Windows 10: WPF: Drag & Drop virtual folder from WPF to File Explorer

Hi, I am developing ADB Explorer, a UI for ADB in WPF.I am trying to implement support for Drag & Drop to Push / Pull files between PC and an Android device, and while accepting files dragged into the app is quite easy since I can just use the provided path, its the other direction that I still can't get right. Namely, dragging a folder from the app to File Explorer.I started by using VirtualFileDataObject class to transfer the files as streams, which is what's usually recommended for files that do not yet exist on the PC, but since ADB works best when transferring files instead

Enable visual styles in WPF application

EUREKA!

Steps:
1) I made a Windows form (HostWPF namespace, Form1 is the form).
2) I added a reference => System.Windows.Forms.Integration which contains classes that enable interoperation between the Windows Forms and WPF technologies. When you use System.Windows.Forms.Integration classes, you can host Windows Forms controls on WPF pages, and WPF elements in Windows Forms-based applications.
3) Then added a control (damn Vi$ual $tudio 2010 does not allow to add a WPF window) but after adding I edited the XMAL code in the way I want *Wink
4) The next steps are simple. Download the first attachment. But => see the photo.
It crashes!!!!!
5) Finally???
We must use System.Windows.Forms.Application.Exit(); command because the WPF window behaves like a classical Windows Form.
Download the second attachment. Note that the Windows form's name is Initial.
Enjoy!

 

Enable visual styles in WPF application

I think WPF is incompatible with Visual Styles. Visual Styles is for WinForms. WPF is an entirely different animal.

 

Terminate WPF/Windows forms applications....

WPF has no concept of MDI applications. In fact Microsoft is trying to discourage any one using that form of application. I'm new to WPF and I really like MDI applications. It allows me to move quickly between windows and compare the content of different windows. Furthermore, sometime the content of one window is useful for another so I can copy and paste. I think it's a great user experience for working mode.
To continue, download the attachment!
It includes two folders, they are very simple code.
The point is how you can terminate an application (Windows Form and WPF).
