针对特定依赖项 NuGet
[英]Target specific dependencies NuGet
问题描述
I have the following dependencies in my .nuspec file:
我的 .nuspec 文件中有以下依赖项：
<dependencies>
<group>
<dependency id="Dep1" version="2.4.11" />
<dependency id="Dep2" version="1.0.4" />
<dependency id="Dep3" version="1.0.4" />
<dependency id="Dep4" version="1.0.0" />
<dependency id="Dep5" version="1.0.4" />
<dependency id="Dep6" version="1.0.4" />
</group>
</dependencies>
I've created a local nuget server and I'm installing this NuGet package in a Xamarin Forms solution.我已经创建了一个本地 nuget 服务器，我正在 Xamarin Forms 解决方案中安装这个 NuGet 包。
The thing is that in the Android part of the solution it will install, but in the .netstandard part it will complain that Dep 4, 5, 6 are only for MonoAndroid (which is correct).问题是在解决方案的 Android 部分它将安装，但在 .netstandard 部分它会抱怨 Dep 4、5、6 仅适用于 MonoAndroid（这是正确的）。 I don't need the dep 4,5 and 6 in my .netstandard solution.我的 .netstandard 解决方案中不需要 dep 4,5 和 6。
NU1202: Dep4 1.0.0 is not compatible with netstandard2.0 (.NETStandard,Version=v2.0).
How can I separate dependencies per targetFramework?如何分离每个 targetFramework 的依赖项？ I've tried multiple variations of groups within the dependencies category, but nothing will solve this problem.我在依赖项类别中尝试了多种组变体，但没有任何方法可以解决此问题。

After thoroughly reading仔细阅读后
https://docs.microsoft.com/en-us/nuget/reference/nuspec#dependencies-element https://docs.microsoft.com/en-us/nuget/reference/nuspec#dependencies-element
https://docs.microsoft.com/en-us/nuget/reference/target-frameworks https://docs.microsoft.com/en-us/nuget/reference/target-frameworks
https://docs.microsoft.com/en-us/xamarin/cross-platform/app-fundamentals/nuget-manual https://docs.microsoft.com/en-us/xamarin/cross-platform/app-fundamentals/nuget-manual
it can be summed up to:可以总结为：
Version 2.0+
As an alternative to a single flat list, dependencies can be specified according to the framework profile of the target project using elements within .
Each group has an attribute named targetFramework and contains zero or more elements.
The element without a targetFramework attribute is used as the default or fallback list of dependencies.
Therefore in my case it would be:因此，就我而言，它将是：
<dependencies>
<group targetFramework="MonoAndroid10">
<dependency id="Dep1" version="2.4.11" />
<dependency id="Dep2" version="1.0.4" />
<dependency id="Dep3" version="1.0.4" />
<dependency id="Dep4" version="1.0.0" />
<dependency id="Dep5" version="1.0.4" />
<dependency id="Dep6" version="1.0.4" />
</group>
<group>
<dependency id="Dep1" version="2.4.11" />
<dependency id="Dep2" version="1.0.4" />
<dependency id="Dep3" version="1.0.4" />
</group>
</dependencies>
This way when I'm installing the package on the .netstandard project it will check the targetFramework and see that it's not MonoAndroid and it will fallback to the element without a targetFramework and use only Dep1, Dep2 and Dep3.这样，当我在 .netstandard 项目上安装包时，它会检查 targetFramework 并看到它不是 MonoAndroid，它将回退到没有 targetFramework 的元素，并且只使用 Dep1、Dep2 和 Dep3。 For the MonoAndroid10 project it will do the same and use all of them.对于 MonoAndroid10 项目，它将执行相同的操作并使用所有这些。
