使用.NET Core CLI，在以完整框架为目标时添加对本地DLL的引用 [英] Using .NET Core CLI, add a reference to a local DLL when targeting the full framework

问题描述

在使用.NET Core工具构建新的控制台应用程序且仅针对.NET 4.5.1框架时，我想知道如何引用本地的，未签名的CLR 4.0程序集.

I would like to know how to reference a local, unsigned CLR 4.0 assembly, when building a new Console application using the .NET Core tools and only targeting the .NET 4.5.1 framework.

我在Windows 10计算机上执行了以下操作:

I did the following on a Windows 10 machine:

1. 使用以下代码创建一个新的MyLibrary.cs:

using System;
namespace MyNamespace
{
  public class MyLibrary
  {
    public static void SayHi()
    {
      Console.WriteLine("Hi");
    }
  }
}

1. 使用csc /t:library MyLibrary.cs编译以上内容.

创建一个新文件夹和一个.NET Core项目.

Create a new folder and a .NET Core project.

mkdir MyConsoleApp
cd MyConsoleApp
dotnet new

1. 将自动生成的project.json文件编辑为目标.NET 4.5.1.

{
  "version": "1.0.0-*",
  "buildOptions": {
    "debugType": "portable",
    "emitEntryPoint": true
  },
  "dependencies": {},
  "frameworks": {
    "net451" : { } 
  }
}

1. 测试项目是否已构建并运行.是的.

dotnet restore
dotnet build
bin\Debug\net451\MyConsoleApp.exe

1. 编辑Program.cs以调用MyLibrary.dll中的代码.

public static void Main(string[] args)
{
    Console.WriteLine("Hello World!");
    MyNamespace.MyLibrary.SayHi();
}

这就是我被困住的地方.

And this is where I am stuck.

我将DLL放在哪里以及将什么放入project.json ，以便可以在程序集中调用代码?

Where do I place my DLL and what do I put in the project.json so that I can call code in my assembly?

推荐答案

旧版DLL必须包装在nuget包中.我以前从未创建过nuget包.在这种情况下，这是我的操作方式:

The legacy DLL must be wrapped in a nuget package. I have never created a nuget package before. Here is how I did it in this case:

1..准备为旧版DLL创建nuget程序包:

1. Prepare to create a nuget package for the legacy DLL:

cd..
mkdir lib\net40
move MyLibrary.dll lib\net40
nuget spec -AssemblyPath lib\net40\MyLibrary.dll
// which generates a MyLibrary.dll.nuspec XML file.

2..填写或删除nuspec文件中的字段:

2. Fill in or delete fields in the nuspec file:

<?xml version="1.0"?>
<package >
  <metadata>
    <id>MyLibrary.dll</id>
    <version>1.0.0</version>
    <authors>Wallace Kelly</authors>
    <description>My test library.</description>
  </metadata>
</package>

3.打包nuget软件包并将其移至nuget文件夹结构中:

3. Pack the nuget package and move it into the nuget folder structure:

nuget pack MyLibrary.nuspec -OutputDirectory lib\net40
// which generates a MyLibrary.dll.1.0.0.nupkg

4..创建一个新的nuget-source文件夹:

4. Create a new nuget-source folder:

nuget init lib nuget-source

5..在项目文件夹(例如MyConsoleApp)中，使用以下命令创建一个新的nuget.config文件:

5. In the project folder (e.g, MyConsoleApp), create a new nuget.config file with the following:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
</configuration>

6..将本地nuget-source文件夹添加到nuget的源列表中:

6. Add your local nuget-source folder to the list of nuget's sources:

nuget sources add -Name "Local Source" -Source "c:\temp\dotnet-core-test\nuget-source" -configfile nuget.config

在project.json文件中，将依赖项添加到旧版DLL.

In the project.json file, add a dependency to the legacy DLL.

"dependencies": {
  "MyLibrary.dll": "1.0.0"
}, 

7..这时，您应该能够还原，构建和运行项目.

7. At this point, you should be able to restore, build, and run the project.

dotnet restore
dotnet build
dotnet run
