On Windows I can set a window to be in foreground using this code:
[DllImport("User32.dll")]
public static extern bool SetForegroundWindow(IntPtr hWnd);
...
var process = Process.Start(start);
IntPtr handle = process.MainWindowHandle;
SetForegroundWindow(handle);
How can this be achieved on macos with .net 6?
In AvaloniaUI you can do this in cross-platform fashion using Window.Topmost.
This is how you would create a window in XAML that will always be on top:
<Window xmlns="https://github.com/avaloniaui"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:vm="using:AlwaysOnTop.ViewModels"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" d:DesignWidth="800" d:DesignHeight="450"
x:Class="AlwaysOnTop.Views.MainWindow"
Topmost="True"
Title="AlwaysOnTop">
</Window>
