T <xt1> fn(int a, int b) is interface possible for t

Rightthen

Dear Fellows,

interface Ico
{

T Result{get ; set; }
SomeType Call(Delegate a, params object[] b);
SomeType PreviousChainCell{get ;set ; }
}
works fine but i want that the returing type (SomeType) of the methods not to be explicitly described here, type implementing it should name itself instead of SomeType.

what i want is like this
T2 Call(Delegate a, params object[] b);
where T2 is the implementing type of the interface i don't know how to get it right
compiler won't let me specify like this
i tried
interface Ico
but that does not work either.

Is it even possible in c#

Thanks
Regards

Accepted answer
I'm afraid that it's not possible to do this in C# where generics are nailed down pretty tight.

Firstly, there's no way to constrain a type parameter so that it can only refer to a generic type which rules out stuff such as T2.

Secondly, you can't constrain a type parameter in an interface to only refer to its implementing type.

Also, the fact that the Call method is itself generic makes it difficult to come up with anything that's even close.
