if you set TargetFramework to net6.0-windows and UseWPF to true in your *csproj:

<TargetFramework>net6.0-windows</TargetFramework>
<UseWPF>true</UseWPF>

<TargetFramework>net6.0-windows</TargetFramework>
<UseWPF>true</UseWPF>

you can use

using System.Windows;

MessageBox.Show("text", "caption", MessageBoxButton.OK, MessageBoxImage.Question);

using System.Windows;

MessageBox.Show("text", "caption", MessageBoxButton.OK, MessageBoxImage.Question);

there are a couple of options for MessageBoxImage (and MessageBoxButton)
