Documentation says that Design Preview in Silverlight 3 Tools for Visual Studio 2008 is away. The preview with Silverlight 2 was only read only and sucks. OK is bad but no preview is even worse. When you right click a XAML file there is still context menu “view Designer”.
So why? Cause designer is still here- but hidden!
move mouse to bottom of XAML editor.
No mousecoursor is a double arrow which can be drag by mouse down to upper direction.
Now click relaod and ready.
After closing file- designer setting is away. Perhaps i find a solution somewhere in template settings.
