编译器可执行文件C：\ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ csc.exe找不到

Question

我在Visual Studio 2010上运行的.Net Framework 4.0和MVC2上有一个应用程序。我决定移动这个应用程序到Visual Studio 2015.所以首先我已经升级到MVC3，然后用Visual Studio 2015打开它，因为缺少System.Web.MVC和其他一些dll。我从Nuget安装了Microsoft.AspNet.Mvc v3.0.50813.1。现在我的应用程序正在成功编译。但运行后，它显示此错误：

Compiler executable file C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe cannot be found. 

该文件csc.exe存在于我的Framework64目录中，但不存在于Framework目录中。

PS：我在安装Visual Studio 2015时遇到了一些困难，我宁愿一个解决方案也不需要重新安装Visual Studio。

堆栈跟踪：Visual Studio 2010中后，不支持
