Problem when extracting Silverlight resources

[hwsoderlund]

I have been using JustDecompile to extract resource files from the RadControls for Silverlight DLLs. Specifically, I wanted to get the GridViewRowTemplate from the Telerik.Windows.Themes.Windows8.dll file. The result that I get in JustDecompile is what I have pasted under "Example 1" below. As you can see, the SelectiveScrollingGrid object is empty and has empty and invalid values for its ColumnDefinitions and RowDefinitions properties. It also has this x:_UnknownContent property which I suppose is something that JustDecompile has generated. This is obviously not the real template, the entire contents of the SelectiveScrollingGrid is missing. So, there has to be a problem with the way JustDecompile extracts the resources, right?

By the way, the "real" template, as found in the folder \Themes.Implicit\Windows8\Themes\Telerik.Windows.Controls.GridView.xaml under the unzipped RadControls folder is as I have pasted under "Example 2". As you can see, there is a whole lot more to it than what was extracted using JustDecompile.

The version of JustDecompile that I am using is Version 2012.3.1016.8.

Example 1:
