I’ve long thought that WPF Performance Tools for .NET 4.0 from the Windows 7 SDK was completely broken, the Visual Profiler never showed anything. Seems I just hadn’t done a good enough job when searching for a fix.

Now three years later I stumbled across a blog post at msdn.com about a TimeZone fix for WPF Performance Tools that fixed my issue.
