Extension interface patterns

Question

The new extensions in .Net 3.5 allow functionality to be split out from interfaces.

For instance in .Net 2.0

public interface IHaveChildren {
    str         


        

Answer 1

A little bit more.

If multiple interfaces have the same extension method signature, you would need to explicitly convert the caller to one interface type and then call the method. E.g.

((IFirst)this).AmbigousMethod()
