Question

任何想法为什么我在Nuget安装Entity framework 6.1.3后收到以下错误？

错误通知：“项目foo栏中的依赖项EntityFramework 6.1.3 不支持框架.NETPlatform，Version = v5.4“

这是我的global.json（已编辑的个人资料）

{
  "version": "1.0.0-*",
  "description": foo bar Class Library",
  "authors": [ "foo bar" ],
  "tags": [ "" ],
  "projectUrl": "",
  "licenseUrl": "",
  "frameworks": {
    "net451": { },
    "dotnet5.4": {
      "dependencies": {
        "Microsoft.CSharp": "4.0.1-beta-23516",
        "System.Collections": "4.0.11-beta-23516",
        "System.Linq": "4.0.1-beta-23516",
        "System.Runtime": "4.0.21-beta-23516",
        "System.Threading": "4.0.11-beta-23516"
      }
    }
  },
  "dependencies": {
    "EntityFramework": "6.1.3"
  }
}

Answer 1

我通过删除此行 - “net451”：{} ,,然后将“dotnet5.4”替换为“net451”来解决。

Answer 2

我和EF7有同样的问题，我可以通过在我的EF库中的project.json中将dotnet54更改为netcore50来解决它，并且每个项目都取决于它。

Answer 3

我只是通过切割

解决了这个问题

"dependencies": { "EntityFramework": "6.1.3" }

依赖于.Net4.51

"net451": {
  "dependencies": {
    "EntityFramework": "6.1.3",
    "Microsoft.AspNet.Identity.Core": "2.2.1",
    "Microsoft.AspNet.Identity.EntityFramework": "2.2.1"
  }

最后看

    {
  "version": "1.0.0-*",
  "description": "EMS.Identity Class Library",
  "authors": [ "SamuelA" ],
  "tags": [ "" ],
  "projectUrl": "",
  "licenseUrl": "",
  "frameworks": {
    "net451": {
      "dependencies": {
        "EntityFramework": "6.1.3",
        "Microsoft.AspNet.Identity.Core": "2.2.1",
        "Microsoft.AspNet.Identity.EntityFramework": "2.2.1"
      }
    },
    "dotnet5.4": {
      "dependencies": {
        "Microsoft.CSharp": "4.0.1-beta-23516",
        "System.Collections": "4.0.11-beta-23516",
        "System.Linq": "4.0.1-beta-23516",
        "System.Runtime": "4.0.21-beta-23516",
        "System.Threading": "4.0.11-beta-23516"
      }
    }
  }
}

Answer 4

我通过手动编辑project.json文件快速修复了类似的问题。

注意：让我提一下，我的解决方案是Asp.net 5.0 Web应用程序，目标是DNX 4.5.1

是：

{
  "version": "1.0.0-*",
  "description": "DataLayer Class Library",
  "authors": [ "local-admin" ],
  "tags": [ "" ],
  "projectUrl": "",
  "licenseUrl": "",
  "frameworks": {
    "net451": { },
    "dotnet5.4": {
      "dependencies": {
        "Microsoft.CSharp": "4.0.1-beta-23516",
        "System.Collections": "4.0.11-beta-23516",
        "System.Linq": "4.0.1-beta-23516",
        "System.Runtime": "4.0.21-beta-23516",
        "System.Threading": "4.0.11-beta-23516"
      }
    }
  },
  "dependencies": {
    "EntityFramework": "6.1.3"
  }
}

我替换了框架部分并成为：

{
  "version": "1.0.0-*",
  "description": "DataLayer Class Library",
  "authors": [ "local-admin" ],
  "tags": [ "" ],
  "projectUrl": "",
  "licenseUrl": "",
  "frameworks": {
    "dnx451": { }
  },
  "dependencies": {
    "EntityFramework": "6.1.3"
  }
}

Answer 5

我遇到了同样的问题，然后我可以通过删除特定项目文件的obj文件夹来解决它。

EntityFramework 6.1.3不支持visual studio 2015上的框架.NETPlatform，Version = v5.4
