F# and dynamically loaded WPF, animation ok when interactive not when compiled
f#testing

I am testing a dynamic loader for XAML taken from Vladimir Matveev's blog
[link:v2matveev.blogspot.com]

The demo XAML code produces a window with
a Rectangle which has animated effects triggered by its Loaded event
a Button whose click handler is set in F#

In interactive mode everything works fine.
In compiled mode,
the Button works
but the Rectangle animation does not start.

Here is the main part of the code for both versions

type MainWindow() as this =
    inherit FsUiObject<Window>(Path.Combine(__SOURCE_DIRECTORY__, "MainWindow.xaml"))
 
    [<DefaultValue>] 
    [<UiElement("run")>]
    val mutable runButton : Controls.Button
 
    [<DefaultValue>]
    [<UiElement>]
    val mutable text : Controls.TextBox
 
    let clickHandler _ =
        let txt = this.text.Text
        MessageBox.Show(this.UiObject, txt) |> ignore
    do
        this.runButton.Click.Add(clickHandler)

let window = new MainWindow()

#if INTERACTIVE
   window.UiObject.ShowDialog() |> ignore
#endif  

#if COMPILED
  window.UiObject.Loaded.Add(fun _ -> 
     window.UiObject.ShowDialog() |> ignore )

 [<STAThread()>]  
 do 
    let app =  new Application() in
    app.Run(window.UiObject) |> ignore
#endif

Any ideas?

.

What's the purpose of the Loaded event handler? What happens if you remove it?

That works!

Thanks very much.

I had put that line in yesterday because until I did the window was not appearing at all,
something else must have changed since then.

I will put my next F# / WPF issue in a new post.
