Last week I experienced a very annoying unhandled exception in XAML designer of Visual Studio 2008 SP1. It happened after installing of preview and beta tools for Silverlight 3, which was a mistake, because I installed them onto Silverlight 2 tools. When I installed the tools Expression Blend was working properly, but when I wanted to edit the code and use IntelliSense, the only choice was to switch to Visual Studio. Unfortunatelly, the Visual Studio was unable to render any XAML and shown an exception only. [More]
