WPF/XAML Application Crashes when Blend not installed - Event Logs Attached

Question

Below is the full XAML for the WPF application, no codebehind. On computers that have Expression Blend 4 installed, the following application works. However, on machines that do not have Blend, the application crashes. This is extremely simplistic, but it appears that the [i:Interaction.Behaviors] portion is what is causing the issue, which is a behavior from Blend that creates a smooth animation.

Answer 1

You should ship System.Windows.Interactivity.dll with your application. Go to properties of that DLL in the references of you project and set Copy Local property to True. After that this assembly will be copied to the output folder of the project.

Answer 2

You need to include System.Windows.Interactivity.dll which is located at (Blend 3 pathing) ...Program Files\Microsoft SDKs\Expression\Blend 3\Interactivity\Libraries\WPF

That file is redistributable as defined by (Blend 3 pathing) ...Program Files\Microsoft SDKs\Expression\Blend 3\Redist.en.txt
