Hi,

I'm working on a project with a designer who's using Expression blend. We're both working on XP machines where the OS is set to the XP (Luna) theme.

It's my understanding that WPF chooses the .NET dll (PresentationFramework.Luna.dll, PresentationFramework.Classic.dll, etc) by checking the currently used OS theme (but I could be wrong :-}). Most of the forms we are jointly working on are fine but yesterday one that had been modified in Expression Blend had hardcoded in an xmlns referencing the Luna dll. This is something we obviously don't want to happen because we don't want to override the endusers chosen theme. The designer says he doesn't know what he may have done to cause this to happen so consequently we don't know how to avoid the issue in future.

Anyone with experience of Expression Blend know the (or a) possible cause?
Thx,
Viv
