I've enabled .NET framework source debugging in VS2010 (Premium, if it matters), and I can step through the methods inside .NET framework DLLs, but most values I can't read or poke around in and all I get is a red exclamation mark and a text that says:
Cannot obtain value of local or argument 'skipJournaledProperties' as it is not available at this instruction pointer, possibly because it has been optimized away.
Example:
Is there any way to enable reading of these values?
