Microsoft has released ASP.NET Core 11, introducing a range of new features and improvements aimed at enhancing the developer experience across Blazor, OpenAPI, and general web development workflows. ASP.NET Core is shipping some of the most impactful improvements we've seen in a while. Whether you're building APIs, real-time apps, or distributed systems with Aspire, there's something here that'll make your life easier. HTTP/3 has been in preview for a while, but .NET 11 ships a meaningful improvement: the server starts processing requests earlier in the connection lifecycle. Among the most notable additions is the new EnvironmentBoundary component for Blazor, which allows developers to conditionally render content based on the hosting environment. The component accepts Include and Exclude parameters and works consistently across both Blazor Server and Blazor WebAssembly, removing, as explained, the need for manual environment checks.
