I've discovered SplashScreenSource but I'm not sure how to hook that up to just show a single colour background instead of the loading screen. Any suggestions? 回答1: Add new XAML file to ASP.NET website, in which Silverlight will be

问题 I'm creating a silverlight for line of business application, and I'm using Forms Authentication. For user management, I'm deciding between using the built-in "ASP.NET Web Site Administration Tool", or create my own custom thing in Silverlight (making this part of the application experience).

问题 I'm writing a Silverlight 4 application and would like to check when opening the installed out of browser application, whether there is a valid internet connection (to then download some data from my website).
