Overview of this book

In today’s software development landscape, efficient memory management is crucial for ensuring application performance and scalability. Effective .NET Memory Management addresses this need by explaining the intricacies of memory utilization within .NET Core apps, from fundamental concepts to advanced optimization techniques. Starting with an overview of memory management basics, you’ll quickly go through .NET’s garbage collection system. You’ll grasp the mechanics of memory allocation and gain insights into the distinctions between stack and heap memory and the nuances of value types and reference types. Building on this foundation, this book will help you apply practical strategies to address real-world app demands, spanning profiling memory usage, spotting memory leaks, and diagnosing performance bottlenecks, through clear explanations and hands-on examples. This book goes beyond theory, detailing actionable techniques to optimize data structures, minimize memory fragmentation, and streamline memory access in scenarios involving multithreading and asynchronous programming for creating responsive and resource-efficient apps that can scale without sacrificing performance. By the end of this book, you’ll have gained the knowledge to write clean, efficient code that maximizes memory usage and boosts app performance.

Chapter 9: Final Thoughts

Working with unsafe code

The unsafe keyword denotes a section of code that is not managed by the Common Language Runtime (CLR) or by unmanaged code. Unsafe is used to declare a type or member or specify a block code. When used to qualify a method, the context of the entire method is unsafe.

We will mention managed and unmanaged code several times while discussing low-level programming and unsafe code. As a reminder, managed code executes under the supervision of the CLR and the Garbage Collector (GC). They perform housekeeping tasks such as the following:

  • Managing memory for objects
  • Performing type verification
  • Doing garbage collection

Managed code in .NET is generally considered verifiably safe code, meaning that the .NET development tools can verify that the code is safe. The primary attribute of safe code is that it doesn’t directly access memory using pointers, allocate raw memory, or create managed objects.

On the other hand, unmanaged code...
