What's an example of a possible application that can be made with .Net?
Something you can do with good old C, only it'll be slower and bloated in .NET (just like in Java, mind you).
What's a current example of an application using .Net?
Something that should have been written in C, Lisp, or maybe Assembly.
Oh, the .NET API is more or less ok though (compared to the Win32 hell anyways), as long as you're running the native one.
Remember: .NET: Non-portable Virtual Machines™ (so useful, I'm buying a new processor for it)
