[IronPython] Missing Framework Libraries

First, some clarification about terminology:

Assemblies are DLLs. The "built-in" ones that come with .NET are typically
stored in a special location known as the "GAC" or "Global Assembly Cache".
As such, you don't need to specify where they are exactly, because that's a
standard place where IronPython or C# knows to look.

System.Windows is a namespace. Any given namespace may have members in
multiple assemblies. In part, that's because there isn't really a namespace
"object" in .NET; it's merely a naming convention for types that we've all
agreed to follow.

So the fundamental unit that you're probably concerned with is a type. Types
are indeed located in assemblies, and you need to reference the appropriate
assembly in order to use the types contained therein. Probably the easiest
way to find which assembly a particular type is located in is to search MSDN
-- both Google and Bing do a good at this. Let's say I want to find which
assembly contains the type FrameworkElement. I simply search for
"FrameworkElement site:microsoft.com" and the first hit will generally be
the one I want. Near the very top of that page, it tells me "Assembly:
PresentationFramework (in PresentationFramework.dll)". So if I want to use
FrameworkElement, that's the assembly I need to reference.

Is this the information you're looking for?
