Could not load type System.Windows.Controls.Primitives.Multiselector

May 5, 2009 at 4:32 PM
I have a wpf project that I created on an xp machine using the march release of the toolkit. The project worked fine. My machine was upgraded to vista 32 bit and then when I loaded my project I got the following:

Could not load type 'System.Windows.Controls.Primitives.MultiSelector' from assembly 'PresentationFramework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. on the line that contains the xaml for the datagrid:

I also get the following:

Error 5 The tag 'DataGrid' does not exist in XML namespace 'clr-namespace:Microsoft.Windows.Controls;assembly=WpfToolkit'. Line 10 Position 18. 

I have .net 3.5 sp1, vs2008 Version 9.0.30729.1 SP

I even downloaded a sample from this site and get the same errors when I load the sample.

please Help!
