Answer 1

One option would be to use WCF named pipes (net.pipe) the other option would be Anonymous Pipes for Local Interprocess Communication

Excerpt:

Anonymous pipes offer less functionality than named pipes, but also require less overhead. You can use anonymous pipes to make interprocess communication on a local computer easier. You cannot use anonymous pipes for communication over a network.
