[release/7.0.2xx-xcode14.3] [dotnet] Fix linker path on Windows #18298
Conversation
When building from Windows, we need to pass the path to the illink assembly located on the Mac to the linker task. The educated guess we've been using is a bit fragile and has been getting us problems almost on each new .NET major release. On top of that, from .NET 8 the linker is in a separate NuGet package, so the assembly is no longer located in the SDK directory on the Mac. The fix is to follow the same approach we use to find the AOT compiler on the Mac by running a target that finds that information on the remote Mac, and brings it back to Windows, where it is cached and use across build. Created a new XamarinBuildTask class to share most of the code needed for this approach. Backport of dotnet#18285.
