I've been trying for 2 days now to get this working, but I have a theme that worked fine in SL3 but now moving to SL4 I've got major problems.
To simplify it I took the myCustomThemeVista project from here http://www.telerik.com/community/forums/silverlight/general-discussions/how-do-i-apply-a-theme.aspx checked it worked and then upgraded the project to SL4. Obviously there where some breaking changes "TargetName" etc.. I think I resolved them but I still can't get the theme to apply.
Can someone help please?
