我面對以下問題：在.NET 4.5中的Microsoft Visual Studio 2013上開發的應用程序需要在Window XP平臺中工作。我正在使用.NET 4.0重建軟件並進行一些修改以添加兼容性，但是當我點擊按鈕時，應用程序崩潰並且不顯示明確的錯誤消息，並且跟蹤資源不記錄任何內容。在應用程序啓動時，我有一個要求用戶輸入姓名的小窗口，此功能正常工作。任何人有什麼建議我可以做什麼？從.NET 4.5到.NET 4.0的Wpf應用程序
EDIT 1：
後續代碼是問題的根源，該代碼是使用.NET 4.0編譯：

如果我不不做任何實例或引用串行端口的應用程序不崩潰。存在一種方法來強制這部分由.NET 3.5編譯的代碼？或者存在另一個解決這個問題的建議？
如果您有源代碼，則應該添加更多錯誤日誌記錄或附加遠程調試器。根據你提供的信息，任何人都很難建議做什麼。 .NET 4 WPF應用程序與Windows XP兼容，因此您正在做的事情在代碼中不兼容（您沒有提供）。 –
通過運行eventvwr.exe查看Windows應用程序事件日誌 – spender
Windows XP不受支持，即使通過Microsoft **，您爲什麼關心該問題？ –
