How do I see the App Bar in design mode while using Blend for Visual Studio 2012 RC?
By default for Split App, you have to uncomment the AppBar that is commented out by default.
Change this:
<!-- <div id="appbar" data-win-control="WinJS.UI.AppBar">
<button data-win-control="WinJS.UI.AppBarCommand" data-win-options="{id:'cmd', label:'Command', icon:'placeholder'}"></button>
</div> -->
to this:
<div id="appbar" data-win-control="WinJS.UI.AppBar">
<button data-win-control="WinJS.UI.AppBarCommand" data-win-options="{id:'cmd', label:'Command', icon:'placeholder'}"></button>
</div>
Then right-click on the appbar
in the Live DOM pane and select Activate AppBar.
Kudos goes to Matt Hidinger for sharing this helpful tip.
