ASP.NET 核心 RC2 独立模型以进行跨平台项目

Question

我正在尝试将模型分离到它们自己的项目中，以便在使用新的 .net 核心 class 库的 xamarin 跨平台应用程序中使用。我遇到的问题是：

我的解决方案结构如下：

我的class库project.json如下：

{
  "version": "1.0.0-*",

  "dependencies": {
    "NETStandard.Library": "1.5.0-rc2-24027",
    "Microsoft.AspNetCore.Identity.EntityFrameworkCore": "1.0.0-rc2-final"
  },

  "frameworks": {
    "net451": { },
    "netstandard1.5": {
      "imports": [
        "dnxcore50",
        "portable-net452+win81"
      ]
    },
    ".netcoreapp1.0": {
      "imports": [
        "dnxcore50",
        "portable-net45+win8"
      ]
    }
  }
}

我在 Web 应用程序中引用了 class 库，但我不确定我是否正确分离了模型。我试图找到一个解决方案，但因为 ASP.NET 核心框架仍然很新，所以没有太多关于如何将模型分离到它自己的项目中的文档或指南。我希望有人可以提供一些关于如何实现这一目标的指导。

Answer 1

解决方案中的单个项目并不总是拥有您需要的所有参考资料，您可以像这样手动添加它们。

右键单击项目标题。
去添加 -> 引用 Screen cap
Go Assemblies（可能是基于依赖的COM）并选择必要的依赖Screen Cap

Answer 2

听起来好像您没有从 Web 项目到 class 项目的正确引用（或者，您缺少 using 语句。

要从您的 Web 项目引用 class 项目，请更新您的 Web 项目的 project.json 和类似于以下内容的依赖项：

"dependencies": {
    "Climing.Domain": {
        "version": "1.0.0-*",
        "target": "project"
     },
}

Answer 3

我发现解决方案很奇怪，它是一个不应该成为问题的命名空间问题。我确信底层 ASP.NET 核心 RC2 框架中某处存在错误，尽管我可能错了？

当我将 class 库中 ApplicationUser 的命名空间从 'Climbing.Web.Models' 更改为 'Climbing.Domain' 时出现问题 - 这是正确的命名空间。一旦我将它改回 'Climbing.Web.Models' 命名空间，问题就解决了。

编辑：深入研究后发现我没有在引用 ApplicationUser 的视图中更新命名空间。通过更新导入解决了这个问题。
