无法让 Razor MVC 在 Mono 上工作

Question

我正在通过这里的教程来构建一个 ASP.NET MVC 网站：http://www.asp.net/mvc/overview/getting-started/introduction/adding-a-view。我使用的不是 MSVC，而是 MonoDevelop，因为我使用的是 Linux 系统。

当我尝试将 Razor 视图添加到我的 HelloWorld 控制器的 Index 函数时遇到了一些问题。现在，Views/HelloWorld/Index.cshtml 的代码是这样的：

<h2>Index</h2>

<p>Hello from our View Template!</p>

Controllers/HelloWorldController.cs 的Index() 函数的代码是这样的：

// GET: /HelloWorld/
public ActionResult Index()
{
    return View();
}

但是当我转到http://127.0.0.1:8080/HelloWorld/ 时，我收到了 500 错误。它正在返回此信息：

System.InvalidOperationException
Could not locate Razor Host Factory type: System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35

Description: HTTP 500.Error processing request.
Details: Non-web exception. Exception origin (name of application or object): System.Web.WebPages.Razor.

Answer 1

在我的Web.config 文件中，我必须将<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc... 的version 标记从5.2.0.0 设置为5.2.3.0 以匹配我的NuGet 包版本。
