C# .NET communicate between computers over network [closed]

Question

How should I go about making an application with C# and .NET where, say, on one computer a button is pressed that triggers an event on the other?

I saw this:

Recommended way to communicate between processes running on different computers on the same network

I've never heard of WCF, is that what I should try?

Answer 1

You're question is way to broad however I can give you a brief overview of how WCF (and most client/server apps) work.

You create a WCF service and then you reference the WCF service (in VS right click references then add service reference) inside your client application. The click in the client application will send a message to the WCF service that will deal with that message.

As mentioned the getting started guides are pretty decent. The WCF Test Client is a great debugging tool as well. If you open the Visual Studio command prompt and type wcftestclient, it will pop up.

Answer 2

Yes, I would use WCF, because I know it's pretty easy to get a simple project running with WCF, and that will give you confidence to build on it. (Having said that, I dont have much experience with any other networking technologies.)

Start with this Getting Started tutorial.

Then if you have more specific questions, ask them.
