通过Teamviewer连接时WPF应用程序崩溃 [英] WPF application crashes when connected via Teamviewer

问题描述

与teamviewer连接到运行WPF应用程序的设备时，我遇到了问题.如果建立了此连接，我的WPF应用程序将崩溃，但出现以下异常:

I have a problem when connecting with teamviewer to the device on which my WPF appliction is running. If this connection is made, my 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

此问题似乎与所描述的相同 此处.

This problem seems to be the same as described here.

在有关此问题的评论中，提到使用剪贴板是此问题的可能原因.但是我的WPF应用程序不使用剪贴板.

In the comments on this question, usage of the clipboard is mentioned as a possible cause of this problem. But my WPF application does not use the clipboard.

我希望有人能帮助我找到导致此异常的原因.

I hope someone can help me finding the cause of this exception.

推荐答案

我自己解决了这个问题.这是由MainWindow的标题空白引起的.设置后，问题得以解决.

I just fixed this problem myself. It was caused by an empty title of the MainWindow. After setting it, the problem is fixed.
