Using a different way of subscribing as a work around is not really an option, since I may not be in control of the code that is doing the subscribing...

Would it be possible to make `ObservableObject.PropertyChanged` and `ObservableObject.PropertyChanging` virtual? That way a consumer could override them to use `DelegateWeakEventManager`.

@edsnider I believe the sample in this repo demonstrates the original behavior (not the crash), however I wasn't able to get it to build to confirm. So, here is a...

It looks like you put the certificate in a folder called `my_ca`, when it seems like you need to name the certificate file `my_ca`. From this page: https://developer.android.com/training/articles/security-config#certificates >__src__ a...

I think a similar issue might be causing #8840 _TranslationY does not work on Frame component_.

I just like to highlight one use for this that is nothing to do with unit testing (and nothing to do with mocking conceptually, even if a mocking framework might...

@hartez In #19794 you say this isn't exactly a bug. Does that mean it is intentional that `ContentView` (and `TemplatedView`) inherits from `Compatibility.Layout`?

`ToUIBarButtonItem` has gained an extra parameter. Both are optional so I'm not sure why it fails but that passing `false` as the second parameter should work. https://github.com/xamarin/Xamarin.Forms/blob/0a67f8b0a105fbf56b6ac704cfc283840a189817/Xamarin.Forms.Platform.iOS/Extensions/ToolbarItemExtensions.cs#L12 __EDIT__ Optional parameters...
