How can I use interface as a C# generic type constraint?

https://stackoverflow.com/questions/1096568/how-can-i-use-interface-as-a-c-sharp-generic-type-constraint

Is there a way to get the following function declaration?

public bool Foo<T>() where T : interface;

ie. where T is an interface type (similar to where T : class, and struct).

Currently I've settled for:

public bool Foo<T>() where T : IBase;

GetInterface from type
