The piped stream are bidirectional communcation.Meanwhile they can read and write.

Write the NamedPipeServerStream and NamedPipeClientStream in two different hosts.

Today I created a console application to host the NamedPipeServerStream at first,then add another console application in the same solution to host the NamedPipeClientStream. Right click the solution and click properties and select the Multiple startup projects and then set all of their start action as Start as below.
