Hello @sm-g and thanks for reporting that.
Indeed this is an FP - I'll add it to our backlog.

Same issue with WPF Delegates, for example

void application_Exit(object sender, ExitEventArgs e)

<Application
    x:Class="Kiosk.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:Kiosk"
    Exit="application_Exit"
    Startup="application_Startup"
    StartupUri="MainWindow.xaml">
    <Application.Resources />
</Application>

will compile to an error if application_Exit is changed to static.
