let's say I have a silverlight solution with three projects in it. First two are silverlight projects (application and web page for testing), and the third one is the project I added to be separated from the first two. When I define style and put it into App.xaml everything works just fine. My goal is to add another App.xaml (Silverlight Application Class) to the new project I created so I can have it all in one (classes and styles) project separated from the main silverlight projects (first two). I did it but it doesn't work, style is not applied and NewApp.Current.Resources.Count is zero even though i put style in it. If i put it back and adjust all headers to work, everything is fine again. What is my mistake?
