将.NET Standard类库转换为本地aar / jar [英] Convert .NET Standard class library to native aar/jar
问题描述
当前，我们正在开发一个.NET Standard类库，该库将由不同的Xamarin。*平台使用。
Currently, we are developing a .NET Standard class library that will be used by different Xamarin.* platforms.
我想知道是否有使用方法
I was wondering if there is a way to use the shared code in a native Android project (maybe produce an AAR/JAR file).
我需要此功能的原因是因为我们公司为其中一个提供了AAR客户（供本地Android项目使用），我们希望保留一个单一的来源库，而不是两个。
The reason I need this functionality is because our company provides an AAR to one of our customers (that is used by a native Android project), and we would like to keep a single source base instead of two.
预先感谢！

更新：
名称更改为 .NET Embedding，它位于此更新时为v0.4。
Update:
The name changed to ".NET Embedding" and it is at v0.4 at the time of this update.

- Installing .NET Embedding
您可以使用Mono的 Embeddinator- 4000
You can use Mono's Embeddinator-4000
它支持各种语言使用者，因此它以目标语言的惯用代码形式显示.NET代码。这是当前受支持的语言列表：
It supports various language consumers, so it surfaces .NET code as idiomatic code in the target language. This is the list of supported languages at present:
- Objective-C：将.NET映射到惯用目标-C API。
- Java：将.NET映射到惯用的Java API。
- C：将.NET映射到诸如C API的面向对象。
Embeddinator-4000是允许您现有的.NET代码（C＃，F＃等）的工具。
Embeddinator-4000 is a tool that allows your existing .NET Code (C#, F# and others) to be consumed from other programming languages and in various different environments.
Java当前处于macOS，Windows和Android的预览状态。
Java is currently in a preview state for macOS, Windows, and Android.
通过将--platform =命令行参数传递给embeddinator来选择平台。当前支持macOS，Windows和Android。
The platform is selected by passing the --platform= command-line argument to the embeddinator. Currently macOS, Windows, and Android are supported.

作为要求的一部分对于Android，您将需要 Xamarin.Android 7.4.99+和Android Studio 3+（Java 1.8），但是如果您要使用Xamarin和Java来构建Android应用， 。
As a part of the requires For Android you will need Xamarin.Android 7.4.99+ and Android Studio 3+ (Java 1.8) but if you are building Android apps with Xamarin and Java you would have those already.
注意：此工具位于预览中，因此，请检查未解决的问题并在需要时发布新内容。
Note: This tool is in Preview, so review the open issues and post new if needed.

注意：这不是反编译，而是将Mono的运行时嵌入到允许CIL代码，AOT（即iOS）或不要在其他语言/运行时中运行。
Note: This is not trans-compiling, but embedding Mono's runtime in a native package that allow CIL code, AOT'd (i.e. iOS) or not to run within a different language/runtime.
