Hello,<br><br>in the WPF designer VS2010 CTP, the property editor of a control does not allow to make a choice between different classes for a property, when different possible classes are defined using the NewItemTypes attribute.<br><br>In VS2008, a combo box would appear and allow to make a choice. In Vs2010, no such choice is possible any more but the text &quot;Value must be set in XAML&quot; is displayed.<br><br>Will this feature be available again?<br><br>Thanks<br>Karlo© 2009 Microsoft Corporation.
