I suggest we consider allowing ExtensionProperty=expr property setters in initializers.
For example
C(ExtensionProperty = [1;2;3])
Or for example to provide c# “add” pattern like support
type StackLayout with
member x.ChildrenInitializer with set (values : UIElement seq)=
values |> Seq.iter x.Children.Add
let layout = StackLayout (Orientation = StackOrientation.Horizonta,
ChildrenInitializer = [Entry(Placeholder = “Username”);Entry()])

This has now been completed for F# 4.0+, see dotnet/fsharp#17 and https://github.com/fsharp/FSharpLangDesign/blob/master/FSharp-4.0/ExtensionPropertyInitializersDesignAndSpec.md
