Popular Types

I was working on a presentation and was curious about how many types are in the .NET Framework 2.0. I had remembered a fine article by Panos Kougiouris in MSDN magazine that had used Reflection to determine that the 1.1 Framework had over 9000 types. I decided to run it on 2.0 -- total number came out over 28,600. If this trend continues, could WinFx end up with > 85K classes?

Here's the top 20 types based on Panos' app.

For some reason, I'm surprised to see UInt32 and Int16 there.

Possibly for the same reason I was frightened that IntPtr was so high? Compatibility with Win32 APIs, I would suspect.
