Reflector has been invaluable over the years.  I’m torn about the idea it’s become a paid for tool, and by all means folks should be compensated for great work.  Not sure where Lutz is in the cash flow.

But, the ICSharpCode guys have released ILSpy at www.ILSpy.com  (http://wiki.sharpdevelop.net/ilspy.ashx)

Right now the limitation is it’s NetFx 4.0+.  So, keep that unfortunately self-updating version of Reflector around.  I still may pay, but it’s good to know there’s competition.
