C# gains extension indexers and built-in union type support with System.Text.Json serialization. ASP.NET Core adds async validation for Minimal APIs, automatic CSRF protection via browser headers, Blazor Virtualize scroll-to-item, OpenAPI 3.2 by default, a new [ShortCircuit] attribute, and SignalR authentication refresh. .NET MAUI brings CollectionView to Windows via WinUI's ItemsRepeater, drops the Compatibility package, and adds Native AOT-safe HybridWebView interop. Entity Framework Core adds FULL OUTER JOIN translation, complex-type property key traversal, and SQLite encryption via SQLite3 Multiple Ciphers. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What does the new [ShortCircuit] attribute do in ASP.NET Core .NET 11? The [ShortCircuit] attribute lets an endpoint run immediately after routing, bypassing the rest of the middleware pipeline. It works with Minimal APIs, MVC controllers, and SignalR hub methods, and is useful for lightweight endpoints like health checks or robots.txt responses that don't need the full request pipeline. _daily.dev surfaces framework updates like this for teams optimizing ASP.NET Core request pipelines._ ### Does ASP.NET Core in .NET 11 automatically protect against CSRF attacks without configuration? Yes, applications built with WebApplication.CreateBuilder automatically reject unsafe cross-origin requests using the browser's Sec-Fetch-Site and Origin headers, with no configuration required. This protection works across Minimal APIs, MVC, Razor Pages, and Blazor, and Blazor Web App projects no longer need to call app.UseAntiforgery(). _Developers upgrading ASP.NET Core apps track security defaults like this on daily.dev._ ### Is Microsoft.Maui.Controls.Compatibility still shipped in .NET 11? No, the Microsoft.Maui.Controls.Compatibility package is no longer built or shipped in .NET 11 Preview 6, which is a breaking change for any project that references it directly. This coincides with Android Shell being re-implemented on standard MAUI handlers instead of legacy renderer classes. _Teams planning a MAUI upgrade watch for breaking changes like this via daily.dev._ ## Similar posts on daily.dev - [Microsoft Releases .NET 11 Preview 3 with Updates Across Runtime, SDK, MAUI, and ASP.NET Core](https://daily.dev/posts/microsoft-releases-net-11-preview-3-with-updates-across-runtime-sdk-maui-and-asp-net-core-4tyjhbtqm) · InfoQ · 5 upvotes · 1 comments - [.NET 11 Preview 3 is now available\!](https://daily.dev/posts/net-11-preview-3-is-now-available--lmnwr3zsd) · .NET Blog · 52 upvotes · 2 comments - [Microsoft unveils first preview of .NET 11](https://daily.dev/posts/microsoft-unveils-first-preview-of-net-11-4y7l7j8r0) · InfoWorld · 24 upvotes · 1 comments --- Tags: [#.net](https://daily.dev/tags/.net), [#c#](https://daily.dev/tags/c#), [#aspnetcore](https://daily.dev/tags/aspnetcore), [#.net-maui](https://daily.dev/tags/.net-maui) [View this post on daily.dev](https://daily.dev/posts/microsoft-releases-net-11-preview-6-with-language-and-framework-updates-oqwjdzv3l) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Microsoft Releases .NET 11 Preview 6 With Language and Framework Updates","url":"https://daily.dev/posts/microsoft-releases-net-11-preview-6-with-language-and-framework-updates-oqwjdzv3l","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/microsoft-releases-net-11-preview-6-with-language-and-framework-updates-oqwjdzv3l"},"datePublished":"2026-07-27T15:29:07.565Z","dateModified":"2026-09-14T06:02:12.197Z","description":".NET 11 Preview 6 has been released with updates spanning C#, ASP.NET Core, .NET MAUI, and Entity Framework Core.
