'UnauthorizedAccessException' - 'Global\.net clr networking'

Question

我正在用户Guest下测试我的应用程序.它崩溃时出现以下错误.

'UnauthorizedAccessException' - 'Global.net clr networking'

现在,我知道我可以编辑机器上的安全策略,以允许在guest虚拟机下运行的CLR代码受到信任,但是应该在商业应用程序上做什么？

(签名,并添加CAS属性？)我目前正在阅读整个安全部分,但我有时间捏,所以任何正确方向的指针都会受到赞赏.

编辑:我已经跟踪问题使用类Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.如果包含此项,则会显示错误.我正在寻找要添加到清单或其他方式的东西,以便在安装/运行应用程序时,它会要求相应的权限.我不想要求用户亲自调用caspol或其他工具.

环境详细信息: - 应用程序正在使用.NET 3.0 - 操作系统是Vista

以下是这些内容的相关堆栈跟踪:

Answer 1

是否可以将其添加到app.config文件中？

<configuration>
   <system.net>
      <settings>
         <performanceCounters enabled="false" />
      </settings>
   </system.net>
</configuration>

这将指示网络类不要尝试创建在Guest帐户下不起作用的性能计数器.

上面的设置可以在.NET Framework 4及更高版本中运行,但是由于早期版本中的bug失败.
