Link to event from .xaml file in .fs file
I want to declare an event in a XAML file and then add a handler to fs.
The top of the XAML file will look like (MouseRightButtonDown):
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="AboutStack" MouseRightButtonDown="AboutStack_MouseRightButtonDown"
Title="About" SizeToContent="WidthAndHeight">
<StackPanel>...
The F # file contains:
open FsXaml
type MainWindow = XAML<"MainWindow.xaml", true>
let mainwnd = new MainWindow()
let wnd = mainwnd.Root
Is there an easy way to make a link?

Since there is no code, you cannot call the method from XAML, but it must be bound from the outside:
let AboutStack_MouseRightButtonDown args =
// do whatever you want, return unit
wnd.MouseRightButtonDown.Add(AboutStack_MouseRightButtonDown)
or for example
wnd.MouseRightButtonDown.Add(fun _ -> MessageBox.Show("Click!") |> ignore)
Another approach would be to use Model (DataContext) and bindings to create commands, for example Visual Studio Template for F # Windows App (WPF, MVVM)
