Most of the developers don't like the XAML design view in VS 2008 as it takes long time to load the desin view and some times it will crash the visual studio also.
The design view can be disabled in visual studio 2008.
1. Go to Tools-Options in menu.
2. Select Text Editor -> XAML -> Miscellaneous node in the popup.
3. Check the 'Always open documents in full XAML view' checkbox.
Even if this is not improving load time , try this option.
Hope It helps.
