#修正
Brushの定義の所でDynamicResourceにしてたら例外出たので全部、StaticResourceにしました。
テーマ変更したい時があったので、Brushも対応するよう変更しました。
#最初に
この記事は、Material Design In XAML Toolkit がインストールされている前提になります。
もし、インストールしていない場合は、プロジェクトを右クリックして、Nuget パッケージの管理から MaterialDesignThemes をインストールしてください。
説明

MaterialDesignThemeを使ってると、「あ、ここのボタンFlatにしたいな」って時に
{StaticResource MaterialDesignFlatButton} とか手入力しないといけない。
そう、面倒くさい...。
面倒くさいということは、改善の余地があるということで。以下、MaterialDesignThemeのスタイルをほぼほぼ定義してみました。
下記のスタイル定義は、以下のリンク先からさらってきました。チュートリアルとかもあるので、使ったことが無い方は一読しておくと良いと思います。

#MaterialDesignTheme のスタイル定義
基本的には要素ごとにまとめて、後はその要素に関わりのあるものも一緒にしてまとめてあります。（ScrollBarならRepeatButtonとかもScrollBarのところに宣言してある）
カラー名は一部変更してます。
[追記] スタイル名も変更しました。
多分、これ必要？みたいなのもあると思いますが、問題があるようなら適宜削除して下さい。
