Using SharedResourceDictionary in Silverlight

Christian Moser provides a SharedResourceDictionary for WPF to reuse and initialize resources on开发者_StackOverflow中文版ly once.

I´ve tried to use his implementation in my Silverlight 4 application, but i´m getting COMExceptions in Visual Studio or a message that the element is already a child of an other element.

Has anyone successfully used SharedResourceDictionary in a Silverlight application or is there a similar way to reuse ResourceDictionaries?

It doesn't look promising for using it in Silverlight, I think this bug on Microsoft Connect relates exactly to the problem, and that was last updated 2 years ago...
