Hi Nigel,
Thanks for pointing that out. Yes, there was a mistake while updating the template file for the ObjectContainerProvider. We have fixed that.
You can make the same change (change ObjectContainerProvider to IObjectContainerProvider) to the template file found under <Installation folder>\sdk\IDEIntegrations\templates\templateObjectContainerProvider.cs/vb, so that the right code is generated whenever you execute the wizard.
Your telerik points have been updated.
Greetings,
Ady
the Telerik team
