ASP.Net核心Web API生成错误 - MSB4019未找到导入的项目Microsoft.DotNet.Props . 确认<Import>中的路径

在我添加 Sqlite Reference （见下文）之后，我在 ASP.Net Core Web API Project 中收到以下错误，并且还将 project.json 中的 Microsoft.NETCore.App 依赖版本从 1.0.1 （正在运行）更改为 1.1.0 （这打破了构建时出现以下错误） .

错误MSB4019未找到导入的项目“C：\ Program Files \ dotnet \ sdk \ 1.0.1 \ Microsoft \ VisualStudio \ v14.0 \ DotNet \ Microsoft.DotNet.Props” . 确认声明中的路径是否正确，以及该文件是否存在于磁盘上 . Cities.API C：\ Shiva \ PluralSight \ Cities.API \ Cities.API.xproj 8

请不要将此标记为副本

• External VS2013 build error “error MSB4019: The imported project was not found”或

• External VS2013 build error “error MSB4019: The imported project was not found”

我查看了这些2并且它们适用于Visual Studio 2013而不是.Net Core版本，它具有不同的项目和配置文件结构 .

这是我的 projects.json

{
  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.1.0",
      "type": "platform"
    },

    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",

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

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

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

  "publishOptions": {
    "include": [
      "wwwroot",
      "web.config"
    ]
  },

  "scripts": {
    "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
  }
}

这是我使用新更新的 1.1.0 为 Microsoft.NETCore.App 依赖进行构建时的错误消息 . 注意：当我开始 " 时， 1.1.0 确实显示在intellisense下拉列表中，这意味着它出现在我的机器上 .
