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.

Making more efficient resources

When we reference our resources, we can either use a StaticResource or a DynamicResource. If you remember from Chapter 5, Using The Right Controls for The Job, a StaticResource will look up the value of the resource just once, which is comparative to a compile-time lookup. A DynamicResource will repeatedly look up the value of the resource each time it is requested, whether it has changed or not, like a runtime lookup.

For this reason, we should only ever use a DynamicResource if we really need to and can attain much better performance by using the StaticResource class instead. If we find that we need to use a lot of DynamicResource references to access our resources, then we can refactor our code to data bind to properties in our StateManager class instead of the resources, to increase performance.

Another simple way to improve the performance of our resources is to reuse them. Instead of declaring them inline in the place that they are used in the XAML, we...
