This book provides you with fast-track coverage of all the most important elements of the Silverlight 4 technology ranging from XAML to standard controls, from dealing with media to networking, from testing to deployment. It also reveals features introduced with Silverlight 4 and offers guidance on how to best utilize them. The book concludes with a pair of fully worked sample applications for you to follow through, because nothing reinforces your understanding of how concepts fit together as much as looking at finished code.

Microsoft’s commitment to the next-generation rich Internet technology platform and the relentless efforts of the Microsoft Silverlight team are clearly demonstrated in the recently released Silverlight 4 version. Silverlight 4 extends the core capabilities—data and media integration capa- bilities—and introduces some of the basic features of any line-of-business (LoB) application, such as printing, documents integration, reporting, rich offline capa- bilities (with the introduction of trusted out-of-browser applications), and local devices (e.g., web camera and microphone) integration. Tighter integration of Silverlight 4 with Visual Studio 2010 and .NET 4.0 and better integration of WCF RIA Services and data binding capabilities will certainly help the designer and develop- er communities to develop enterprise-level LoB applications supporting the agile development model. A long-awaited feature—Silverlight for mobile—is finally revealed in Silverlight 4. Silverlight 4 and Windows Mobile development tools enable development of inter- active Silverlight applications for the Windows 7 Mobile Phone series. Silverlight 4 for mobile, and official support of the Google Chrome browser, make Silverlight a truly cross-device and cross-platform technology platform. This is a great time to be a .NET developer, but even if you aren’t, you will find and learn that Silverlight has much to offer. This book is written for developers who have experience with .NET but may never have taken a look at Silverlight, or who already know Silverlight 3 and want to get familiar with Silverlight 4 features. The book contains everything you need to feel comfortable working with Silverlight, with several hands-on examples to show you Silverlight 4 in action. I encourage you to apply skills you’ve gained from this book to build Silverlight LoB applications and put them to work for your organization.
