如何从.net Core项目中调用经典NetFramework库方法

Question

我有一个非常简单的asp.net核心项目和一个内置在。net框架4.6.1中的类库我已经导入了库在asp.net核心项目，但我不能使用它。如果在控制器中(例如)我写:

使用ClassLibrary1;

弹出提示:

namespace ClassLibrary1 WebApplication1。. Net Framework 4.6.1 -可用的web应用程序NetCoreApp,Version 1.0 -不可用

我如何在asp.net核心项目中使用我的类库对象和方法?

谢谢你的回复，但不适合我。

这是我的project.json

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

，这里是我的项目文件1

但是在home控制器中我得到这个错误2

什么错了吗?

你的库应该支持netcoreapp1.0或者你的网站应该支持net461(或两者)。更新您的项目。Json with:

"frameworks": {
    "net461": {
    },
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
            "version": "1.0.0",
            "type": "platform"
        }
      }
    }
  }
