Creating a modular application using Prism V2 - Screencast 2/4 : Visual Composition

The Discussion

• 

  I'm glad you're doing videos of these, but I'm disappointed by the quality of the video.  It's very difficult to read.

  Also, I get an exception when following along.  I'm doing so in a Silverlight Business Application project.  I created a ContentControl with the RegionManager.RegionName attached property value of 'TestRegion'.

  An exception occurred while creating a region with name 'TestRegion'. The exception was: System.Collections.Generic.KeyNotFoundException: controlType
     at Microsoft.Practices.Composite.Presentation.Regions.RegionAdapterMappings.GetMapping(Type controlType)
     at Microsoft.Practices.Composite.Presentation.Regions.Behaviors.DelayedRegionCreationBehavior.CreateRegion(DependencyObject targetElement, String regionName).

  Any ideas what might be happening?
