找不到导入的项目DotNet.Props

Question

有人请。任何人。过去两天我一直在为这个问题烦恼。我已经阅读了其他相似的问题。但它们并不准确。

错误消息是：     导入的项目

＆＃34; C：\ PROGRAMFILES \ DOTNET \ SDK \ 1.04 \的Microsft \ VisualStudio的\ v14.0 \ DOTNET的\ Microsoft.DotNet.Props＆＃34;没找到。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。

我正在尝试在安装Visual Studio 2017之前运行使用Visual Studio Express For Web 2015开发的Angular2 ASP.NET核心应用程序。我认为问题是该程序正在寻找.NET的一个版本以某种方式被删除的核心。这是我的proj.json

这是我在尝试仅打开应用程序时收到的错误消息的屏幕截图：

以下是尝试运行程序时控制台中的错误消息：

我很感激你的指导。 谢谢， CM

要在VS 2015中继续使用基于project.json的项目，您需要在解决方案级别（global.json或以上的目录层次结构）添加具有以下内容的project.json文件：< / p>

{
  "sdk": {
    "version": "1.0.0-preview2-1-003177"
  }
}

将1.0.0-preview2-1-003177替换为您计算机上安装的最新1.0.0预览版2 - 您可以将此版本作为C:\Program Files\dotnet\sdk的子文件夹找到。
