Summary: To improve the perception of a more responsive startup experience many WPF applications added a Splash Screen to their startup. The Splash Screen, which does not use WPF code, shows as soon as possible and is displayed until the application main window is rendered. Up until 3.5 Sp1 we pointed developers to sample code available on this blog. In the .Net 3.5 SP1 release we added basic Splash Screen support and new APIs and we recommend that you take advantage of it. (See download locations below) We are distributing the Splash Screen Visual Studio 2008 Sp1 Item Template on WPF Futures sites on www.codeplex.com/wpf.
