I have a problem connecting with teamviewer to the device my WPF application is running on. If this connection is completed, the WPF application crashes with the following exception:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ComponentModel.Win32Exception: Cannot create a file when that file already exists

This problem seems to be the same as described
here .
The comments on this point mention the use of the clipboard as a possible cause of this problem. But my WPF application does not use the clipboard.
I hope someone can help me find the reason for this exception.
