Atomic here means the data operation is performed by a single assembler instruction,

add dword ptr[esp+0x20], eax
inc dword ptr[edi]
; other r-m-w instructions

so if two ints need to represent a consistent state, then you also would need a lock

Don't ever use the Convert class

Because it's needless, nearly all its methods simply wrap other methods (e.g. Int32.Parse). It offers no benefit and adds an extra method call.

It's more a matter of style, discipline, and clarity of thought.

All of which do matter if you want to produce a quality product.
