Visual studio 2010 在Visual Studio 2010中获取HTTP错误500.0

尝试使用Visual Studio运行.Net MVC3应用程序时出现HTTP错误500.0-内部服务器错误。这是在我被迫将Silverlight升级到版本5后突然发生的。该应用程序是带有.Net Framework 4的MVC3

当我使用Visual Studio Development Server运行应用程序时，会出现以下YSOD错误屏幕：

   Server Error in '/' Application.

我通过删除解决方案中每个项目（包括主MVC项目和所有Silverlight项目）的bin文件夹中的所有内容，然后重新构建来解决这个问题。在这上面浪费了太多时间
