當通過Teamviewer連接WPF應用程序時崩潰

當我的WPF應用程序正在運行的設備上連接teamviewer時遇到問題。如果連接成功，我的WPF應用程序崩潰，並顯示以下異常：當通過Teamviewer連接WPF應用程序時崩潰

這個問題似乎描述 here是相同的。

在對這個問題的評論中，提到剪貼板的用法可能是導致此問題的原因。但我的WPF應用程序不使用剪貼板。

我希望有人能幫我找到這個例外的原因。

從鏈接SO問題中的註釋和異常跟蹤中，我會說應用程序試圖訪問某些win32功能，而TeamViewer沒有任何功能。你可以嘗試捕捉異常，當它被拋出並找到一些更多的信息？您可能還想從堆棧跟蹤中移除您的公司名稱。 – Clint

我想一些更多的信息是必要的，例如。拋出異常的代碼片段 – Pikoh

1 - 您是否嘗試過使用簡單的測試應用程序？ 2-在你的情況下，當你創建遠程連接時，應用程序已經運行並崩潰？ – GCamel

我剛剛解決了這個問題。它是由MainWindow的空標題引起的。設置後，問題就解決了。
