Description
Master Windows 8.1/Windows Runtime Programming Through 80 Expert Projects
This is the most complete, hands-on, solutions-focused guide to programming modern Windows applications with the Windows Runtime.
Leading Windows development consultants Jeremy Likness and John Garland present easy-to-adapt C# and XAML example code for more than 80 projects. Their real-world application examples help you apply Windows 8.1's best improvements, including large tiles, the new search control, flyouts, command bars, native WinRT networking, and new deployment and sideloading options.
Drawing on their pioneering experience, they illuminate key areas of the Windows Runtime API, offering uniquely detailed coverage of encryption, cloud connectivity, devices, printers, and media integration. You'll find cutting-edge tips and tricks available in no other book.
This is an indispensable resource for all intermediate-to-advanced Windows developers, and for any architect building desktop, tablet, or mobile solutions with Microsoft technologies. Its focus on both C# and XAML will make it valuable to millions of Windows developers already familiar with Silverlight, WPF, and/or .NET.
Coverage includes
* Creating robust app interfaces with the newest XAML controls, including flyouts and command bars
* Saving data in a persistent "roaming zone" for syncing across Windows 8.1 devices
* Using Visual State Manager (VSM) to build apps that adapt to various device resolutions and orientations
* Integrating virtually any form of data into your apps
* Connecting with web services, RSS, Atom feeds, and social networks
* Securing apps via authentication, encrypting, signing, and single sign-on with Microsoft Account, Facebook, Google, and more
* Leveraging Windows 8.1 media enhancements that improve battery life and app performance
* Networking more effectively with Windows 8.1's revamped HTTP implementation and new location APIs
* Using Tiles and Toasts to keep apps alive and connected, even when they aren't running
* Enabling users to send content between devices via NFC tap and send
* Ensuring accessibility and globalizing your apps
* Efficiently debugging, optimizing, packaging, and deploying your apps
* Building sideloadable apps that don't have to be published in Windows Store
"This book doesn't just focus on singular concepts, it also provides end-to-end perspective on building an app in WinRT. It is one of those essential tools for Windows developers that will help you complete your software goals sooner than without it!"
-Tim Heuer, Principal Program Manager Lead, XAML Platform, Microsoft Corporation

"This is a great from-the-ground-up, very complete book on building Windows Store Apps. You'll find it on your desk a year from now all dog-eared and marked up from use."
-Dave Campbell, MVP, WindowsDevNews.com
"Programming with Windows Runtime by Example is a must-have book for any professional developer building apps for WinRT/Win8.1, especially in the LOB space for modern apps on Windows 8.1. For me it is the reference I provide my team building LOB applications for WinRT. Jeremy and John have done a great job putting together a great reference and educational book on professional development for the WinRT platform."
-David J. Kelley, CTO, Microsoft MVP
"Jeremy and John are both very much IT masters from the old guard of software development. With countless years of bending, shaping, and influencing the world of software development behind them both, they continue to do so as they push forward into new and emerging technologies.
"As with everything they do, this book also reflects their ongoing dedication and passion for their quest to bring the reader not only the information he or she requires, but far more beyond that, they build knowledge step-by-step, then deliver it to the reader with cutting-edge, ninja-like precision to deliver exactly what knowledge is needed, when it's needed, and where it's needed.
"If you want to learn the Windows Runtime, then I can think of no finer book, and no finer guides to the WinRT landscape. By the end of this book, you'll have the knowledge, the power, and a hefty dose of passion to go out into the new millennium and create some of the best WinRT apps available."
-Peter "Shawty" Shaw, LinkedIn .NET User Group manager
"This book is an invaluable resource for budding WinRT developers. It covers the basics to more advanced topics like MVVM. Readers will find the chapter entitled 'Connecting to the Cloud' especially useful in getting up to speed with Azure and creating cloud connected apps."
-Daniel Vaughan, President of Outcoder, Microsoft MVP, Author of Windows Phone 8 Unleashed
"There are books that provide reference for a development topic, and others that you will read from cover to end. Programming the Windows Runtime by Example by Jeremy Likness and John Garland should be your go-to guide for getting up to speed on WinRT. Jeremy and John wrote this book with the intention of being easy to follow and hard to forget, and they succeeded in both areas. I recommend this book for all developers, whether new to WinRT development, or those like me who just want to fill in the gaps on advanced topics."
-Chris Woodruff, DeepFriedBytes.com, Microsoft MVP
