    Define a CustomControl like this

    in .cs

    public class MyButton : Button
    {
        static MyButton()
        {
           //set DefaultStyleKeyProperty
        }   
    
        public ImageSource ImageSource
        {
            get { return (ImageSource)GetValue(ImageSourceProperty); }
            set { SetValue(ImageSourceProperty, value); }
        }
    
        // Using a DependencyProperty as the backing store for ImageSource.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty ImageSourceProperty =
            DependencyProperty.Register("ImageSource", typeof(ImageSource), typeof(MyButton), new UIPropertyMetadata(null));
    }
    

    in generic.xaml of themes folder

    <Style TargetType="{x:Type MyButton}">
        <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type MyButton}">
                <StackPanel Height="Auto" Orientation="Horizontal">
                    <Image Source="{TemplateBinding ImageSource}" Width="24" Height="24" Stretch="Fill"/>
                    <TextBlock Text="{TemplateBinding Content}" HorizontalAlignment="Left" Foreground="{DynamicResource TaskButtonTextBrush}" FontWeight="Bold"  Margin="5,0,0,0" VerticalAlignment="Center" FontSize="12" />
                </StackPanel>
            </ControlTemplate>
        </Setter.Value>
        </Setter>
    </Style>
