Customizing WindowButtonCommands styles in Mahapps.Metro

Question

I want to change the style of the Min, Max, and Close buttons for my WPF application.

I use Mahapps.Metro , and I managed to achieve the result that I want, but only with outdated WindowMinButtonStyle WindowMaxButtonStyleand WindowCloseButtonStylein class MetroWindow. An outdated message, such as a property WindowMinButtonStyle, reads:

This property will be removed in a future version. You must use LightMinButtonStyle or DarkMinButtonStyle in WindowButtonCommands to override the style.

The problem is that I cannot figure out how to do this specifically. The class MetroWindowhas a field called WindowButtonCommands, but it is internal, therefore, it seems that it is the wrong tree to bark up. I am new to WPF and there is no information on how to do this in the manuals on their website, so I'm pretty lost. I hope someone can provide me with a short code example to point me in the right direction.

EDIT . Here XAML issues a warning:

<controls:MetroWindow x:Class="Project.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:controls="http://metro.mahapps.com/winfx/xaml/controls"
        WindowMinButtonStyle="{DynamicResource DarkWindowButtonStyle}"
        WindowMaxButtonStyle="{DynamicResource DarkWindowButtonStyle}"
        WindowCloseButtonStyle="{DynamicResource DarkWindowCloseButtonStyle}">
    <Grid>
    </Grid>
</controls:MetroWindow>

I should also mention that I am using the new v1.2.0 from Mahapps.Metro, but I had the same problem with the previous version. Source code of Mahapps.Metro, which has attributes Obsolete: https://github.com/MahApps/MahApps.Metro/blob/develop/MahApps.Metro/Controls/MetroWindow.cs#L88-L93
