.Net Options for in-memory queues similar to AWS SQS

To help increase performance/reduce latency in my application I am attempting to replace my SQS Queues with in memory ones and I am looking for options.

A basic idea of my queue setup is as follows:

1. Command Handlers - Listen for messages sent to CommandHandlers queue, publishes messages to Events Queue
2. Builders - Listen for messages sent to Events Queue

I use a service bus to hook the queues up and decide where to handle them.

I have attempted to try out NetMq but I am struggling with the patterns I should be using. From my point of view all I am trying to do is create a queue, send a message to it, and receive the message.

Are there any examples of how I can do this/anything I can check out?
