c# - ASP.NET Core 1.0 RC2 中的 "The type or namespace name could not be found"

Question

我目前正在尝试 ASP.NET Core 1.0 RC2。我将其创建为 .NET Framework 项目(而不是 .NET Core 项目)，并使用 .NET Framework 4.5 通过项目引用添加了对我们的 Models 库的引用:

"frameworks": {
  "net46": {
    "dependencies": {
      "Project.Core": {
        "target": "project"
      },
      "Project.DataAccess": {
        "target": "project"
      },
      "Project.Encryption": {
        "target": "project"
      },
      "Project.Models": {
        "target": "project"
      },
      "Project.Resources": {
        "target": "project"
      }
    }
  }
},

现在向我的 View 添加模型指令时，出现以下错误:

@model System.Collections.Generic.List<Project.Models.User>

The type or namespace name 'Project' could not be found (are you missing a using directive or an assembly reference?)
    public class _Views_Home_Index_cshtml : Microsoft.AspNetCore.Mvc.Razor.RazorPage<System.Collections.Generic.List<Project.Models.User>>
The type or namespace name 'Project' could not be found (are you missing a using directive or an assembly reference?)
        public Microsoft.AspNetCore.Mvc.Rendering.IHtmlHelper<System.Collections.Generic.List<Project.Models.User>> Html { get; private set; }

它还在智能感知中显示:无法解析标记“Project.Models.User” 和无法解析符号“model”

我添加了一个项目引用，添加了一个using语句......仍然出现这个错误。这是为什么？

这是 RC2 中的错误 with an open issue . workaround在对我有用的问题讨论中:

services.AddMvc()
.AddRazorOptions(options =>
{
    var previous = options.CompilationCallback;
    options.CompilationCallback = context =>
    {
        previous?.Invoke(context);
        context.Compilation = context.Compilation.AddReferences(MetadataReference.CreateFromFile(typeof(MyClass).Assembly.Location));
    };
    });

在您的示例中，您需要为 Project.Models.User 执行此操作。

不确定是否4.6.1 and Update 2 is needed for both projects ，我只尝试过。
