Ошибка на netcoreapp1.1 при добавлении ссылки на netstandard1.6.1

Question

Я попытался обновить проект моего веб-сайта netcoreapp1.0 до netcoreapp1.1 и проекта DAL (netstandard1.6.1), но эта ошибка появляется, когда я пытаюсь добавить свой проект DAL в качестве ссылки на мой проект веб-сайта.

Вот проект.json из моих проектов:

Проект DAL (netstandard1.6.1)

{
  "version": "1.0.0-*",
  "dependencies": {
    "Microsoft.AspNetCore.Identity.EntityFrameworkCore": "1.1.0",
    "Microsoft.EntityFrameworkCore.SqlServer": "1.1.0"
  },
  "frameworks": {
    "netstandard1.6": {
      "imports": "dnxcore50",
      "dependencies": {
        "NETStandard.Library": "1.6"
      }
    }
  }
}

Answer 1

В вашем DAL project.json версия NETStandard.Library должна быть 1.6.1, например:

"frameworks": {
    "netstandard1.6": {
      "imports": "dnxcore50",
      "dependencies": {
        "NETStandard.Library": "1.6.1"
     }
   }
}
