Installation Issues

Before you start with thinktecture UIAnnotations make sure you have installed Expression Blend or the Expression Blend SDK.

• Expression Blend SDK for .NET http://www.microsoft.com/downloads/en/details.aspx?FamilyID=75E13D71-7C53-4382-9592-6C07C6A00207
• Expression Blend SDK for Silverlight http://www.microsoft.com/downloads/en/details.aspx?FamilyID=d197f51a-de07-4edf-9cba-1f1b4a22110d&displaylang=en

This is because thinktecture UIAnnotations uses System.Windows.Interactivity for the Expression Blend Behavior stuff.
