9.0.0-preview.4.10690 | MAUI Releases

What’s Changed

Known issues:

XamlC Error with RelativeSource and x:DataType: When using RelativeSource bindings, you may encounter XamlC error XFC0045. To fix this issue, set x:DataType directly within the {Binding} expression. This will compile despite Visual Studio showing an error.

Command="{Binding Source={RelativeSource AncestorType={x:Type vm:MyViewModel}}, Path=SelectCommand, x:DataType=vm:MyViewModel}"
