Inherit from an abstract class and realize an interface at the same time

I have C# class definition

MyViewModelClass: INotifyPropertyChanged, MyAbs开发者_开发百科tractBaseForVMClass

It won't compile. Gives and error at the start of MyAbstractBaseForVMClass literal:

Interface definition is expected.

Can I not realize an interface, and inherit from an abstract class at the same time?

No you can. Just reverse them.

MyViewModelClass: MyAbstractBaseForVMClass, INotifyPropertyChanged

Interfaces always come after classes.
