Performance Improvement for AssemblyLoading

[enisn]

Currently, assemblies are loaded and cached. It's good for calling twice or more. Because it'll return the same assembly collection after the first call. But that collection has never been released or cleared.

The main required action is, clearing that collection after ServiceCollection is built.

	.GetEntryAssembly()
	.GetReferencedAssemblies()
	.Select(s => Assembly.Load(s.ToString()))
	.Concat(new[] { Assembly.GetEntryAssembly() });
	if (AppDomain.CurrentDomain.FriendlyName == "testhost") // Test host is not referenced directly .dll
	{
	_assemblies = _assemblies
	.Concat(AppDomain.CurrentDomain.GetAssemblies());
	}
	assemblies = _assemblies.Distinct().ToList();
