Changes
* If loading of a custom XAML template fails, the file as well as the type browser are directly accessible from the error template (analog to [[Developer Mode]])-->
* The [[Property_Wizard_(Client)|property wizard]] will no longer get interrupted by the Guid property editor (when a user decides to further navigate to the Guid editing page)
* Improved the default UI template for child items under data templates.
