Fixes: https://github.com/xamarin/xamarin-macios/issues/8265
Usage of `System.Drawing` types in iOS binding projects are failing with:
error CS1069: The type name 'Color' could not be found in the namespace 'System.Drawing'.
This type has been forwarded to assembly 'System.Drawing.Common, Version=4.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'
Consider adding a reference to that assembly.
In 3a7bdc0, an `_AddExtraReferences` MSBuild target was added for iOS
and Mac projects, but mistakenly missing from binding projects.
I moved the `_AddExtraReferences` target to `Xamarin.Shared.targets`,
so it will be used for all project types.
I also updated a test, I could merely use `System.Drawing.Color` in
`StructsAndEnums.cs` to reproduce the failure.
Goals
* Reflect Apple nullability annotations in our bindings using C#8
* No warnings when building bindings
Non-Goals
* Update (add or fix) `[NullAllowed]` to match Apple headers (next phase)
* Make the generator or internal code fully nullable aware (`nowarn` is used)
Notes
* Apple's own annotations are not 100% accurate :(
* Where known issue exists we have _fixed_ our attributes to match reality :)
* We also do additional null-checks internally that might seems not required (better safe than sorry).
This has a couple of advantages:
* It makes it easier to add a catalyst version of these libraries (because it
becomes cumbersome to build for catalyst when the build rules assumes we're
building for both simulator and device).
* It makes it easier to create an xcframework of our libraries, because the
contents in an xcframework is split like this.
Fixes this test:
Xamarin.MTouch.AppAndExtensionWithBindingFramework: Expected execution to succeed, but exit code was 1, and there were 2 error(s): build app
error MT5210: Native linking failed, undefined symbol: _CLLocationCoordinate2DMake. Please verify that all the necessary frameworks have been referenced and native libraries are properly linked in.
error MT5202: Native linking failed. Please review the build log.
* Add a server mode, which launches a web server (and a web page) that can be
used to interactively run tests and view their results.
* Add support for running test assemblies in a today extension (generating a
new set of projects, similar to how we generate tvOS/watchOS projects based
on the iOS project, we now generate a today extension project in addition to
the tvOS and watchOS projects).
* Load all the different tests (and show them in the html report, although
they show up as 'ignored'), even for disabled/ignored tests. This makes
disabled/ignored tests more visible, and also makes it possible to actually
run them using the embedded web server.
* Add support for running tests on device. Tests will be executed on multiple
devices simulatenously (any connected devices will be used).
