New Post: Issue in DelayedRegionCreationBehavior/PrismCode when region name for target element is null

Hi,

I manage to reproduce the exception by setting a region name to "" (empty), using the following code snippet in my view:

<ContentControl cal:RegionManager.RegionName="" />

Therefore, I would recommend you to check that all the regions in your views are correctly named and that you don't have any empty region name. If that is not the case, it would be useful if you could provide us with more information on how you are defining regions in your views.

I hope you find this useful,
