WPF de arayüzü XMAL kısmından kodluyoruz ve xmal.cs kısmından da CodeBehind tarafını C# ile kodluyoruz. Bu kodlamaları yaparken bir elemente ulaşmak için x:Name kodunu kullarak nesnelere isim veriyoruz.
Ardından butonlar için de Click=”OlayAdi” şeklinde isimlendirme yaparak Click eventları oluşturuyoruz.
