Explore the new features and improvements introduced in the C# 14 language specification. Articles in this category provide in-depth coverage of syntax changes, feature expansions, and clarifications to language rules – offering a clear understanding of how these incremental improvements impact code reliability, readability, and maintainability in modern .NET development.
C# 14 introduces a new capability to declare instance constructors and events as partial members. This means you can split a constructor or event definition across two parts of a partial class, similar to how C# has long allowed partial methods and (since C# 13) partial properties. In simpler terms, one part of a partial…
C# 14 introduces several small but helpful improvements to the language. One of these new features is an enhancement to the nameof expression – it now supports unbound generic types. In simple terms, you no longer need to plug in a placeholder type argument just to get the name of a generic type. This update…
C# 14 introduces a significant enhancement for high-performance code: first-class language support for spans. In particular, it adds new implicit conversions between Span<T>, ReadOnlySpan<T>, and arrays (T[]). This change makes it much easier to work with these types that represent safe, contiguous memory slices without extra allocations. In this article, we’ll explore what span conversions…
C# 14 introduces a new contextual keyword, field, that can be used inside a property’s accessors (the get, set, or init blocks) to refer to the property’s backing storage. In simpler terms, field is a placeholder representing the hidden variable where a property’s value is stored. This keyword lets you add custom logic to automatically…
C# 14.0 will be released later this year, in November, at the same time as .NET 10. See here what’s new in the .NET 10 runtime, including performance benchmarks. There are several new features and improvements in C# 14: C# 14.0 is currently in preview:
