c# - 如何解决系统找不到指定文件的错误

Question

您好，我在Visual Studio专业版上设置应用程序时遇到问题。完成获取代码后，我单击该应用程序，但消息 pop ，就像您的应用程序中发生未处理的异常一样。我的框架是.NET Framework 4.5，我下载了MySQL连接器6.9.9版本。而且我不知道我的Windows 10 Pro的64位版本或框架以及MySQL连接器的设置是否错误。

错误消息显示:

有关调用的详细信息，请参见此消息的末尾
即时(JIT)调试，而不是此对话框。

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

 <configuration>

</configuration>

启用JIT调试后，任何未处理的异常
