What Is WPF

• WPF aka Windows Presentation Foundation
• The main purpose of WPF is to give to a programmer or designer a possibility to build rich GUI applications
• Actually WPF came to replace WinForms
• WPF is part of .Net Framework 3.0 or higher

Some basic stuff about WPF

• In order to begin write your WPF application you can open Visual Studio and chose project type named "WPF Application"
• GUI consists of two files - *.xaml and code-behind *.cs
• XAML file is actually an XML which describes the GUI
• One of the strongest side of WPF concept is logical separation of appearance and behavior

What you should know before starting to write your first WPF application?

• Forget about how you wrote your WinForms applications, in WPF it is all about the bindings
• Before you start to write your first WPF application you MUST to read about MVVM (Model-View-ViewModel pattern), believe me it`s super important
• If you listened to my advice then your code-behind file *.cs will be almost empty, all the GUI logic is configured in *.xaml file and all GUI elements should be bonded to relevant ViewModel
• And again NEVER write GUI logic in your code-behind file *.cs

Well that`s it for to today, gotta run, have a lot work to do.

If you have questions, please write me in comments section.
