Custom Theme: Expression Blend "Invalid XAML"

[Matthias]

Hi,

i created a Silverlight 4 Application (mainly with a RadGridView) and a custom theme (following this approach: http://www.telerik.com/help/silverlight/common-styling-apperance-themes-custom-theme-project-telerik-approach.html).

Works fine on my machine in Visual Studio 2010 and Expression Blend 4.
When our designer opens the (copied) project on her machine in Expression Blend 4 she always gets invalid XAML errors in various files (e.g. Telerik.Windows.Controls.GridView.xaml).

She even installed Visual Studio on her machine and there it no errors are thrown.
But it is quite useless, because she is a designer and doesn't want to create a custom theme solely through XAML code in VS!

Why does it work on my machine in Expression Blend and not on hers?

Dll version: 2012.2.0725.1040

Has it never been solved?

Thanks

might have found a solution for my case.

As i metioned, i just copied the project to the designers machine.
I have now updated all references to local dlls and emptied the bin and obj folders.
After recompiling the project now everything works in Expression Blend.
