Explore techniques for improving C# code performance by reducing memory allocations in this one-hour conference talk. Learn about using structs efficiently, understand the differences between classes and structs, and discover the benefits of the Span runtime type for working with memory slices. Examine recent C# features that enable allocation-free coding, including ref returns, readonly structs, and ref structs. Dive into practical examples using System.Text.Json and micro-benchmarks to measure performance improvements. Gain insights on when to apply these techniques and when to avoid them, ensuring optimal code performance without sacrificing readability or maintainability.
