C# Memory Management: Using Span and Memory for Zero-Allocation

Introduction: The Cost of the Garbage Collector (GC) One of the biggest advantages of modern .NET development is managed memory. Developers do not need to concern about manual memory allocation and deallocation like in C or C++. The .NET Garbage Collector (GC) get that concern on behalf of programmers, it automatically handles memory cleanup, making development safer and more productive. Here is the master class of C# memory management However, “managed code” does not mean free performance. When applications allocate too many objects on the heap, the Garbage Collector must frequently run to get back memory. This is the reason for several performance challenges: GC Pressure – Frequent object allocations increase the workload for the garbage collector. Stop-the-world pauses – The GC temporarily pauses application threads to get back memory. Heap fragmentation – Repeated allocations and deallocations create ineffective memory layouts. In most enterprise applications, this overhead is acce
