Answer 1

WCF

Windows Communication Foundation

In general you need to implement a client - server architecture and define interface endpoints to communicate between the process that acts as client and the server process.

The other way is to create a Remotable Class a dynamic library (DLL) so that the same remoted class can be referenced by both the client and the server.

The server will have to create instance of the remote class to be able to make sense of the object-oriented data you communicate, and can listen for example on a TCP channel.

e.g

ChannelServices.RegisterChannel( new TcpChannel( PORT_NUMBER) );       

RemotingServices.Marshal( your_remoted_class, "name_connection" );

Or for local use you can just use the IpcServerChannel API

Now on Client if you used TCP port to listen on for server

string remoted_url = "tcp://localhost:<your_port_number>/connection name";

remoted_object = (RemotedClass)RemotingServices.Connect

( typeof(RemotedClass), remoted_url );

The client can now call the public functions through remote_object.

Answer 2

If you are little bit specific about technology, then I could narrow down my answer.

In a very generic note, these are ways to communicate between two processes.

1. Message communication through a common file.
2. Socket communication between two processes.
3. Mutex
4. Any intermediate service.

There are several other ways.
