    What’s New in ASP.NET Core 10 for .NET 10: Key Features and Enhancements

    ASP.NET Core 10 introduces significant improvements across Blazor, Minimal APIs, and OpenAPI. Blazor gains automatic asset fingerprinting, reconnection UI with state persistence via the [PersistentState] attribute, and enhanced JavaScript interop with async methods and cancellation token support. Minimal APIs now include built-in validation using DataAnnotations, Server-Sent Events support for real-time streaming, and improved form binding that maps empty strings to null for nullable types. OpenAPI 3.1 compliance brings YAML support, XML comment integration, and refined schema handling. Performance enhancements include new metrics for Blazor circuits, WebAssembly profiling tools, and faster startup times through preloaded assets.
