Value Types vs Reference Types in C# #Shorts

Why does changing one variable sometimes change another one too? It comes down to whether you're holding a value type or a reference type. This Short breaks down how C# copies value types (int, struct) directly while reference types (class, array) share a single object on the heap — plus the classic aliasing bug that catches people off guard, and a simple rule of thumb for choosing struct vs class. Zero to Pro is a series of short, focused explainers on the C# and .NET concepts that trip developers up. New one dropping regularly — subscribe to keep leveling up.
