Visual Studio 2010 Performance Analysis and Silverlight 4 OOB Apps

Question

I'm using Visual Studio 2010 Beta 2 and creating an Out of Browser Silverlight 4 application. There are some slow bits and I'd like to profile it, but whenever I try, the application loads, the profiler starts but exits almost immediately. It reads:

Profiler started
Successfully attached to process: 2088
Exited from process: 2088
Collection file exited: c:\projects\SPASilverlight\sllauncher091213(3).vsp
Profiler exited
PRF0025: No data was collected. 
===================== Profiling Complete =====================

Is this not possible or am I missing something?

Answer 1

Did you try to run your app as out of browser with elevated permissions? I guess profiler might need more permissions so it can reflect/instrument.

Answer 2

You could try my steps to profile from command line:

At the very least you'll get a more verbose error message that will help you determine what the problem is.
