UnityContainerExtensions.Resolve(this IUnityContainer container, Type t, string name, params ResolverOverride[] overrides) seems to be missing

I am upgrading from Unity v3.5.1404 to Unity v5.11.9 and I ran into the following problem:

string key = "NamedRegistration"
Container.Resolve(serviceType, key);

will not compile.

In v3.5.1404 there is the following method:

///

/// Get an instance of the requested type with the given name from the container.
///

/// of object to get from the container.
/// Name of the object to retrieve.
/// Any overrides for the resolve call.
/// The retrieved object.
public object Resolve(Type t, string name, params ResolverOverride[] resolverOverrides) => this.DoBuildUp(t, name, (IEnumerable) resolverOverrides);

In v5.11.9 I can only find a generic version, but I don't know the type before runtime, so that is not optimal to use for me.

The documentation at http://unitycontainer.org/tutorials/resolution/type.html states the following:

Resolve(Type t, string name) | Returns an instance of the type registered with the container as the type t and with the specified name. Names are case sensitive.

What am I missing here?

If it is simply because the method is missing in UnityContainerExtensions, it is super easy to add, since the generic methods just calls a non generic implementation anyways.

I played a bit more with it and discovered the following:

var container = new UnityContainer();
return container.Resolve(serviceType, key); // Does not compile

var iContainer = (IUnityContainer) new UnityContainer();
return iContainer.Resolve(serviceType, key); // Does compile

So as long as you use the IUnityContainer interface it works fine, but if you use the UnityContainer directly, you get into the problem of the missing extension method.

To continue with the upgrade I simply started using the IUnityContainer interface to resolve with everywhere and now it all works.
