Windows Store Apps 的近況?
Microsoft by the Numbers

MetroStore Scanner

iOS 及 Android 平台上皆已超過 100 個萬個 Apps

但是…有 66% 是「僵屍」Apps:

Windows Store Apps 的下載率則超過9成 (聚光燈效應?藍海市場!?)

 Flyout 是一種輕量型 UI (或稱「飛出視窗」)。飛出視窗與
對話方塊不同，您只要按一下或點選視窗外的地方，就可
以輕鬆地將它關閉。
 您可以使用飛出視窗收集使用者輸入、顯示項目的詳細資
料，或是要求使用者確認動作。
 飛出視窗應該只在回應使用者點選或按一下的動作時顯
示，而且只要使用者在視窗外點選就會關閉。

所有的 Win8 Apps，都能直接在 Win8 及 Win8.1 機器的市集中下載並且順
利運行；然而 Win8.1 Apps ，則只能運行在 Win8.1 的機器上。

以這樣的角度看來，繼續開發 Win 8 App 以能同時在 Win8 及 Win8.1 的機
器上運行，就會是很明智的作法，以同時讓最多的使用者有機會下載使用。

不改Code的情況，Windows 8.1 apps 就是跑的比較

Visual Studio 2012 及Visual Studio 2013 可以同時安裝並執行
在同一台機器上! (使用 Visual Studio 2012 開發 Win8 App，或
是使用 Visual Studio 2013 開發 Win8.1 App)
