About this course

Writing functional C# code is only the first step; writing code that manages memory efficiently prevents server crashes and high hosting costs. Even small, unnoticed coding habits can lead to massive memory bloat and performance bottlenecks in production. This course guides you through the inner workings of .NET memory management, giving you the knowledge to write highly optimized applications. You will transition from writing basic C# to crafting efficient, high-performance code that plays nicely with the garbage collector. What you'll learn: - Understand the fundamental mechanics of the .NET Garbage Collector and memory generations. - Identify and resolve common memory allocation issues like unexpected boxing and collection resizing. - Apply modern C# features like Span and Memory to minimize heap allocations. - Optimize string manipulation and prevent unnecessary string duplication. - Implement efficient resource cleanup patterns using the disposable pattern. - Analyze and debug memory usage to spot memory leaks before they reach production. The course starts with foundational memory concepts and garbage collection basics before moving into practical code optimization patterns, memory-saving structures, and modern performance techniques. This course is designed for C# developers who understand basic syntax and want to write more efficient, professional-grade software. No advanced systems programming experience is required. Start writing faster, leaner, and more reliable C# applications today.

Found it useful for a refresher. Not sure it would be the best starting point for a complete beginner, tbh.

Pretty good overall. The structure was logical, and many of the examples were helpful. A few areas could have used a bit more depth, but it's solid.
