Weird behavior in VS2010 Beta 2 while adding a reference

Question

Hi everybody!

I 'm experiencing a weird behavior in VS 2010 Beta 2:

a) i 'm not able to add reference in a Silverlight 4 project (the .NET tab is empty) and i think it 's the same issue like this here and

b) (i thought what the heck i try to find the assemblies myself, so:) i'm navigating to

C:\Program Files\Microsoft SDKs\Silverlight\v4.0\Libraries\Client\System.ComponentModel.Composition.dll

selecting this particular dll and after selection VS2010 states in the path property:

C:\Program Files\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\System.ComponentModel.Composition.dll

What is wrong with VS2010 Beta 2? Did i do something to the GAC? Can i fix this? Or is this the way it works? (or is it only stubborn and simply doesn't like me :)) )

Thanks in advance
