Mastering Windows Presentation Foundation

By: Sheridan Yuen

Overview of this book

Windows Presentation Foundation is rich in possibilities when it comes to delivering an excellent user experience. This book will show you how to build professional-grade applications that look great and work smoothly. We start by providing you with a foundation of knowledge to improve your workflow – this includes teaching you how to build the base layer of the application, which will support all that comes after it. We’ll also cover the useful details of data binding. Next, we cover the user interface and show you how to get the most out of the built-in and custom WPF controls. The final section of the book demonstrates ways to polish your applications, from adding practical animations and data validation to improving application performance. The book ends with a tutorial on how to deploy your applications and outlines potential ways to apply your new-found knowledge so you can put it to use right away.

Chapter 1. A Smarter Way of Working with WPF

When Windows Presentation Foundation (WPF) was first released as part of the .NET Framework version 3.0 in 2006, it was billed as the future of desktop application Graphical User Interface (GUI) languages and supporters claimed that it would put an end to the previous GUI technology, Windows Forms. However, as time passed, it has fallen far short of this claim.

There are three main reasons that WPF has not taken off as widely as previously expected. The first reason has nothing to do with WPF and stems from the recent push to host everything in the cloud and having web interfaces rather than desktop applications. The second reason relates to the very steep learning curve and the very different way of working that is required to master WPF.

The last reason is that it is not a very efficient language and if a WPF application has lots of 'bells and whistles' in, then either the client computers will need to have additional RAM and/or graphics cards installed, or they could face a slow and stuttering user experience.

This explains why many companies that make use of WPF today are in the finance industry, where they can afford to upgrade all users' computers to be able to run their applications optimally. This book will aim to make WPF more accessible to the rest of us by providing practical tips and tricks to help build our real-world applications more easily and more efficiently.

One of the simplest changes with the biggest workflow improvements that we can make to improve the way we work with WPF is to follow the MVVM software architectural pattern. It describes how we can organize our classes to make our applications more maintainable, testable, and generally simpler to understand. In this chapter, we will take a closer look at this pattern and discover how it can help us to improve our applications.

After discovering what MVVM is and what its benefits are, we'll learn several new ways to communicate between the various components in this new environment. We'll then focus on the physical structure of the code base in a typical MVVM application and investigate a variety of alternative arrangements.
