* Revert previous revert (9ba23946d1)
* Correctly fall back to Modern if tagless binding projects
* Rework binding tests to cover all supported configurations
* Add XM_FORCE_MSBUILD env variable for mmp/msbuild mac tests for easy local checking
- Fixes https://github.com/xamarin/xamarin-macios/issues/3608
- Refactor and clean up msbuild to be more consistent between binding and "normal" workloads
- Comment on the inconsistencies that are too large to fix in one PR
- Write some actual tests for binding projects to detect regressions
- Due to lack of redirect support these tests are only xbuild current, but I ran tests with msbuild to validate locally
- https://bugzilla.xamarin.com/show_bug.cgi?id=59474
- The idea is to force Full and Modern to expand facades the same way. That way, we get the same, working behavior.
- f79f2e4 was not sufficient, even though it matched XI, because of the difference between XI (and Modern) and what Full was doing.
- Some context:
PR #2685
And that was problematic because it was expanding the netstandard facades from `Microsoft.NET.Build.Extensions`
in the `ImplicitlyExpandNETStandardFacades` target.
But we want to build against XM's bundled facades *only*. So we disable the ns facades completely
by setting `$(ImplicitlyExpandNETStandardFacades) = false`.
But now we are in the situation where a XM/Full project referencing a ns project might fail to build
because of a missing `netstandard.dll` reference! And this same case was fixed for XM/Modern projects in
https://github.com/xamarin/xamarin-macios/pull/2643 . So, we enable the use of that for XM/Full projects too
through `Xamarin.Mac.msbuild.targets`.
- In some build cases this chunk of code:
<ItemGroup Condition=" '$(NoCompilerStandardLib)' == 'true' and '$(NoStdLib)' != 'true' ">
<!-- Note that unlike VB, C# does not automatically locate System.dll as a "standard library"
instead the reference is always passed from the project. Also, for mscorlib.dll
we need to provide the explicit location in order to maintain the correct behaviour
-->
<_ExplicitReference Include="$(FrameworkPathOverride)\mscorlib.dll" />
</ItemGroup>
would trigger and force us to use mscorlib from system mono. That does not work well.
- By setting FrameworkPathOverride, we can get the right mscorlib
- However, that ItemGroup happens outside of a target, so we must move our setting to match for it to take effect
- Significant changes to target file under msbuild, ImplicitFacade processing in particular
- Tests are disabled due to https://bugzilla.xamarin.com/show_bug.cgi?id=53164 where we can't tests local target files only global
- Requires a mono msbuild with 95ab657a90 for tests to pass
- Until then, this is a workaround:
sudo cp /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/msbuild/15.0/bin/Roslyn/System.Reflection.Metadata.dll /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/msbuild/15.0/bin/
