Attribute /SLApplication;component/Style/XamOutlookBar.xaml value is out of range. [Line: 17 Position: 44]

The given key was not present in the dictionary.


So I played around with this error for a while.  I have not fired up a new Silverlight 3 project since Visual Studio 2010 RC came out.  In beta 2 things were different. 

In Visual Studio 2010 RC you have to provide the fully qualified class path in the Resource Disctionary’s source attribute.

In my code block above the MyApp.Admin.SLApplication is the FQCP for the Silverlight application class.
