Linux 将带有类库的.Net核心MVC应用程序部署到Ubuntu 16.04：

我想构建一个简单的.net core MVC应用程序，其中包含一个用于数据访问的类库，以了解如何在Linux上构建/部署/运行core。不像我希望的那么简单

编辑：如果有人感兴趣，这里有一份解决方案：

我组装了一个VirtualBox VM，带有Ubuntu服务器16.04，并按照以下说明安装了dotnet core：

我在VS 2015的主机（Win10）上安装了所有最新的必要位，并创建了一个带有MVC应用程序和名为“DataAccess”的单一类库的解决方案。这是EF Core使用他们最新的核心提供商与MySQL对话。当我运行/调试它时，它在Win10主机上完美地运行。调出数据，看起来很棒

主机和虚拟机上的“dotnet--version”提供了：

1.0.0-preview2-003121

但是，当我将其部署到Ubuntu VM时，在类库依赖项上出现以下错误：

Project corecrossplatform (.NETCoreApp,Version=v1.0) will be compiled because the version or bitness of the CLI changed since the last build

无论我运行“dotnet还原”还是“dotnet运行”，都会发生这种情况。说实话，我甚至不确定我是否正确部署了这个东西。文档不完整，我在猜测。我将项目文件夹“src\corecrossform”（包含bin、Program.cs、appsettings.json等）中的所有内容复制到VM上，这就是我在VM中执行“dotnet”命令的地方

DataAccess.json文件：

{
  "version": "1.0.0-*",

    "dependencies": {
        "Microsoft.EntityFrameworkCore": "1.0.0",
        "MySql.Data.Core": "7.0.4-IR-191",
        "MySql.Data.EntityFrameworkCore": "7.0.4-IR-191",
        "NETStandard.Library": "1.6.0"
    },

  "frameworks": {
    "netstandard1.6": {
      "imports": "dnxcore50"
    }
  }
}

MVC project.json：

{
  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.0",
      "type": "platform"
    },
    "Microsoft.AspNetCore.Diagnostics": "1.0.0",
    "Microsoft.AspNetCore.Mvc": "1.0.0",
    "Microsoft.AspNetCore.Razor.Tools": {
      "version": "1.0.0-preview2-final",
      "type": "build"
    },
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.0",
    "Microsoft.AspNetCore.StaticFiles": "1.0.0",

  },

    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final"
  },

  "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "portable-net45+win8"
      ]
    }
  },

  "buildOptions": {
    "emitEntryPoint": true,
    "preserveCompilationContext": true
  },

  "runtimeOptions": {
    "configProperties": {
      "System.GC.Server": true
    }
  },

  "publishOptions": {
    "include": [
      "wwwroot",
      "Views",
      "Areas/**/Views",
      "appsettings.json",
      "web.config"
    ]
  },

  "scripts": {
    "prepublish": [ "bower install", "dotnet bundle" ],
    "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
  }
}

需要注意的是：当我使用“dotnetnew”运行示例项目并恢复时，通过上面的教程链接运行，它运行良好

我错过了什么？另一个附带问题：将此类应用程序发布到Linux机箱的最佳方式是什么？我在这一点上接近了吗

多谢

编辑：整个下午我都在踢这匹死马，我比较了我在网上找到的一些与“NU1002”错误相关的注释，并生成了示例项目“dotnet new”。我尝试将project.json文件（MVC和classlib）的“framework”部分更改为以下内容，但没有成功…相同的错误：

"frameworks": {
    "netcoreapp1.0": {
        "dependencies": {
            "Microsoft.NETCore.App": {
                "type": "platform",
                "version": "1.0.0"
            }
        },
        "imports": [
            "dnxcore50",
            "dotnet5.6",
            "portable-net45+win8"
        ]
    }
}

编辑：非常感谢goaty：正如他在评论中指出的那样，复制整个解决方案并构建它，最终成功构建。但是，我无法运行它而不出错。它似乎无法恢复MySQL EF核心依赖项：

DataAccess

库存在于src/目录之外。因此，web项目无法找到引用。 我推荐这种结构

src/
|---DataAccess/
|---CoreCrossPlatform/

---

希望有帮助：）

我刚刚查看了您的解决方案。看起来在src/corecrossform文件夹中只有web项目。类库不在那里？@goaty-真奇怪。可能根本就没有拉链？重新提供了一份新的副本。谢谢。你的新上传说访问被拒绝：）@goaty-Ha！哇！已公开，请重试。另请注意：DataAccess项目中有一个“SQL”文件夹。我在其中加入了一个脚本，用于创建和植入mysql数据库和表，以进行测试。
