How to Prevent Memory Leaks in C#

Unsubscribe from Events: Always remove event handlers when done to prevent unwanted references.
Dispose Unmanaged Resources: Use IDisposable and using blocks for objects like files, streams, and DB connections.
Avoid Static References: Static variables can keep objects alive, clear them when no longer needed.
Manage Caching Properly: Use cache expiration and clear caches periodically.
Follow Proper Dispose Patterns: Implement Dispose and suppress finalizers when needed.
Handle GUI Resources Carefully: In WPF/WinForms, remove unused bindings and UI elements.
Prefer Value Types When Appropriate: Value types are GC-friendly compared to reference types.

The most likely cause of memory leaks is unmanaged code (resources). If you can be specific about how you know you have memory leaks and what unmanaged code you are using then that will help us help you.
