我在使用WebApi但未使用MVC的项目中遇到类似的问题，后来使用以下方法添加MVC:

I had a similar Problem with a Project using WebApi but not MVC and used the following Approach to add MVC later on:

• 我使用块金将Microsoft.AspNet.Mvc以及Microsoft.AspNet.Web.Optimization添加到了项目中
• 我向App_Start文件夹添加了一个RouteConfig文件(由MVC模板创建)，并在Global.asax.cs类中执行了方法RegisterRoutes，再次对应于一个新的MVC项目.这允许控制器被调用.
• 我添加了控制器(主页)和新视图(Index.cshtml).添加视图创建了Shared/_Layout.cshtml和_ViewStart.cshtml文件

启动项目后，它导致我收到以下错误消息:

Once I started the project, it resulted in me getting the following error message:

视图必须派生自WebViewPage或WebViewPage< TModel>

• 研究了问题之后，我在
  • After researching the problem I found an article on msdn describing a solution. The missing component is the Web.config file from the Views folder. Again you can copy a file from an existing MVC project
  • In the Web.config file I had to remove the old projects default namespace from the System.web.webPages.razor section and replace it with my own Default Namespace

  完成后，我可以使用标准的MVC控制器.

  And with that done I could use the standard MVC Controllers.
