I am using [Material Design in XAML](http://materialdesigninxaml.net/) to style my WPF UI controls. I defined the default theme in the App.xaml file.

```xaml
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                    <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
                    <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
                    <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.DeepPurple.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml" />
            </ResourceDictionary.MergedDictionaries>            
        </ResourceDictionary>
    </Application.Resources>

```

However, I want some of my controls to have the default WPF look and feel, but it looks like the Material Design in XAML overrides the WPF default control style.

Example: The button below automatically takes its style from the Material design without specifying it.

```xaml
<Button Content="Hello" Width="100"/>

```

How can I disable the Material Design in some controls?
