C# 将Roslyn与.net 4.5.1上的MVC5、Web API一起使用

我有个问题）

我的参与人是iis7.5，net。框架4.5.1，asp.net（mvc5，web api） 我还想在我的项目中使用Roslyn（C#6.0）

我添加nuget包：

1)Microsoft.Net.Compilers
2)Microsoft.CodeDom.Providers.DotNetCompilerPlatform

然后发布解决方案。发布成功，但不幸的是，当我导航到主页时出现编译错误（-2146232576）

ASP.NET :4.0.30319.18446

我想知道怎么了？是否必须安装.net 4.6

我已经找到了一些相关的解决方案，但是没有其他更优雅的方法来解决这个问题吗
