind("tcp://127.0.0.1:5556");
using (var client = ctx.CreateRequestSocket())
{
client.Connect("tcp://127.0.0.1:5556");
client.Send("Hello");
string m1 = server.ReceiveString();
Console.WriteLine("From Client: {0}", m1);
server.Send("Hi Back");
string m2 = client.ReceiveString();
Console.WriteLine("From Server: {0}", m2);
Console.ReadLine();
}
}
}
We need help, so if you have good knowledge of C# and ZeroMQ just grab one of the issues and add a pull request. We are using C4 process, so make sure you read this before.
Some of the areas we need help with:
- Testing with libzmq (original zeromq library) in version 2.2 and 3.2.
- Porting tests from ZeroMQ to c#.
- Documenting the High Level API using C# style comments
- Testing IPv6
- Compiling on Mono and run on linux
- Creating another High Level API which is the same as CLRZMQ
You can also help us by:
- Joining our mailing list and be an active member
- Writing tutorials in the github wiki
- Writing about the project in your blog
