Set Visual Studio as the owner of Another WPF Application Window

Hi,

My solution has 2 projects, 1 standalone WPF Application, and 1 Visual Studio extension that add a menu item to Tools menu. When the menu item is clicked, it will launched the standalone WPF Application.

I am looking to use WindowInteropHelper in the WPF Application like this:

var helper = new WindowInteropHelper(myWindow);        
helper.Owner = ownerHandle;

The ownerHandle should be the handle of Visual Studio main window. How do I get this handle?
