You were the preprocessor we wished C# had natively
Removing PMCS requires these changes:
* Remove XamCore from src/
* Remove XamCore from tools/
* Remove XamCore from runtime/
* nint/nuint enum conversion
* _compat_ enum conversion
* NSAction conversion
* Hand fix single API incorrectly converted by PMCS to unbreak compatibility
- Due to a bug in PMCS, the nuint was incorrectly converted in this API.
- However, as that ship as sailed, we must "fix" it until XAMCORE_4_0
* Update readme
* Bump macios-binaries
- ApiTypoTest now enforces the rules defined here: https://github.com/xamarin/xamarin-macios/wiki/BINDINGS#availability-attributes-messages.
- Update all availability messages to follow new ApiTypoTest rules.
- Fix `IsObsolete` to handle ObsoletedAttribute.
- Don't apply rule 1 on Obsolete attribute.
- Allow to skip rule 4.
- Prevent use of OSX, OS X.
