Overview of this book

Windows Presentation Foundation (WPF) provides developers with a unified programming model for building rich Windows smart client user experiences that incorporate UI, media, and documents.WPF has become the leading technology for developing rich client applications on the Windows platform, packed with features and capabilities. However, WPF is big; in fact, it's huge, causing a steep learning curve for the beginner and even for those already using some WPF features.Windows Presentation Foundation 4.5 Cookbook provides clear recipes for common WPF tasks. It includes detailed explanations and code examples for customizing and enhancing the basic scenarios, while gaining a deep understanding of WPF mechanics and capabilities.WPF is different and requires a different mind-set and approach. This book provides recipes and insights not only in its design but also its practical implementation details.Starting from the foundations of WPF, such as dependency properties and XAML, the book touches on all major WPF aspects, such as controls and layout, resources, and digs deep into its unprecedented data binding capabilities.The book shows data and control templates in action, which allow full customizations of displayed data and controls in a declarative way. Supported by styles and resources makes data binding all the more powerful. The Model View View-Model pattern is presented as an effective way of maximizing decoupling of components, while providing an elegant way of expanding applications while maintaining a tight grip on complexity.The later parts discuss custom elements and controls ñ the ultimate customization mechanism, and looks at multithreading issues, and how .NET 4.5 task parallelism features can enhance application performance.

Introduction


The computer world is going through a revolution in terms of the way code is written. From (mostly) single CPU systems, current computers have multi-core processors, capable of performing concurrent operations. The shift is mostly due to hardware limitations that don't allow current technology to increase CPU clock frequency by much (if at all). The solution: create more cores.

But, more cores means the "free lunch is over" (as Herb Sutter put it nicely). If we continue writing single threaded code, no amount of cores can help us speed things up. A lot of effort is now going in to getting back "the free lunch". One such effort is the Task Parallel Library introduced in .NET 4.

The UI world remains mainly single threaded. What concerns a UI framework, such as WPF, is keeping the UI responsive, which means offloading any significant work or significant wait to some background thread in some way so that the UI thread can keep pumping messages, keeping the application responsive....
