Here is my latest work on WP7.
Started a couple of hours ago and just finished designing.

Note: Used AAA Logo Creator's Symbols for that


You can use it for General Purpose Design as well as ApplicationBarIcons.Here is the Download Link: Download the IconSet


And here is a sheet showing you the IconSet.

Its fully supported for Light and Dark theme.

Here are the common properties for each icon in the set:

Canvas Size : 48 X 48
Image Size : 36 X 36
Location X : 6
Location Y : 6

I've also tested it myself before releasing:


Dark Theme




Light Theme




Hope it helps,

Have a nice day!
