从ASP.NET 5引用.NET 4.6项目会导致生成错误 [英] Referencing a .NET 4.6 project from ASP.NET 5 causes build error

问题描述

在我的ASP.NET 5 RC1项目(仅针对dnx46)中，我试图添加对目标为.net 4.6的(经典)类库项目的引用.

In my ASP.NET 5 RC1 project (targeting only dnx46) I'm trying to add a reference to a (classic) Class Library project targeting .net 4.6.

在构建时出现此错误: ... \ MSBuild \ 14.0 \ bin \ Microsoft.Common.CurrentVersion.targets(1819,5):警告MSB3274:无法针对主引用"... \ ClassLibrary1.dll"进行解析，因为它是针对.\ ClassLibrary1.dll"构建的. NETFramework，Version = v4.6框架.这是当前目标框架".NETFramework，Version = v4.5.1"的更高版本.

I get this error at build time: ...\MSBuild\14.0\bin\Microsoft.Common.CurrentVersion.targets(1819,5): warning MSB3274: The primary reference "...\ClassLibrary1.dll" could not be resolved because it was built against the ".NETFramework,Version=v4.6" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.5.1".

为什么会这样?我的ASP.NET 5项目没有针对4.5.1.根据project.json文件，它仅针对dnx46.我在任何地方都找不到.net 4.5.1的提法.

Why is this happening? My ASP.NET 5 project isn't targeting 4.5.1. According to the project.json file it's only targeting dnx46. I can't find any mention of .net 4.5.1 anywhere.

这是我的WebApplication项目的project.json:

Here's the project.json for my WebApplication project:

{
  "version": "1.0.0-*",
  "compilationOptions": {
    "emitEntryPoint": true
  },

  "dependencies": {
    "Microsoft.AspNet.IISPlatformHandler": "1.0.0-rc1-final",
    "Microsoft.AspNet.Server.Kestrel": "1.0.0-rc1-final"
  },

  "commands": {
    "web": "Microsoft.AspNet.Server.Kestrel"
  },

  "frameworks": {
    "dnx46": {
      "dependencies": {
        "ClassLibrary1": "1.0.0-*"
      }
    },
  },

  "exclude": [
    "wwwroot",
    "node_modules"
  ],
  "publishExclude": [
    "**.user",
    "**.vspscc"
  ]
}

这是包装"过程为我的ClassLibrary项目创建的project.json:

And here's the project.json that the "wrapping" process creates for my ClassLibrary project:

{
  "version": "1.0.0-*",
  "frameworks": {
    "net46": {
      "wrappedProject": "../../ClassLibrary1/ClassLibrary1.csproj",
      "bin": {
        "assembly": "../../ClassLibrary1/obj/{configuration}/ClassLibrary1.dll",
        "pdb": "../../ClassLibrary1/obj/{configuration}/ClassLibrary1.pdb"
      }
    }
  }
}

推荐答案

如果使用VS 2015 Update 1进行构建，警告仍然存在，但Web应用程序运行良好，可以从.net4.6程序集中调用方法.

The warning is still there if built using VS 2015 Update 1, but web app works well and can call a method from .net4.6 assembly.
