IPC in .Net can be achieved using:
WCF
using named pipes requires .Net 3.0 and above.
Code example
- The WCF class NetNamedPipeBinding can be used for interprocess communication on the same machine. The MSDN documentaion for this class includes a code sample covering this scenario http://msdn.microsoft.com/en-us/library/system.servicemodel.netnamedpipebinding.aspx
Remoting
The original IPC framework released with .Net 1.0. I believe remoting is no longer being actively developed, and you are encouraged to use WCF instead
Code example
Inter-process communication via Remoting – uses a tcp channel

Win32 RPC using csharptest-net RpcLibrary
I came across a project recently that has wrapped the Win32 RPC library and created a .net class library that can be used for local and remote RPC
Project home page: http://csharptest.net/projects/rpclibrary/
MSDN references:
- How rpc works: http://technet.microsoft.com/en-us/library/cc738291(v=ws.10).aspx
- RPC functions: http://msdn.microsoft.com/en-us/library/aa378623(v=VS.85).aspx
Also has a google protocol buffers rpc client that runs on top of the library: https://code.google.com/p/protobuf-csharp-rpc/
WM_COPYDATA
For completeness it’s also possible to use the WIN32 method with the WM_COPYDATA message. I’ve used this method before in .Net 1.1 to create a single instance application opening multiple files from windows explorer.
