Question

我正在创建一个概念解决方案的证明，该解决方案将使用Entity Framework进行共享项目。我希望共享项目能够被UWP项目和.Net Core网站引用。我能够让网站引用该项目并正确使用Entity Framework Core。当我尝试让UWP应用程序使用相同的代码时，它会编译，但在运行时会失败。我也尝试使用NetStandard1.4和NetStandard1.6更改框架，但实体框架核心无法正常工作。

我的共享项目是.Net Core类库（不是VS中的实际共享项目类型）。

这是我运行UWP应用程序时遇到的错误。当我尝试创建一个继承自DbContext的新Context类时会发生这种情况：

发生了'System.IO.FileLoadException'类型的异常   mscorlib.ni.dll但未在用户代码中处理

其他信息：无法加载文件或程序集   'System.Runtime，Version = 4.1.0.0，Culture = neutral，   PublicKeyToken = b03f5f7f11d50a3a'或其依赖项之一。该   找到程序集的清单定义与程序集不匹配   参考。（HRESULT异常：0x80131040）

这是我对共享项目的project.json。

{
  "version": "1.0.0-*",

  "dependencies": {
    "Microsoft.EntityFrameworkCore.Sqlite": "1.0.0",
    "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final",

        "dotnet5.6",
        "portable-net45+win8"
      ]
    }

  }
}

这是UWP项目的project.json

Answer 2

我不确定UWP项目是否适用于.NET Core项目。也许您可以尝试将EF项目更改为可移植类库项目。

如何与.Net核心网站和UWP应用程序共享.Net核心项目？
