How do you create an interface? What are the 4 defining principles of OO programming? Define what an abstract class is. What libraries does .NET use?

The interface question was extremely vague. Throughout all of my Computer Science courses, I've been taught to create program interfaces from the code, itself. So, I described how to do it in the main() function. However, looking back on it, I think they were looking for a specific answer relating to creating an interface using the .NET menu.
