It is normal practice for developers to include "TODO" comments for fellow developers and themselves. Developers also spend a lot of time searching for them later.
In Visual Studio (VS), a quick way to retrieve a list of all the TODO's in a project is to go to View → Other Windows → Task List. Visual Studio will display the Task List pane. Make sure the dropdown list at the top of the pane reads "Comments," and VS will display a list of all the TODO comments in the project.
