> ASP.NET 4

我已经升级了我的整个代码库,以便与大量的新玩具保持同步.现在它是：

> ASP.NET 4.5
> MVC 4(Razor 2)
>实体框架5
> Azure配置设置为osFamily =“3”
> Azure SDK 1.8(存储客户端库精心升级到2而不是1.7)

当我在分段中访问该站点时,我得到一个黄色的死亡屏幕,说无法找到编译器可执行文件csc.exe.我的问题是为什么？

它在本地工作正常,在发布模式下也是如此.我转发了,实例肯定运行Windows Server 2012(因此.NET 4.5 ??我已经看到它很难说,因为.NET 4.5替换了.NET 4文件夹中的.NET 4程序集).

根据响应头,它肯定运行IIS 8但有趣的是它声称X-ASPNET-VERSION是4.xxxx.对于ASP.NET 4站点来说这是正常的吗？

更新：

我针对.NET 4框架并将osFamily更改为2,现在可以正常工作了.所以我现在怀疑我有一个使用.NET 3.5或2的第三方程序集(事实上我确定我这样做)但是当针对的.NET框架高于导入程序集中引用的.NET框架时,会使用更高版本的框架??

osFamily =“3”只安装了.NET 4和4.5,所以我猜这是错误的原因,但我对目标的事情不对吗？我想使用osFamily =“3”我该怎么办？
