About this course

Writing code that works is only the first step; writing code that performs well is what distinguishes a professional developer. This course addresses the common pitfalls that slow down C# applications and provides the technical foundation needed to write highly responsive software. You will transition from writing basic functional code to crafting optimized solutions that scale. By understanding how the runtime handles your instructions, you will learn to make informed decisions about data structures, memory usage, and execution flow. What you'll learn: - Understand foundational memory management and how the Garbage Collector impacts speed - Apply efficient string manipulation and collection patterns to reduce overhead - Analyze Common Intermediate Language (CIL) to understand how the compiler interprets your code - Practice benchmarking techniques to accurately measure and compare code performance - Implement modern optimization features such as Span<T> and Memory<T> for efficient memory usage - Optimize exception handling and control flow to prevent unnecessary execution delays The course begins with essential terminology and the mechanics of the execution environment before moving into practical coding scenarios and performance analysis. It is designed for beginner developers who want to deepen their technical expertise; no prior optimization experience is required. Start building faster C# applications by mastering professional performance techniques today.
