Library that is platform-specific via selective compilation?
The proposed library would sit alongside cross-platform libraries in Xamarin apps for iOS and Android. However, it would include files with names like
MyLibraryFile.android.cs
MyLibraryFile.ios.cs
Each file would have platform-specific content, and all files would be visible in the solutions for each platform, i.e. in the solution for the Android app, under MyLibrary, you would also be able to see MyLibraryFile.ios.cs.
The contents of the library would be steered via the project file, which would have a structure as follows.
First, a list of target frameworks is set
<PropertyGroup>
<TargetFrameworks>Xamarin.iOS10</TargetFrameworks>
<TargetFrameworks Condition="'$(OS)' != 'Unix'">$(TargetFrameworks);MonoAndroid12.0</TargetFrameworks>
</PropertyGroup>
Then, the project file selects which .cs files to build based on the TargetFramework set in the app project.
<ItemGroup Condition="$(TargetFramework.StartsWith('MonoAndroid'))">
<Compile Include="**\*.android.cs"/>
</ItemGroup>
My question is, is this a recognised pattern?
I can't find anything about it.
