I have a project that defines a Blend behavior. The Blend SDK used to create this behavior is Version 4. In Visual Studio 2010 I can work with this with no trouble at all. In VS 2012, the WPF Designer seems to have issues with the dll.
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
xmlns:b="clr-namespace:MyLib.Util.Behaviors;assembly=MyLib"
xmlns:v="clr-namespace:MyLib;assembly=MyLib"
In the WPF designer's intellisense neither namespaces appear, so I have to blind-type them.
Despite the fact that the designer would not propose the namespaces of MyLib and Interactivity, I can instantiate a control defined in MyLib and have perfect intellisense for that:
<v:ViewPort></v:ViewPort>
Now I want to add a Behavior to the ViewPort, the one defined in MyLib.Util.Behaviors
<v:ViewPort>
<i:Interaction.Behaviors>
<b:ZoomAreaBehavior />
</i:Interaction.Behaviors>
</v:ViewPort>
But again, there's no intellisense for b:ZoomAreaBehavior. The error list says that ZoomAreaBehavior could not be found. The very same code works in 2010 and will compile and run as soon as I close the Visual Editor.
Does anyone have an idea what goes wrong here?
Blend support was added in Update 1, Blend for Visual Studio 2012, Update 2 has WPF support built in.
