I assume the the last line should be rather something like:
var genrepo = Container.Resolve(actualType);

Ok, so I think what you're asking is - can Windsor close known open
generic type definition over a known type and give me back resulting
closed generic type, is that right?
However this does not make much sense as you'd have to reference it via
System.Object - which is not very useful.
Why is this repository generic in the first place? It seems to me you're
abusing generics here.
