Stephen Toub - MSFT
One of the primary reasons we've released CTPs of Parallel Extensions is to solicit feedback on the design and functionality it provides.  Does it provide all of the APIs you need to get your job done?  Are there scenarios you wished the APIs supported and that you need to work around in klunky ways?  And so forth.  We've ...
