Question

我正在尝试启动并运行基本的ASP.NET MVC Core 1项目（来自aspnetcidev feed的软件包，DNX SDK 1.0.0-rc2-16551）。我为该项目运行Kestrel，但当我尝试导航到Home/Index时，我遇到了许多运行时错误：

Now listening on: http://localhost:5000
Application started. Press Ctrl+C to shut down.
fail: Microsoft.AspNetCore.Server.Kestrel[13]
  An unhandled exception was thrown by the application.
Microsoft.AspNetCore.Mvc.Razor.Compilation.CompilationFailedException: One or more compilation failures occurred:

等等。似乎Razor缺少BCL课程，但此时我不知道如何提供这些课程。

这是我的project.json：

{
   "version": "1.0.0-*",
   "compilationOptions": {
      "emitEntryPoint": true,
      "warningsAsErrors": true,
      "preserveCompilationContext": true
   },

   "tools": {
      "dotnet-publish-iis": "1.0.0-*",
      "dotnet-razor-tooling": "1.0.0-*"
   },

   "content": [
      "Areas",
      "Views",
      "wwwroot",
      "hosting.json",
      "config.json"
   ],

   "dependencies": {
      "Microsoft.AspNetCore.Diagnostics": "1.0.0-*",
      "Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore": "1.0.0-*",
      "Microsoft.AspNetCore.Hosting": "1.0.0-*",
      "Microsoft.AspNetCore.Mvc": "1.0.0-*",
      "Microsoft.AspNetCore.Mvc.Razor": "1.0.0-*",
      "Microsoft.AspNetCore.Mvc.TagHelpers": "1.0.0-*",
      "Microsoft.AspNetCore.Server.Kestrel": "1.0.0-*",
      "Microsoft.AspNetCore.Server.WebListener": "0.1.0-*",
      "Microsoft.AspNetCore.Session": "1.0.0-*",
      "Microsoft.AspNetCore.StaticFiles": "1.0.0-*",
      "Microsoft.Extensions.Logging.Console": "1.0.0-*"
   },

   "commands": {
      "web": "MyApp"
   },

   "frameworks": {
      "dnx451": { }
   },

   "exclude": [
      "wwwroot",
      "node_modules"
   ],
   "publishExclude": [
      "**.user",
      "**.vspscc"
   ]
}

这是我的global.json：

{
   "projects": [ "src" ],
   "sdk": {
      "version": "1.0.0-rc2-16551"
   }
}

当前的MusicStore示例应用程序对我不起作用（很多缺少的引用），所以这也没有多大帮助。

有没有人知道从哪里拿起？

要使用DNX的最新MVC RC2夜间版本，您必须引用名为Microsoft.AspNetCore.Mvc.Dnx的兼容包，并使用services.AddMvcDnx()方法调用ConfigureServices()。
