I want to develop a program which will communicate over the internet to another c# program.
What is the best method of doing this? Is it to use sockets, or to use something more TCP based? Any help or information would be great.
Something I also want to achieve is a secure connection, so the method must allow for encryption.
Is it to use sockets, or to use something more TCP based?
Something "TCP-based" does use sockets.
Take a look at System.Net.Sockets, you probably just want to use TcpClient and TcpListener, and maybe you'll get better advice regarding a secure connection, but that probably involves using something in System.Net.Security
The only real decision you have is wether its TCP or UDP
And that's an easy decision: you want TCP, unless you specifically don't.
Or you're expecting a *lot* of connections in which case you have no choice either but at a cost :P
