Blend 4 throws exception when adding effect. RRS feed

  • Question

  • Blend version 4.0.20525.0

    Steps to reproduce:

    1. Create a new silverlight 4 project
    2. Add a border to the LayoutRoot
    3. With the border selected click New next to Effect under Appearance on the properties

    Result: throws exception "Could not load the assembly System.Windows because of the following errors occurred: Could not load type 'System.Dynamic.IDynamicMetaObjectProvider' from assembly 'System.Core, Version 2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e'... (several more types it could not load)

    Is my Blend busted and I need to reinstall or what?
