NetMQ
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.
Important note on backward compatibility
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.
Installation
You can find NetMQ in nuget.
Using
Before using NetMQ, make sure to read the ZeroMQ Guide. You can also read more about NetMQ at Somdorons blog.
Sacha Barber wrote a series of posts about NetMQ in his blog, take a look:
Socket Options/Identity and SendMore
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();
}
}
}
Contributing
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.
Regarding coding standards, we are using C# coding styles, to be a little more specific: we are using camelCase for variables and members (with m_ prefix for members) and PascalCase for methods, classes and constants. Make sure you are using Keep Spaces and 2 for tab and indent size.
You can also help us by:
