Add generic counterparts for TryResolveNamed, TryResolveKeyed and TryResolveService #1263
Description
Problem Statement
The static class ResolutionExtensions provides a set of extension methods to manually resolve instances from a container. Some of these methods (e.g. Resolve and TryResolve) have a generic counterpart (Resolve<T> and TryResolve<T>), but others, namely TryResolveNamed, TryResolveKeyed and TryResolveService, dont.
Desired Solution
The generic counterparts could just call the non-generic extension methods and then cast the out parameter in the same way as the generic version TryResolve.
Alternatives You've Considered
Right know, one can either write their own extension methods or use other workarounds (e.g. resolve IIndex<string, T> and use TryGetValue as an alternative to TryResolveNamed).
