WPF应用程序在Windows 10中具有WndProc异常； 在Windows 8、8.1中看不到

Question

It is my hope that there are developers out there who have undertaken to start work in Windows 10. I have not immersed myself to the point where I am coding strictly in Windows 10. Hopefully there are those of you out there who have seen similar behavior as explained below.

This application is a proprietary design; I won't be able to give too many details of a finer nature. I can tell you that it deals with getting the location of UI Automation Elements within any window on a screen.

This WPF application works very well in Windows 8 and 8.1. It works well in Windows 10, too. But I am getting the exception below when I attempt to use the application in the "Metro Outlook Mail" app. In general, WndProc in this class is dealing with the detection of pen events and finger events.

Here is the exception detail:

WndProc Exception: 
The pipe is being closed. 
Failed to get raw data from the pointer device. 
at WndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled)

Please let me know if any of you have seen this when testing your pre-Windows 10 app on a Windows 10 system.

Thanks

It would seem that the version of Windows 10 I was testing was too green. In testing the next release, this error went away.
