Unity Container - Resolves Single Element

[dansiegel]

Description

Similar to issue #124 Unity has issues with multiple registrations followed by a ResolveAll.

Expected

container.RegisterType<IFoo, FooA>();
container.RegisterType<IFoo, FooB>();

// Return an instance of FooB
var fooB = container.Resolve<IFoo>();

// Return an IEnumerable with 2 elements FooA and FooB
var all = container.Resolve<IEnumerable<IFoo>>();
var allAlt = container.ResolveAll<IFoo>();

Actual

// This works as expected
var fooB = container.Resolve<IFoo>();

// This only returns a collection with the single element for FooB
var all = container.Resolve<IEnumerable<IFoo>>();

// This returns an empty collection
var allAlt = container.ResolveAll<IFoo>();
