RoutedViewHost - System.ArgumentException (PART_Container not found)

[ChrisWay]

Just trying to play with the new routing functionality, I've added a RoutedViewHost to my Window but it is throwing the above exception in the designer and when running the app.

I've created a test app to demonstrate. I expect I've missed something simple!

Here is the full stack trace:

You've hit a bug in RxUI 3.1 actually, I'm making RxUI 3.1.1 today which should resolve it

Nice one!

Hi Paul

I still seem to be having the same issue after updating to 3.1.1. It's still throwing the exception in the designer but it seems to be getting caught somewhere in your code at run time.

Seems all OK in 3.1.2. Thanks!
