What methods exist for local remote procedure call?

Question

I am working on two separate C# applications, and I'm trying to determine what is the best way to create a remote procedure call from one app to the other. Webservices are not necessary in this case because the applications will always run on the same machine (Windows OS). What types of RPC are available in C# and .net that I can use?

Answer 1

Try Protobuffers over Win32 RPC

Answer 2

I would recommend .NET Remoting configured with IPC channels, in my opinion this is the fastest way of communication between applications running on the same PC.
