Nuget 包内容文件未复制到 .NET Core 项目 [英] Nuget package contentFiles not copied to .NET Core project

问题描述

我正在尝试将 Nuget 包中的内容文件提取到引用我的包的项目中.

基于

太棒了，我的照片和预期的一样.

现在是最后的非工作步骤.我在我的 .NET Core 2.1 项目中安装了这个 Nuget 包，但缺少图像.在我的项目的根目录中，无论在 obj 文件夹和 bin 文件夹中，都没有图像的痕迹.

我尝试关闭并重新打开 Visual Studio，如某些评论中所述，但这并没有解决问题.

我也尝试将我的 .NET Core 项目样式更改为 PackageReference 但同样，这并没有解决问题

<属性组><OutputType>Exe</OutputType><TargetFramework>netcoreapp2.1</TargetFramework><RestoreProjectStyle>PackageReference</RestoreProjectStyle></PropertyGroup><项目组><PackageReference Include="ContentFilesExample";版本=1.0.0"/></项目组><项目组><无更新=appsettings.json"><CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory></无></项目组></项目>

那我做错了什么?.NET Core 真的支持 Nuget 包中的内容文件吗?

谢谢

解决方案

nupkg 应该有 contentFiles/ 目录:

安装到netcore项目:

它不会是消费项目中的松散文件，它会是您构建项目时的EmbeddedResource:

I'm trying to extract content files from a Nuget package to a project referencing my package.

Based on Justin Emgarten's comment

Packages.config projects use the content folder

Project.json/PackageReference/NETCore SDK projects use the contentFiles folder

So ok great, I created a .NET Core 2.1 Console Application project and followed the NuGet ContentFiles Demystified blog post which was written in 2016 at the time of project.json but should still work nowadays.

I created an image at c:devContentFilesExamplecontentFilesanyanyimagesdnf.png then created a c:devContentFilesExampleContentFilesExample.nuspec file and copy pasted the content:

<?xml version="1.0"?>
<package>
    <metadata minClientVersion="3.3.0">
        <id>ContentFilesExample</id>
        <version>1.0.0</version>
        <authors>nuget</authors>    <!-- The NuGet team authored this package -->
        <owners>nuget</owners>      <!-- The NuGet team owns this package -->
        <requireLicenseAcceptance>false</requireLicenseAcceptance>
        <description>A content v2 example package.</description>
        <tags>contentv2 contentFiles</tags>
        <!-- Build actions for items in the contentFiles folder -->
        <contentFiles>
            <!-- Include Assets as Content -->
            <files include="**/images/*.*" buildAction="EmbeddedResource" />
        </contentFiles>
    </metadata>
</package>

Then I generated the Nuget package with the command nuget pack ContentFilesExample.nuspec and opened it using Nuget Package Explorer

Great my picture is there as expected.

And now the final non-working step. I install this Nuget package in my .NET Core 2.1 project but the image is missing. No trace of the image in the root directory of my project, neither in the obj folder nor in the bin folder.

I tried to close and re-open visual studio as stated in some comments somewhere but that didn't solve the issue.

I also tried to change my .NET Core project style to PackageReference but again, this didn't solve the issue

<Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>netcoreapp2.1</TargetFramework>
        <RestoreProjectStyle>PackageReference</RestoreProjectStyle>
    </PropertyGroup>

    <ItemGroup>
        <PackageReference Include="ContentFilesExample" Version="1.0.0" />
    </ItemGroup>

    <ItemGroup>
        <None Update="appsettings.json">
            <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
        </None>
    </ItemGroup>

</Project>

So what am I doing wrong? Are content files in Nuget packages really supported by .NET Core?

Thank you

解决方案

nupkg should have contentFiles/ directory:

Install to netcore project:

It won't be a loose file in the consuming project, it will be an EmbeddedResource when you build the project:
