title: How to change VS2010 Add Reference box filter?
body: <p>I'm getting used to the new IDE (it's vc# express), but the first contact is somewhat confusing. When I open the Add Reference dialog and switch to the .NET tab, a label above the assembly list states: "Filtered to:.NET Framework 4". And it's true - I can reference .NET 4.0 assemblies only plus things like XNA 3.1. However I can't see older assemblies i.e. Managed DirectX libs, which are obviously installed on my computer as there was no trouble with adding a ref to them in vc#08. </p>
  
  <p>What is this? How to change the filter? The label is read-only. These sound like dull guy's questions, but I'm out of luck in finding an answer and there is no intuitive solution. </p>
  
  <p>Thanks in advance.</p>
