Caution :

It is important to understand that the Splash Screen has the following limitations:
·         It does not actually improve application cold startup time.
·         Cannot display sequence of splash images or animation.
·         Does not support for animated GIFs
·         Does not support earlier versions of VS (earlier than VS2008 Sp1). You should still be able to use the APIs (e.g. Approach C)

·         Does not support XBAPs (XBAPs already have their own improved coldstart progress page in  .Net 3.5 Sp1)
·         Does not have  XAML support for setting splash screen image
·         Expression Blend does not provide UI to  set the SplashScreen build action
