当尝试从MVC3升级到MVC4时,"操作可能会破坏运行时的稳定性"

Question

Server Error in '/' Application.

对此进行故障排除有什么好处？我让调试逐步通过global.asax中的所有内容,并且没有错误.

这是一件非常奇怪的事情 - 提供的信息不足以重现它......所以只有一些可能导致您看到的内容：

• Intellitrace（将其关闭并查看是否有帮助）
• 使用任何“旧控件”（尤其是 V 1.1），将其注释掉并查看是否有帮助
• Trustlevel，更改[assembly: SecurityRules(SecurityRuleSet.Level1)]为 AssemblyInfo.cs 并查看是否有帮助

它也可能是.NET 4.5 运行时中的一个错误，它在安装时作为 .NET 4 运行时的直接替代品起作用，即使您的代码仅针对 .NET 4，也会使用它！

从链接的文章中，Microsoft 创建了针对 .Net 4.5/4.0 运行时的修复程序作为修补程序： http: //support.microsoft.com/kb/2748645
