Value Tracking

ReSharper | Inspect | Value Origin/Destination

Value Tracking helps you investigate value of a particular type and possibly determine how a certain incorrect value might have passed to a given point in your program, and where it might be passed next. This helps you investigate possible NullReferenceException, inappropriate behavior, and reasons why you get incorrect values.
