Drag and drop run through feedback

[crutkas]

Running through each feature individually, here was my feedback on drag and drop

drag and drop service

• lacks WTS todo
• in DropStorageItemsAction, can't seem to touch UI thread.
• code example for storing uses verb "Get" which is odd. DropStorageItemsAction="{x:Bind GetStorageItems}"
• why doesn't the service resolve in xaml, had to manually add the namespace?
• any error in the page, compiler throws error that all methods aren't methods. "Severity Code Description Project File Line Suppression State Error XLS0525 'DragItemStarting' is not a method. App6 BlankPage.xaml 23
• documentation I think should reference the primary use cases then anchor link to that use case.
• documentation inside that use case should have end to end. I was doing a drag and drop example and had to go up to nab the namespace.
• documentation was a bit unclear what had to be added where (was using code behind)
