Failure to implement proper exception handling can lead to unpredictable runtime errors. Developers should surround potential error-prone code with try-catch blocks to gracefully handle exceptions and prevent abrupt program termination.

2# Memory Management Issues:

Improper memory management, such as failing to release resources with the using statement for disposable objects or neglecting to handle circular references, may result in memory leaks and degrade application performance.

3# Overlooking Null References:
