Price covering highlights of .NET 10 and C# 14. Key topics include the new extension members syntax (extension blocks for properties, methods, and constructors), null conditional assignment on the left-hand side, file-based apps (running a single .cs file without a project file), and the extended STS support lifecycle now at 24 months. ASP.NET Core 10 improvements are also discussed, including automatic model validation for minimal APIs and auto-generated public partial class Program for integration testing. The conversation also covers Aspire 13's rebranding as a polyglot orchestration tool supporting JavaScript and Python, .NET MAUI's Linux desktop support via Avalonia, and the importance of keeping runtimes updated monthly. ## Full article daily.dev links to this article rather than hosting it.
