I'm having real difficulties with XAML files in Silverlight since they get very big very fast when using Blend. It just becomes a wall of text after only a handful of controls are added and animated.
I'm hoping a better vesion of Blend will come out soon, so that our designers will never even have to see XAML. For now, though, that is not a solution - XAML still needs to be managed manually and it is a depressing task.
Has anyone found a solution to this? How do you keep your XAML files in order? How do you understand them when they get big?
Edit: I am especially interested in Silverlight solutions, since the most obvious WPF solution - splitting things up into resource dictionaries - is not supported in Silverlight.
