WPF provides a comprehensive set of application-development features that include Extensible Application Markup Language (XAML), controls, data binding, layout, 2D and 3D graphics, animation, styles, templates, documents, media, text, and typography.
WPF binding offers four types of Binding. Remember, Binding runs on UI thread unless otherwise you specify it to run otherwise. OneWay: The target property will listen to the source property being changed and will update itself.
In the case of WPF, the Main() is automatically generated when App. xaml is built and the /m switch is specified to make the C# compiler use that class as entry point. If you look at the project properties however, you'll find there's a setting for you to choose the startup object.

I would say the single most important concept is the UI pattern Model-View-ViewModel, or as I like to call Model-View-ModelController. This is crucial to building apps successfully in WPF. Besides that, the real conerstones are Databinding, Templating, and Styles as others have mentioned. There is a nice post here on some common pitfalls to avoid when developing in wpf.
