Quick Strategies to Reduce Memory Usage in .NET Avoid Memory Leaks: Unsubscribe from events, avoid static references.Use Span&lt;T&gt; / Memory&lt;T&gt;: Efficient buffer handling without allocations.Use ArrayPool&lt;T&gt; / ObjectPool&lt;T&gt;: 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.
