How do I attach my application into another .Net application?

I'm trying to create a quick debugger, wherein I can attach my application to a running .net process and execute scripts from there. I'm using C#.

How will I do it?

Thanks :)

From stackoverflow

• This looks like a decent introductory article.

• You can attach to a process in Visual Studio and use VS tools for debugging. What does your application do that would require it to be attached to other processes outside of VS?

  Marc Vitalis : The application should be small, and there will be no codes to step into. I'll be pushing those scripts in the running process.
