Parse versus TryParse
The lesson introduces the TryParse pattern as the preferred alternative to Parse methods, explaining how TryParse avoids generating exceptions internally and returns a boolean plus an out-parameter result. We cover common framework inconsistencies where some APIs still throw for non-critical conditions, and the design principle of avoiding exceptions in tight loops.
