PropertyChangedTrigger doesn't work - wrong namespace?!

Question

Hey guys,

I put the following (via Expression Blend 4) in my XAML file:

<i:Interaction.Triggers>
   <ei:DataStoreChangedTrigger Binding="{Binding StatusMessage}">
   <ei:ControlStoryboardAction/>
   </ei:DataStoreChangedTrigger>
</i:Interaction.Triggers>

When building the project, Expression Blend throws following error:

The tag 'DataStoreChangedTrigger' does not exist in XML namespace 'http://schemas.microsoft.com/expression/2010/interactions

What's the issue?

Thanks!

Sounds like you haven't added a reference to the Microsoft.Expression.Interactions.dll or if you have you haven't referenced the Blend SDK 4 version of the this dll.
