http://schemas.microsoft.com/winfx/xaml/2005' is not a recognized namespace

When I try to run QuickStart_1 from the new SDK I can't because it says:

Error 1 'http://schemas.microsoft.com/winfx/xaml/2005' is not a recognized namespace. Line 3, position 24. D:\Storage\Downloads\mce\QuickStart1\CSHARP\MyApp.xaml 3 24 QuickStart_1
and

Error 2 Unrecognized tag 'Page' in namespace 'http://schemas.microsoft.com/winfx/avalon/2005'. Note that tag names are case sensitive. Line 1 Position 7. D:\Storage\Downloads\mce\QuickStart1\CSHARP\Page1.xaml 1 7 QuickStart_1

Why would it say that Do I need to do something, or is the schema not available on MS's site
