Quick Strategies to Reduce Memory Usage in .NET Avoid Memory Leaks: Unsubscribe from events, avoid static references. Use Span<T> / Memory<T> : Efficient buffer handling without allocations. Use ArrayPool<T> / ObjectPool<T> : Reuse buffers/objects to avoid heap pressure. Avoid Boxing: Use generics to prevent value type boxing. Avoid Unnecessary async/await: Use Task.FromResult for sync-like returns. Use StringBuilder / Interning: Efficient string handling and reuse. Stream Large Data: Avoid loading entire files/JSON into memory. Avoid ToList() on Large Queries: Use deferred execution ( foreach , yield ). Limit Large Object Heap (LOH): Keep large arrays under 85K if possible. Cache Smartly: Use size- and time-based eviction policies.
