What does the pull request do?
Fixes the behavior described in #10946 whereby using
<ItemsControl Items="{Binding Foo}"
would result in aBinding
object being added to theItemsControl.Items
collection instead of resulting in a compile error.Depends on kekekeks/XamlX#85: this PR disallows invoking "collection behavior" for property setters when using attribute syntax.
Required adding a
Flyout.FlyoutPresenterClasses
setter. This property was previously buggy without the setter (see #10946 (comment)). Added tests for setting classes that I put in place when investigating this.Breaking changes
Can no longer add items to a collection in XAML using attribute syntax. This shouldn't have been possible before, but it's possible that someone was depending on it working.
