I am using a fairly virgin Windows 7 Pro PC with VS 2010, Silverlight 5 (with toolbox, as seen from http://www.silverlight.net/downloads
Expressions, etc.. I am first trying to work with your demo ExecutiveDashboard -- while it loads into Visual Studio 2010 SP1 (and runs, however, has problems with connecting to data. I am not concerned with this). The problem I have, is anytime I try to open/edit any XAML file, Visual Studio Crashes and restarts.
Additoinally, I cannot even create a new XAML without it crashing. I have deleted all of the binary files, everything in the BIN, done a full CLEAN and rebuild, however, cannot open an XAML file without crashing.
Additionally 2 -- If I create a blank/new Silverlight appllication, I can add a XAML and view with no problem -- however, some Telerik controls do not work. For example, if I try to add RadChart I get a dialog box that states:
Object Reference no set to an instance of an object". I am simply dragging it onto the blank XAML page and get that error.
