What’s New in C#: Modern C# in 2026

C# continues to evolve, adding new features that make code more expressive, concise, and easier to maintain. But with so many additions to the language, which ones should you actually care about?
In this session, we’ll take a practical tour of what’s new in modern C#, exploring the latest language features and how they can improve the way you write .NET applications. We’ll look at new syntax, improvements to the type system, pattern matching, constructors, collections, and other features designed to reduce boilerplate and make everyday development easier.
Rather than simply reviewing a list of features, we’ll use real code examples to see where these capabilities fit, when they’re useful, and how they compare with the C# you’re already writing.
Whether you’ve been writing C# for years or are getting back up to speed with the latest versions, this session will help you understand how modern C# is changing—and which features are worth adding to your toolbox.
