如何使我的受管NuGet包支持C ++ / CLI项目？

问题描述

我已经做了一个NuGet包，当我从一个C＃项目使用它工作得很好。它在 lib / net40 目录中包含一个DLL，并将该DLL添加为引用。

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.

NuGet支持C ++，我如何实际修改我的包，使得DLL可以作为C ++ / CLI项目中的托管引用添加？我找不到任何教程解释这个。如果我试图只是添加包作为，我得到以下错误：

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:

有人会认为解决方案是将文件放在lib / native下，但根据，不支持。此外，简单地将DLL直接放在lib下似乎没有做任何事情。

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 文件，但是我需要将这些文件放入哪些文件才能使此工作？

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， NuGet不会为您更改C ++ / CLI项目。请参见。但是，使用NuGet命令行实用程序 NuGet.exe ，您可以让NuGet下载并解压所需的软件包。

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).

对于一个完整的示例，这里是我添加一个参考到 OptimizedPriorityQueue 1.0.0：

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. 打开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：最新版本的NuGet.CommandLine是2.8.6，它可能会有所不同。）

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

在您的项目文件夹中，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="1.0" encoding="utf-8"?>
<packages>
  <package id="NuGet.CommandLine" version="2.8.6" />
</packages>

在Notepad ++等文本编辑器中，添加 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" />

.. within the <packages> element.

打开命令提示符（我打开了一个VS2013开发人员命令提示符，但正常的命令提示符应该可以正常工作。）

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

执行以下命令，将版本号更改为

cd 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.

在Visual Studio中右键单击项目，然后选择属性。在常用属性>参考下，点击添加新参考和翻译按钮。

左手边。在添加参考对话框的确定​​和取消按钮旁边，有一个浏览… 按钮。

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

您现在应该可以在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;

//...
