The foundation of the WPF application development experience is formed from System.Windows, .NET Framework and code-behind and markup.
In addition to these, Windows Presentation Foundation is creating rich content user experiences by having comprehensive features. The content is put together as a package and delivered as “applications”.
Services and types that are collectively known as the application model are used to support the development of both browser-hosted and standalone applications.
To name one of the best applications built within the Windows Presentation Foundation we can mention SciChart, which is an application that enables clients to develop fast WPF charts.
