I'm trying to use the Rect structure from System.Windows in MonoDevelop, but I can't find System.Windows in the packages list when I try to add a reference to it. There are lots of things like System.Windows.Controls.... and System.Windows.Forms... but not System.Windows by itself. How do I get access to Rect in MonoDevelop?
The Rect structure is defined in WindowsBase.dll (if targetting .NET 4). You would need to add a reference to that assembly to get access to it.
