We've just updated some of our developer machines to the new Silverlight runtime and developer runtime (4.0.60129.0) and VS 2010 is dying consistently on projects that use Bing layers. Has anyone else seen this? We can remove the Bing layers and use ArcGIS server layers with no issues.
It's not causing the runtime to crash when running the projects in the browser, only in Visual Studio after either debugging or switching to design and then back to XAML.
