Todo tasks not appearing in the Task List in visual studio 2012
Actually there is a dropdown control at the top of the "Task List" window and if you use the Visual Studio 2012 Dark Theme the dropdown looks like a label. If you click the "User Tasks" text, you will see "Comments" selection which lists your comments that contain "//todo".
