Why is WPF bad?

For desktop development, in the right hands, you can’t beat WPF – it trumps WinForms hands down. The biggest problem, however, is that it is complex; very complex, and people often make the mistake of approaching this using the same techniques they used to build WinForms applications.

Is WPF a technology?

Windows Presentation Foundation is a UI framework that creates desktop client applications. The WPF development platform supports a broad set of application development features, including an application model, resources, controls, graphics, layout, data binding, documents, and security.
