microsoft .net framework

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>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

答案：<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
     <system.windows.forms jitDebugging="true" />
  </configSections>
</configuration>
Try this!

其他：try add <system.windows.forms jitDebugging="true" /> 

上一个：.NET中有没有这样的控件？
下一个：.NET: 对路径"E:\C#Practice\OperateXML"的访问被拒绝。 刚学.NET, 运行下面的代码是遇到上面的问题。
