An "Object reference not set to an instance of an object" error occurs when I create a new Silverlight project just after install Beta 2, I read tim's blog, and make sure right now the date of  "C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\Microsoft.VisualStudio.ServicesProxy.dll" is June 5, 2008, and the size of Silverlight Tools install in Control Panel is 1.18MB. It looks like still have another dlls to do not be updated or Adodb.dll register error.

The page in http://support.microsoft.com/kb/810098 talk about how to register Adodb.dll(.Net 1.1), but my current .Net framework is 3.5.
