Hey guys,

While I was trying to implement our own UIExtensionSites, etc., I was wanting to simulate the CABs implementation, just with our stuff. However, whenever I override AddServices() as in the documentation:

...In ShellApplication : FormShellApplication<ShellWorkItem, ShellForm>

protected override void AddServices()
// The RIAUIElementAdapterFactoryCatalog will contain factories which
// create RIA-extended RIAUIElementAdapters which give us more control
// over building and managing menus and toolbars.
RootWorkItem.Services.AddNew<RIAUIElementAdapterFactoryCatalog, IRIAUIElementAdapterFactoryCatalog>();
I receive an exception during the Building of the RootWorkItem on application startup. Here is the exception information:

Service Microsoft.Practices.CompositeUI.WinForms.IControlActivationService is not available in the current context.

at Microsoft.Practices.CompositeUI.Collections.ServiceCollection.Get(Type serviceType, Boolean ensureExists) in C:\Program Files\Microsoft Composite UI App Block\CSharp\Source\CompositeUI\Collections\ServiceCollection.cs:line 300
Does anyone know If I missed something? I have not been able to track this down yet. I'ld be glad to help anyone with Ifragistics based Workspaces and thier NUnit tests....

Never Mind. The base.AddServices() method needed to be called. This is where IControlActivationService was added to the Services collection of the workitem.
