Answer 1

Check out Fody, and the PropertyChanged add-in. It will modify the IL after compilation to add the code to raise the PropertyChanged event for your properties. It's similar to PostSharp, mentioned in Lasse's answer, but it's free and open-source.

Answer 2

You will need some kind of AOP system to do this.

Either something where you wrap or inherit from your class, and dynamically generate the necessary plumbing in the wrapper/descendant to handle this, or some system like Postsharp that rewrites your code after compilation.

There is nothing built into .NET to handle this.
