Add reference .Net Tab

I have installed Orcas and any new Silverlight project I try and create automatically shows errors on first build:

"The type or namespace name 'Name' does not exists in the namespace 'namespace' (are you missing an assembly reference?).

All of the namespace references were missing

using System;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Documents;

etc

Easily rectified, I thought, by going to Project > Add Reference and clicking the .Net tab, but the .Net tab dialog is devoid of any dll's. So I browse to where my system showed me that the System.Windows.dll is and I double click it.

It adds the reference, but I cannot find any other dll's.

Any ideas?
