>>In many cases, the designer is experienced with the controls and tools used and also knowledgeable of current design standards. He/she will likely design the appearance and behavior of base controls so they all look according to the overall desired design. He/she may not even do any actual development but work with skins or setting appearance behavior and standards for developer to follow. However, the developer will actually use the controls in the app. Other shops work differently.

If someone could go in and change the XAML and that resulted in the app's look changing, and this didn't require a recompile, then I'd say cool.

Depends on what the designer does in the xaml. Of course it will most likely require a recompile (based on my experience so far), but it doesn't necessarily have any effect on the code behind.

FWIW, I agree in some part with you. I do not think it is insanely difficult, but so far, I do not like it. I don't like the separation of xaml and code behind because it is easy to blur it and to create problems with some working in xaml and some in the code behind and some in both.

Everytime (so far) that I look at a real world WPF app's code, I find each developer is doing it differently.

However, I REALLY like alot of the neat stuff you can do with WPF gui wize... I see WPF as a first attempt at a really neat tool.
