Adding a comment such as this:
// TODO: Refactor this code
...creates a task in the Task List that I can view etc. There is a column labeled !
that lets you sort these tasks by priority.
How can I set a specific task's priority?
The priority of the task depends on the keyword you use to tag it. You can see and edit a list of keywords and their priorities by going to Tools->Options->Environment->Task List.
For example, on my installation, I've got HACK, TODO and UNDONE as normal priority, and UnresolvedMergeConflict as high priority.
If you want to add a new tag, type it into the "Name" box, choose a priority, and then click "Add".
