Override styles

you can override styles like this: first in your app.xaml add this:

 <Style x:Key="MessageBoxCustom" TargetType="hc:MessageBox" BasedOn="{StaticResource {x:Type hc:MessageBox}}">
        <Setter Property="NonClientAreaBackground" Value="#262e2f"/>
        <Setter Property="OtherButtonHoverBackground" Value="#888580"/>
        <Setter Property="OtherButtonForeground" Value="White"/>
        <Setter Property="OtherButtonHoverForeground" Value="White"/>
        <Setter Property="NonClientAreaForeground" Value="White"/>
        <Setter Property="CloseButtonForeground" Value="White"/>
 </Style>

now you must set this style in your messagebox:

MessageBox.Show(new MessageBoxInfo
            {
                Message = "Ask",
                Caption = "Title",
                Button = MessageBoxButton.YesNo,
                IconBrushKey = ResourceToken.AccentBrush,
                IconKey = ResourceToken.AskGeometry,
                StyleKey = "MessageBoxCustom"
            });

Customize Button Text

Only Available in Custom Version

MessageBox.Show(new MessageBoxInfo
            {
                Message = "Ask",
                Caption = "Title",
                ConfirmContent = "Ok"
            });
