Can't access interface properties

See original GitHub issue

Describe the bug Accessing many properties of interfaces exposed by Avalonia are not possible since #11062 with no alternatives.

To Reproduce Calling window.PlatformImpl?.DesktopScaling or any property of IPlatformImpl is not possible. Basically any interface that has suffix Impl cannot be used anymore, even when exposed from a public property.

I understand now that these changes were intentional, and I don’t mind the change of hiding these interfaces. I think that if you should change these public properties to private as well, e.g. PlatformImpl as it’s super confusing for users to have access to a property with instance that has zero accessible members.

I think this may be unintentional, since IWindowBaseImpl, ITopLevelImpl, are public interfaces

Nope, that’s the problem - they’ve always been considered by us to be unstable interfaces, but because we’ve never enforced any sort of access control on them, people have been using them as public interfaces without realizing (and these interfaces are old [^1] and by this point incredibly hacked together). We have our hands tied when making changes to Avalonia because of this.

Having said that, we’re listening to feedback and will adjust our approach based on that, they’re preview releases for a reason after all 😉

[^1]: Yep, that’s pre-0.0.1-alpha
