Siyamand Ayubi has developed a plug and play framework to animate page entrance and page exit in the WPF and Silverlight applications similar to the Powerpoint slides.
Windows Presentation Foundation (WPF) supports browser-style navigation that can be used in two types of applications: standalone applications and XAML browser applications (XBAPs). To package content for navigation, WPF provides the Page class [MSDN]. The WPF support of page navigation is very similar to the page navigation in the web. Each page has its own content and each page can contain hyperlinks to point to other pages similar to the web. But unlike the web, WPF has great build in support for animations.
