如何使我的受管NuGet软件包支持C ++ / CLI项目？ [英] How can I make my managed NuGet package support C++/CLI projects?

问题描述

当我使用C＃项目时，我已经制作了一个NuGet软件包。它在 lib / net40 目录中包含一个DLL，并将该DLL添加为参考。

I have made a NuGet package that works well when I use it from a C# project. It contains a DLL in the lib/net40 directory, and the DLL gets added as a reference.

现在NuGet支持C ++，我如何实际修改我的包，以便可以在C ++ / CLI项目中将DLL添加为托管引用？我找不到任何解释这个的教程。如果我尝试仅仅添加包，我会收到以下错误：

Now that NuGet supports C++, how do I actually modify my package so that the DLL can be added as a managed reference in a C++/CLI project? I can't find any tutorials explaining this. If I try to just add the package as is, I get the following error:

您正在尝试将此软件包安装到一个项目中目标'Native，Version = v0.0'，但是该软件包不包含与该框架兼容的任何程序集引用或内容文件。

You are trying to install this package into a project that targets 'Native,Version=v0.0', but the package does not contain any assembly references or content files that are compatible with that framework.

人们会认为解决方案是将文件放在lib / native下，但是根据 http://docs.nuget.org/docs/reference/support-for-native-projects ，那不受支持。另外，直接将DLL直接放在lib下似乎没有任何作用。

One would think that the solution is to put the files under lib/native, but according to http://docs.nuget.org/docs/reference/support-for-native-projects, that is not supported. Also, simply putting the DLL directly under lib doesn't seem to do anything.

显然，我应该用一个 .props 或 .targets 在build / native下的文件，但是我需要把这些文件放在哪里才能使其工作？

Apparently, I am supposed to do this with a .props or .targets file under build/native, but what do I need to put into those files to make this work ?

推荐答案

由于 Patrick O'Hara写道， NuGet不会为您更改C ++ / CLI项目。请参阅 GitHub问题NuGet / Home＃1121 - 无法将托管软件包安装到CLI项目中。但是，使用NuGet命令行实用程序 NuGet.exe ，您可以将NuGet下载并解压缩所需的软件包。

As Patrick O'Hara wrote, NuGet will not make changes to a C++/CLI project for you. See GitHub Issue NuGet/Home#1121 - Cannot install managed packages into a CLI project. However, using the NuGet command line utility, NuGet.exe, you can have NuGet download and unpack the desired package(s).

有一个完整的例子，这里是添加 OptimizedPriorityQueue 1.0.0在Visual Studio 2013 C ++ / CLI项目中：

For a complete example, here were steps that I took to add a reference to OptimizedPriorityQueue 1.0.0 in a Visual Studio 2013 C++/CLI project:

1. 如果尚未打开，请打开软件包管理器控制台（工具> NuGet软件包管理器>软件包管理器控制台）



2. 在软件包管理器控制台中，安装NuGet.CommandLine软件包：

1. Open the Package Manager Console if not already open (TOOLS > NuGet Package Manager > Package Manager Console).

2. In the Package Manager Console, install the NuGet.CommandLine package:

Install-Package NuGet.CommandLine

（注意：在撰写本文时，最新版本的NuGet.CommandLine是2.8.6，可能会有所不同）

(Note: As of this writing, the latest version of NuGet.CommandLine is 2.8.6. It may be different for you.)

在你的项目文件夹中，现在应该有一个 .nuget\packages.config 具有以下内容的XML文件：

Within your project folder, there should now be a .nuget\packages.config XML file with the following contents:

<？xml version =1.0encoding =utf-8？>
< packages>
< package id =NuGet.CommandLineversion =2.8.6/>
< / packages>


在文本编辑器（如记事本++）中，添加一个 package> 元素。在这种情况下，我添加了：

In a text editor such as Notepad++, add a <package> element for the desired package. In this case, I added:

<package id="OptimizedPriorityQueue" version="1.0.0" />

..在< packages> 元素。

打开命令提示符（我打开了一个VS2013 Developer命令提示符，但常规命令提示符应该可以正常使用。）

Open a command prompt (I opened a VS2013 Developer Command Prompt, but a regular command prompt should work.)

运行以下命令，更改版本号NuGet.CommandLine如果不同：

Run the following command, changing the version number of NuGet.CommandLine if different:

.\packages\NuGet.CommandLine.2.8.6\tools\NuGet.exe Install -NonInteractive -OutputDirectory packages .nuget\packages.config

对我来说，输出是：

Installing 'OptimizedPriorityQueue 1.0.0.0'.
Successfully installed 'OptimizedPriorityQueue 1.0.0.0'.
All packages listed in packages.config are already installed.

右键单击Visual Studio中的项目，然后选择属性。在常用属性>参考下，点击添加新参考… 按钮。

选择浏览左手边。添加引用对话框的确定​​和取消按钮旁边有一个浏览… 按钮。单击该按钮打开文件选择对话框。

导航到NuGet解压缩到您项目文件夹的包子目录的DLL，然后单击添加按钮。单击确定关闭添加引用对话框。

您现在应该能够在C ++ / CLI项目中使用程序集：

Right click on the project in Visual Studio and select Properties. Under Common Properties > References, click the Add New Reference… button.

Select Browse on the left hand side. Next to the Add Reference dialog's OK and Cancel buttons, there is a Browse… button. Click that to open a file selection dialog.

Navigate to the DLLs that NuGet unpacked to the packages subdirectory of your project folder and click the Add button. Click OK to close the Add Reference dialog.

You should now be able to use the assembly in your C++/CLI project:

using namespace Priority_Queue;

//...
