Visual C# .NET (C#) is relatively easy to learn for anyone familiar with another object-oriented language. Even someone familiar with Visual Basic 6.0, who is looking for an object-oriented language, will find C# easy to pick up. However, though C#, coupled with the .NET Framework, provides a quick path for creating simple applications, you still must know a wealth of information and understand how to use it correctly in order to produce sophisticated, robust, fault-tolerant C# applications. I teach you what you need to know and explain how best to use your knowledge so that you can quickly develop true C# expertise. Idioms and design patterns are invaluable for developing and applying expertise, and I show you how to use many of them to create applications that are efficient, robust, fault-tolerant, and exceptionsafe. Although many are familiar to C++ and Java programmers, some are unique to .NET and its Common Language Runtime (CLR). I show you how to apply these indispensable idioms and design techniques to seamlessly integrate your C# applications with the .NET runtime, focusing on the new capabilities of C# 3.0

The Windows Presentation Foundation (WPF) is a modern graphical display system for Windows. It’s a radical change from the technologies that came before it, with innovative features such as built-in hardware acceleration and resolution independence, both of which you’ll explore in this chapter. WPF is the best toolkit to use if you want to build a rich desktop application that runs on Windows Vista, Windows 7, and Windows 8 in desktop mode (as well as the corresponding versions of Windows Server). In fact, it’s the only general-purpose toolkit that targets these versions of Windows. By comparison, Microsoft’s new Metro toolkit—although exciting—is limited to Windows 8 systems only. (WPF applications can even be made to run on ancient Windows XP computers, which are still found in many businesses. The only limitation is that you must configure Visual Studio to target the slightly older .NET 4.0 Framework, rather than .NET 4.5.) In this book, you’ll take your first look at the architecture of WPF. You’ll learn how it deals with varying screen resolutions, and you’ll get a high-level survey of its core assemblies and classes. You’ll also consider how WPF has evolved from its initial release to version 4.5
