Compiled bindings in .NET Maui 9, pass the getter as a parameter?

[JohnHDev]

Hi, I am investigating the use of compiled bindings in a small fluent framework Ive created. Given the following code that uses a compiled binding:

        var label = new Label();
        label.SetBinding(Label.TextProperty, static (IViewModel m) => m.Date);

I want to pass a static function to my own fluent function like this:

        Content = new Label()
            .TextBinding(static (IViewModel m) => m.Date)
            .BackgroundColor(Colors.Red);

The code for the TextBinding method looks like this:

    public static Label TextBinding<TSource, TProperty>(this Label self, Func<TSource, TProperty> getter)
    {
        self.SetBinding(Label.TextProperty, getter);
        return self;
    }

But I get the following error:

        error BSG0002: The getter must be a lambda expression

The error is quite clear, so was thinking I might need to look at the codegen to see how that is implemented. Before I do that I wanted to check if Ive missed anything.

It might be Ive just had too much turkey at this point to see the wood for the trees. 🌲

(I have simplified the code above massively to get to a small example of what Im trying to achieve)
