In this session, you'll learn to write C# code that executes faster and allocates less. This session is packed with practical examples and demos of where the latest high-performance APIs and language features can be applied. We'll apply types such as Span and Memory to efficiently process data and to parse strings. We'll examine System.IO.Pipelines, offering high-performance I/O and we'll utilise ArrayPool to reduce GC allocations. We'll discuss when and why performance matters and you'll learn how to measure your code, using a data-driven approach to focus your optimisations. These features can seem complicated, unapproachable and difficult to apply. In this session, Steve introduces high-performance newcomers to the features, showing you how they work, where they can be applied and how to measure performance improvements in your code. This talk is for developers, who like Steve, are ready to begin their journey towards writing faster .NET code, which allocates less.
