发布时如何针对特定的 .NET Core 运行时? [英] When publishing how do I target specific .NET Core Runtimes?

问题描述

当我发布我的 .NET Core 应用程序时，它会输出一个带有以下子目录的 runtimes 目录:

When I publish my .NET Core app, it outputs a runtimes directory with the following sub-directories:

- publish/runtimes/
   - debian.8-x64/
   - fedora.23-x64/
   - fedora.24-x64/
   - opensuse.13.2-x64/
   - opensuse.42.1-x64/
   - osx/
   - osx.10.10-x64/
   - rhel.7-x64/
   - ubuntu.14.04-x64/
   - ubuntu.16.04-x64/
   - ubuntu.16.10-x64/
   - unix/
   - win/

在我的 CI/CD 服务器上，我使用以下命令发布我的应用程序:

On my CI/CD server I publish my applications with this command:

dotnet publish -c Release -o ..publish

我在项目文件中的发布设置如下:

My publish settings in the project file are the following:

• 目标框架:netcoreapp2.1
• 部署模式:依赖于框架
• 目标运行时:win-x64

我只打算在 Windows 2016 Server 上发布此应用程序，因此不需要 OSX/Linux/Unix runtimes 文件夹.更糟糕的是，在某些情况下，这些 runtimes 文件夹包含已知易受攻击的 dll，这会导致 OSA 扫描误报.

I only plan to publish this application on Windows 2016 Server so the OSX/Linux/Unix runtimes folders are not necessary. Worse in several cases these runtimes folders contain known vulnerable dlls which lead to false positive OSA scans.

有没有办法将项目配置为只输出win运行时文件夹?

Is there a way to configure the project to only output the win runtime folder?

更新

我已经尝试了@ahsteele 的建议，将 RID 添加到我的 csproj 文件的输出与我没有指定 RID 的输出相同.

I have tried the suggestions by @ahsteele and the output of adding the RIDs to my csproj files is the same as if I did not specify the RIDs.

当我运行 CI/CD 命令示例时

When I run CI/CD command example

dotnet publish -c Release -r win10-x86 -o ..publish

我相信它创建了一个独立的部署.我的发布目录从 55MB 到 120MB，从 237 个文件到 482 个文件.

I believe it creates a self-contained deployment. As my publish directory goes from being 55MB to 120MB and from 237 files to 482 files.

更新 2

我尝试为发布步骤指定我的启动项目，它构建的运行时目录更紧凑.

I have tried specifying my startup project for the publish step and it builds the run time directories to be more compact.

这是我正在运行的构建命令:

Here is the build command I am running:

dotnet publish .startupProject.csproj -c Release -o ..publish

这是输出:

- publish/runtimes/
   - unix/
   - win/

我的解决方案中的某些项目确实指定了 netstandard2.0，而有些则指定了 netcoreapp2.0.如果您不指定目标框架或特定的 csproj 文件，Microsoft 是否记录在任何地方，它将为您提供所有可能运行时的所有目标框架?

Some of the projects in my solution do specify netstandard2.0 and some specify netcoreapp2.0. Does Microsoft document anywhere that if you don't specify a target framework or a specific csproj file, it will give you all of the target frameworks for all of the possible runtimes?

推荐答案

您应该能够使用 dotnet publish -r 开关.来自 .NET Core RID 目录 - Windows RID Windows 10/Windows Server 2016 RID 是:

You should be able to specify your runtime with the dotnet publish -r switch. From the .NET Core RID Catalog - Windows RIDs the Windows 10 / Windows Server 2016 RIDs are:

• win10-x64
• win10-x86
• win10-arm
• win10-arm64

意思是你的 CI/CD 命令可以指定运行时:

Meaning that your CI/CD command can specify the runtime:

dotnet publish -c Release -r win10-x86 -o ..publish

或者，可以在 项目文件的元素:

Alternatively a single RID can be set in the <RuntimeIdentifier> element of your project file:

<RuntimeIdentifier>win10-x64</RuntimeIdentifier>

可以将多个 RID 定义为项目文件的 元素:

Multiple RIDs can be defined as a semicolon-delimited list in the project file's <RuntimeIdentifiers> element:

<RuntimeIdentifiers>win10-x64;win10-x86</RuntimeIdentifiers>
