How to drag form element in c# wpf constructor?

Question

WPF

I’ve been sitting bombing for 20 minutes because I can’t simply drag the same button in the constructor where I want, in the usual windows forms c # I can hold the button on any component in the constructor and rotate it in all corners, here in wpf I want to drag , AND AS A RESULT, THE SELECTION WORKS FOR ME, WHY DO I NEED IT, sorry for my screams, but I bombard so much that everything works differently here, but I don’t know this

Answer 1

firstly, it works fine, you just probably do not click on the element correctly;
secondly, a normal wpf developer does not use the constructor, but uses xaml
