What types of memory management issues can occur in applications and how can they be identified?

The following memory management issues can occur in C# applications:

• Memory leaks — objects remain in memory even though they are no longer used, due to references that were not nullified.
• Hangs caused by the garbage collector (GC) — frequent or long pauses during garbage collection can affect performance.
• High memory consumption — due to inefficient use of objects or storing large data.

To identify problems, use:

• Memory profilers (e.g., built-in in Visual Studio or third-party tools), which show object distribution and their lifecycle.
• Memory dump analysis — helps find objects that are not released.
• Logging and monitoring memory usage during application runtime.

It is important to ensure proper resource release, use using constructs for objects implementing IDisposable, and avoid strong references to objects that should be collected by the garbage collector.
