OK, what am I doing wrong here?

I think I have followed all the instructions required to work with the WPFToolkit but keep getting the following error...
Could not load file or assembly 'WPFToolkit, Version=3.5.30731.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

I started working in Expression Blend - this error does not appear there.  I brought the project into another PC with VS2008 (using C#) and there I cannot load any of the xaml, cs, etc files. - ending up with the above error.

I have validated the steps of downloading the binaries, extracting, referencing in VS Project, setting up the namespace and referencing the namespace in the instantiating of the datagrid control.

What am I doing wrong - really need some help.  Please.

I assume you are working with VS 2008, have .Net 3.5 SP1 installed and are creating a WPF project for starters. What is the location of WPFToolkit.dll on your machine and how are you referencing it from your VS project?

Hi KNana,

I had the same problem. You have to install .Net 3.5 SP1.
