I am not much familiar with documenting/System designing stuff.I have to maintain an application written in C# - working as windows service.However there is no documentation for this system which makes it really pathetic to find where some problem (conceptually) occurred.I would like to know the best way to design/document it (using current code) manually or preferably automatically so that I can identify the exact problems.Like I feel as if sequence diagram won't much help probably.Also, please guide me if I am taking it on wrong side?
