解決錯誤“Microsoft.NETCore.App 1.0.0不支持框架.NETFramework，Version = v4.6.1”

Question

我有一個使用net461引用運行的ASP.NET Core 1.0完整應用程序。 現在我想添加另一個框架netcoreapp1.0 。 為此，我更新了我的project.json，如下所示：

{
   "userSecretsId":"",
   "version":"2.4.0-*",
   "buildOptions":{
      "emitEntryPoint":true,
      "preserveCompilationContext":true
   },
   "dependencies":{
      "Microsoft.ApplicationInsights.AspNetCore":"1.0.0",
      "Microsoft.AspNetCore.Authentication.Cookies":"1.0.0",
      "Microsoft.AspNetCore.Diagnostics":"1.0.0",
      "Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore":"1.0.0",
      "Microsoft.AspNetCore.Identity":"1.0.0",
      "Microsoft.AspNetCore.Identity.EntityFrameworkCore":"1.0.0",
      "Microsoft.AspNetCore.Mvc":"1.0.0",
      "Microsoft.AspNetCore.Mvc.TagHelpers":"1.0.0",
      "Microsoft.AspNetCore.Server.IISIntegration":"1.0.0",
      "Microsoft.AspNetCore.Server.Kestrel":"1.0.0",
      "Microsoft.AspNetCore.StaticFiles":"1.0.0",
      "Microsoft.EntityFrameworkCore":"1.0.0",
      "Microsoft.EntityFrameworkCore.SqlServer":"1.0.0",
      "Microsoft.Extensions.Configuration.CommandLine":"1.0.0",
      "Microsoft.Extensions.Configuration.FileExtensions":"1.0.0",
      "Microsoft.Extensions.Configuration.Json":"1.0.0",
      "Microsoft.Extensions.Configuration.UserSecrets":"1.0.0",
      "Microsoft.Extensions.Logging":"1.0.0",
      "Microsoft.Extensions.Logging.Console":"1.0.0",
      "Microsoft.Extensions.Logging.Debug":"1.0.0",
      "Microsoft.VisualStudio.Web.BrowserLink.Loader":"14.0.0",
      "Microsoft.VisualStudio.Web.CodeGenerators.Mvc":"1.0.0-preview2-final"
   },
   "tools":{
      "BundlerMinifier.Core":"2.0.238",
      "Microsoft.AspNetCore.Razor.Tools":"1.0.0-preview2-final",
      "Microsoft.AspNetCore.Server.IISIntegration.Tools":"1.0.0-preview2-final",
      "Microsoft.Extensions.SecretManager.Tools":"1.0.0-preview2-final"
   },
   "commands":{
      "ef":"EntityFramework.Commands",
      "web":"Microsoft.AspNetCore.Server.Kestrel"
   },
   "frameworks":{
      "net461":{

      },
      "netcoreapp1.0":{
         "imports":[
            "dotnet5.6",
            "portable-net45+win8"
         ]
      }
   },
   "runtimes":{
      "win10-x64":{

      },
      "win81-x64":{

      },
      "win8-x64":{

      },
      "win7-x64":{

      }
   },
   "publishOptions":{
      "exclude":[
         "**.user",
         "**.vspscc",
         "wwwroot",
         "node_modules"
      ]
   },
   "scripts":{
      "prepublish":[
         "npm install",
         "bower install",
         "gulp clean",
         "gulp min"
      ]
   }
}

修改project.json后，我收到此錯誤：

無法使以下項目可運行：MVC6_Full_Version（.NETCoreApp，Version = v1.0）原因：在包圖中找不到預期的coreclr庫。 請嘗試再次運行dotnet restore。

要解決這個問題，我運行了dotnet restore命令，但沒有運氣。

然后，我添加了這個塊：

"Microsoft.NETCore.App": {
  "version": "1.0.0",
  "type": "platform"
},

添加此塊后，我得到一個不同的錯誤：

代碼：NU1002描述：依賴Microsoft.NETCore.App 1.0.0不支持框架.NETFramework，Version = v4.6.1。

基本上，我想在我的應用程序中添加兩個引用 - .NET Framework 4.6.1和ASP.NET Core 1.0。

我該如何解決這個錯誤？

Answer 1

使用.NET Framework或.NET Core構建ASP.NET Core項目絕對是可能的。 你真的很接近 - 只需要一些調整：

• 刪除runtimes部分，除非您打算進行本機編譯（有點不尋常）
• 放置參考Microsoft.NETCore.App在dependencies 內部部分netcoreapp1.0部分。 我測試了以下更改，它可以無錯誤地恢復和編譯：

project.json

...

   "frameworks": {
      "net461": {

      },
      "netcoreapp1.0": {
         "dependencies": {
            "Microsoft.NETCore.App": {
               "type": "platform",
               "version": "1.0.0"
            }
         },
         "imports": [
            "dotnet5.6",
            "portable-net45+win8"
         ]
      }
   }

Microsoft.NETCore.App .NETCore.App依賴關系僅對.NET Core是必需的，在此處添加它將確保在為該框架構建時可用。

此外， commands部分已被棄用，可以刪除。

Answer 2

我通過更改以下內容引用.net 4.6.1中的.net核心類庫。

在嘗試從.net 4.6.1引用.net核心時出現此錯誤之前

固定：

原版的

    {
    "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.0",
      "type": "platform"
    },
    "Interop.SHDocVw.dll": "1.1.0",
    "Microsoft.mshtml.dll": "7.0.3300.1"
    },

    "frameworks": {
    //"net461": {},
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "portable-net45+win8",
        "net461"
      ]
    }
   },

    "scripts": {
    "prepublish": [ "bower install", "dotnet bundle" ]
    }
   }

更正

    {
     "dependencies": {
        "Interop.SHDocVw.dll": "1.1.0",
        "Microsoft.mshtml.dll": "7.0.3300.1"
     },

    "frameworks": {
        "net461": {
        },
        "netcoreapp1.0": {
        "dependencies": {
            "Microsoft.NETCore.App": {
            "type": "platform",
            "version": "1.0.0"
            }
        },
        "imports": [
            "dotnet5.6",
            "portable-net45+win8",
            "net461"
        ]
        }
    },

    "scripts": {
        "prepublish": [ "bower install", "dotnet bundle" ]
    }
}
