Discover why structs as dictionary keys can cause hidden allocations in C#. Learn how to implement IEquatable, use readonly and record structs, and write allocation-free, high-performance code for hot paths.
If you’ve been coding in C# for a while, you’ve probably heard about boxing and unboxing. These concepts deal with how C# handles conversions between value types and reference types, and they can significantly impact your application’s performance. What’s the Difference Between Value and Reference Types? In C#, value types (like int, float, struct) live on the stack, while reference types (like string, object, classes) live on the heap. This distinction matters for performance and memory management. ...
