title: WPF/XAML Application Crashes when Blend not installed - Event Logs Attached
body: <p>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.</p>
