Rect, where is it?

Question

This drives me crazy, creating new console application project, then

// adding it as reference of course
using System.Windows;

// somewhere in method
var rect = new Rect(1, 2, 3, 4); // no Rect

The type or namespace name 'Rect' could not be found (are you missing a using directive or an assembly reference?)

What happens with Rect ?

Answer 1

您应该添加WindowsBase.dll作为对项目的引用。
