我有一个使用net461引用运行的ASP.NET Core 1.0完整应用程序.现在我正在尝试添加另一个框架–netcoreapp1.0.为此,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,我收到此错误：

Failed to make the following project runnable: MVC6_Full_Version
(.NETCoreApp,Version=v1.0) reason: Expected coreclr library not found
in package graph. Please try running dotnet restore again.

要解决这个问题,我运行了dotnet restore命令,但没有运气.

然后,我添加了这个块：

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

添加此块后,我得到了一个不同的错误：

Code: NU1002 Description: The dependency Microsoft.NETCore.App 1.0.0
does not support framework .NETFramework,Version=v4.6.1.

基本上,我想在我的应用程序中添加两个引用 – .NET Framework 4.6.1和ASP.NET Core 1.0.

我该如何解决这个错误？

使用.NET Framework或.NET Core构建ASP.NET Core项目绝对是可能的.你真的很接近 – 只需要一些调整：

>删除运行时部分,除非您打算进行本机编译(有点不寻常)
>将对Microsoft.NETCore.App的引用放在netcoreapp1.0部分内的依赖项部分中.我测试了以下更改,它可以无错误地恢复和编译：

project.json

...

   "frameworks": {
      "net461": {

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

只有.NET Core需要Microsoft.NETCore.App依赖项,并且在此处添加它将确保在为该框架构建时可用.

此外,命令部分已被弃用,可以删除.
