What you'll learn

Modern .NET applications increasingly require a deep understanding of memory behavior to avoid hidden allocations, GC pressure, lifetime bugs, and performance bottlenecks. In this course, Advanced C# 14: Systems and Memory, you’ll gain the ability to reason about memory placement, ownership, and lifetime in modern C# applications. First, you’ll explore stack and heap allocation, including Span, stackalloc, and ref struct, to understand how lifetime boundaries are enforced. Next, you’ll discover how native interop, unsafe code, and struct semantics affect memory correctness and performance. Finally, you’ll learn how to design async APIs using Memory, IMemoryOwner, and ArrayPool to safely manage memory across asynchronous boundaries. When you’re finished with this course, you’ll have the skills and knowledge of systems-level memory behavior in C# needed to design safer, more predictable, and more efficient .NET applications.
