Hey there @kubaflo! Thank you so much for your PR! Someone from the team will get assigned to your PR shortly and we'll get it reviewed.

[albyrock87]

MAUI/Microsoft me, this gentleman and other developers are spending a lot of time for free trying to help you improve the platform and fix bugs.

This PR seems ready to be merged or at least reviewed since three weeks ago. I have another PR waiting since October, and many other developers are on the same situation.

If MAUI team needs more devs, please tell Microsoft to hire new developers.

Now, besides the complains, can we move on with this PR? Thanks.

Hey , thanks for your help, seems this changes to the LayoutExtensions are causing some unit tests to failing

https://dev.azure.com/xamarin/public/_build/results?buildId=109492&view=ms.vss-test-web.build-test-results-tab

[kubaflo]

@rmarinho I've fixed the tests

[hansmbakker]

@rmarinho / @albyrock87 / @StephaneDelcroix could you please have a new look at @kubaflo's code? He updated it based on your feedback, and it would really be helpful to have this issue fixed.

Please reabse as well. The tests are very red and we think we fixed some more tests recently. Hopefully. CI is a bit dodgy.

@kubaflo we have the same logical bug on the vertical constraint, would you mind fixing that too?

This for example impacts while using a portrait image with AspectFit put inside a smaller vertical space with VerticalPosition="Start": the image will overflow the container (which is wrong).

Thanks

			// But, if the element is set to fill vertically and it doesn't have an explicitly set height,
			// then we want the minimum between its MaximumHeight  and the bounds' height
			// MaximumHeight is always positive infinity if not defined by the user
			if (view.VerticalLayoutAlignment == LayoutAlignment.Fill && !IsExplicitSet(view.Height))
			{
				consumedHeight = Math.Min(bounds.Height, view.MaximumHeight);
			}
// ->
            else if (!IsExplicitSet(view.Height))
			{
				consumedHeight = Math.Min(bounds.Height, view.DesiredSize.Height);
			}
