.Net Core v.1.1.0未找到

Question

我正在尝试使用.net Core类库项目中的EF Core对现有数据库进行逆向工程.

这是 project.json

{
  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.1.0",
      "type": "platform"
    },
    "Microsoft.EntityFrameworkCore.Design": "1.1.0",
    "Microsoft.EntityFrameworkCore.SqlServer": "1.1.0",
    "Microsoft.EntityFrameworkCore.SqlServer.Design": "1.1.0",
    "Microsoft.EntityFrameworkCore.Tools": "1.1.0-preview4-final"
  },

  "frameworks": {
    "netcoreapp1.1": {
      "imports": [
        "dotnet5.6",
        "portable-net45+win8"
      ]
    }
  }
}

这是我得到的错误:

PM> scaffold-dbcontext "data source=Server;Initial Catalog=Database;Integrated Security=true" Microsoft.EntityFrameworkCore.SqlServer -verbose
Build started...
Build succeeded.
The specified framework 'Microsoft.NETCore.App', version '1.1.0' was not found.
  - Check application dependencies and target a framework version installed at:
      C:\Program Files\dotnet\shared\Microsoft.NETCore.App
  - The following versions are installed:
      1.0.1
      1.1.0-preview1-001100-00
  - Alternatively, install the framework version '1.1.0'.
Process finished with non-zero exit code

这是我针对.Net的1.1.0.

如错误日志所示,您的计算机上没有安装1.1.0版本的.NET Core.该版本是scaffold-dbcontext工具所必需的,它是.NET Core CLI的一部分,不属于您的应用程序,因此不会使用您应用中的nuget软件包.

要安装.NET Core 1.1.0,请转到.NET Core Download页面并选择所需的x86/x64版本.之后,您将拥有新的"1.1.0"文件夹C:\Program Files\dotnet\shared\Microsoft.NETCore.App,这是.NET Core框架的默认位置.
