10.リソースの3通りの書き方③
戻るリソースディクショナリをApp.xamlに記述
画面を開くと、背景色がグリーンのボタンが表示されています。
開いた時
クリックすると拡大します
カーソルがボタンの上に来ると、背景色がオレンジ色に変わります。
これは、リソースの記述とそのリソースをボタンに指定したZAMLで実現しています。

下記がリソースをApp.xamlに記入している例です。
App

下記がViewのZAMLです。
ボタンでは、83行目で、Style="{StaticResource CommandTemplate}"とリソースのx:Key="CommandTemplate" のCommandTemplateをStyleとして指定しています。

ViewModelは下記の通りです。ボタンの背景色に関しては、何の記述もしません。
