I’ve wondering why the Visual Profiler in the WPF Performance Profiling Tool has never worked for me whilst others could run it fine. When I found the solution last night, I almost fell out of my chair. Here I was thinking the Zune location-restriction was absurd.
We heard that few folks complain that the Visual Profiler cannot correctly attach to the WPF application in the new WPFPerf for WPF 4.
After some research we think this has to do with a bug in our DateTime initialization which cause anyone in a time zone > GMT to not get any data in VisualProfiler (for a few hours at least).
Until we post a fix, a temporary workaround is to set your time zone < [Long: corrected] GMT (e.g.to Eastern or Pacific Standard Time Zones) when you first attach VisualProfiler.
