I had an application on .Net Framework 4.0 and MVC2 running on Visual Studio 2010. I decided to move this application to Visual Studio 2015. So First I've upgraded it to MVC3 and then Opened it with Visual Studio 2015 and because the System.Web.MVC and some other dlls were missing. I installed Microsoft.AspNet.Mvc v3.0.50813.1 from Nuget. Now my application are being compiled successfully. But after running it, it displays this error:

我有一个在。net Framework 4.0和MVC2上运行于Visual Studio 2010的应用程序。我决定将这个应用程序转移到Visual Studio 2015。首先，我把它升级到MVC3，然后在Visual Studio 2015中打开它，因为System.Web。MVC和其他一些dll丢失了。我Microsoft.AspNet安装。Mvc v3.0.50813.1 Nuget。现在我的应用程序正在成功编译。但是在运行它之后，它会显示这个错误:

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

The file csc.exe exists in my Framework64 directory, but not in Framework directory.

csc的文件。exe存在于我的Framework64目录中，但不在框架目录中。

PS: I has some difficulty installing Visual Studio 2015 and I would prefer a solution doesn't need reinstalling Visual Studio.

PS:我在安装Visual Studio 2015时遇到了一些困难，我希望解决方案不需要重新安装Visual Studio。
