title: Visual Studio 2008 support for new .NET 4
body: <p>Will Visual Studio 2008 be supported by new .NET 4 from the get go?</p>
  
  <p>I'm particularly interested in the System.Collections.Concurrent namespace and the parallel task library, which I would use immediately. </p>
  
  <p>Is it worth upgrading to Visual Studio 2010 when it comes out?</p>
