I am using Q2 2010 Silverlight controls with Silverlight 4.

I changed my xmlns declarations from the following old style:


and replaced those three declarations with a single simpler Silverlight 4 style:

This allows you to change the declaration for the transition from this:


to this:


Unfortunately, at least for the FadeTransition (does not happen for all the transitions) this results in the following error:

Error 69 Ambiguous type reference. A type named 'FadeTransition' occurs in at least two namespaces, 'Telerik.Windows.Controls' and 'Telerik.Windows.Controls.TransitionEffects'. Consider adjusting the assembly XmlnsDefinition attributes. 

Please research this problem.

Hello Greg,

We have several 'transitions' one for obsolete Navigation framework, one for the RadComboBox, RadMenu, RadDropDown etc. controls that have popups and that popup's show/hide is animated and one for RadTransitionControl. Some of them have the same names eventually (like the FadeTransition) We will rename or remove ambiguous references but it will be breaking change. For now we would recommend you to define an effects xmlns with the transitions for RadTransitionControl and not replacing them with the telerik xmlns.

Sincerely yours,
the Telerik team
