title: How to target .net framework 4.0 from a SilverLight 4 Application Project?
body: <p>Issue:
  When creating a new SilverLight Application Project from Visual Studio 2010, the SilverLight application project's reference pointing to .Net Framework 2.0 assemblies. But I need to use some features only available since .Net Framework 4.0.</p>
  
  <p>Had done a few Google searches but reached no conclusion.</p>
  
  <p>Is there a way to update the targeted .Net Framework version for SilverLight application project in Vs2010?</p>
