WPF databinding to interface and not actual object - casting possible?

Question

Say I have an interface like this:

public interface ISomeInterface
{
...
}

I also have a couple of classes implementing this interface;

Answer 1

The short answer is DataTemplate's do not support interfaces (think about multiple inheritance, explicit v. implicit, etc). The way we tend to get around this is to have a base class things extend to allow the DataTemplate specialization/generalization. This means a decent, but not necessarily optimal, solution would be:

public abstract class SomeClassBase
{

}

public class SomeClass : SomeClassBase
{

}
