Worked for a Medical Transportation company that had a contract with Medicaid.
One of their many rules was that you could not provide any assistance to the patient INSIDE of their house.
One elderly lady had an old house with a very small foyer that you had to climb three steps to get to the main floor. The only other entrance was around back and up two and a half flights of rickety steps to an old deck that opened into a bedroom.
Upstairs. She's in a wheelchair.
Common sense says take her in the front door, up three stairs and she's home on the level she lives on.

"You want to associate the changes to the file to a work item, not the file itself." Most of the time yes, but not all the time. You may want to link a workitem to a code file to remember to research it later, or to record what looks like a bug but you may not have time to look into it during the current task. The code review is close but is still linking to a shelfset. — StingyJack1 min ago
"That code is a weird mix of C++ and pointlessly-low-level/opaque code." There is an important lesson in there, @RakeshKarandikar . Online judges rarely reward for code that passes a code review, but good code is what get you hired and keeps you hired. Learn what you can from competition sites, but also read up on and practice good software engineering. — user45813019 secs ago

ThrowEvent is odd terminology, usually you'd call it RaiseEvent. Your getNewID method is not thread safe, you may end up reusing an Id. Try the Interlocked class to get around that. I highly recommend looking into c# naming conventions. As you mention Unity, I know they may differ there, but double underscores is very odd (and hard on the eyes), most especially when used for local variables and parameters. At the very least be consistent. Also, as you have "a working solution", this question is probably a better fit for codereview.stackexchange. — pinkfloydx3344 secs ago
