This is a syntax question. I have a generic class which is inheriting from a generic base class and is applying a constraint to one of the type parameters. I also want the derived class to implement an interface. For the life of me, I cannot seem to figure out the correct syntax.
This is what I have:
DerivedFoo<T1,T2> : ParentFoo<T1, T2> where T2 : IBar { ... }
The first thing that came to mind was this:
DerivedFoo<T1,T2> : ParentFoo<T1, T2> where T2 : IBar, IFoo { ... }
But that is incorrect as that causes T2 to need to implement both IBar and IFoo, not DerivedFoo to implement IFoo.
I've tried a bit of Googling, use of colons, semicolons, etc, but I've turned up short. I'm sure the answer is head slappingly simple.
Thanks.
