如何将 .Net Core 类库 (.NetStandard v1.5) 用于 .Net Framework 4.6.2 应用程序 [英] How can I use .Net Core Class Library (.NetStandard v1.5) into .Net Framework 4.6.2 Application

问题描述

根据

在包管理器控制台中，确保在顶部的下拉菜单中选择了包源和项目.

install-package [你的包名]

AFAIK，就目前而言，这是最好的.

According to Mapping the .NET Platform Standard to platforms .NET Platform Standard 1.5 have to be compatible with .NET Framework 4.6.2. I have tried to use it (make new .NET Platform Standard class library, then new .Net Framework 4.6.2 console application), but the library is not recognized. What I am doing wrong?

project.json in class library:

{
  "version": "1.0.0-*",

  "dependencies": {
    "NETStandard.Library": "1.5.0-rc2-24027"
  },

    "frameworks": {
        "netstandard1.5": {
            "imports": "dnxcore50",
            "buildOptions": { "embed": "true" }
        }
    }
}

解决方案

If you get the latest .net core RTM release and the Update 3 VS tooling, things are a little nicer than they were during the RC period. Still don't have easy project references from csproj referencing xproj - but, you can get things to talk by packing up the xproj output into a nuget package, then using the package manager to install that package. Also, you shouldn't need the imports on the framework, nor the dependency on netstandard.library, at least I don't. Here's how I've done it:

• Create a .cmd file which will package the nuget files and two copy the output files to the folder where the package manager is expecting them. Here's that script, I call it makeNuget.cmd:

  IF "%1" == "%2" (

  dotnet pack --no-build --configuration %1 -o ../%3

  xcopy %4 "...\%3lib\%5" /Y

  )

• Add a postbuild script in the project.json of the xproj to run the script

  "scripts": {
  "postcompile": [ "makeNuget.cmd %compile:Configuration% Release packages\%project:Name% %compile:OutputDir% %compile:TargetFramework%"
  ] }

This should leave you with a nuget package in the packages[projectName] folder at the root of your solution, with the binaries in the packages[projectName]lib[targetFramwork] folder

• Now, you need to add the packages folder as a package source, so first open the package manager console, then click the little gear to add a package source (or Ctrl+Q, package sources, Enter). Then click the add button, name this source, browse or type in the packages directory and hit ok.
• In the package manager console, make sure both your package source and project are selected in the drop downs at the top.
• install-package [your package name]

AFAIK, that's as good as it gets at the moment.
