.NET 11 Preview 5 has been released, enhancing runtime, SDK, libraries, ASP.NET Core, .NET MAUI, and Entity Framework Core. Notable updates include support for JSON Lines serialization and improved JIT optimizations.
Microsoft has released the fifth preview of .NET 11, introducing various enhancements across multiple components. This preview is critical for developers using .NET technologies and aims to refine the efficiency and capabilities of existing tools.
Key updates in the libraries include the addition of JSON Lines serialization support in System.Text.Json and full outer joins in LINQ. The cryptography library now offers X25519 key agreement, and the Random class gains new generic numeric APIs. These changes enhance functionality and usability for developers.
The .NET runtime has undergone optimizations, improving async suspension and JIT performance. Additionally, the SDK has been updated to allow file-based applications to reference other C# files, thereby streamlining the build process. This update also includes vulnerability checks during build, enhancing security for developers.
ASP.NET Core sees improvements in Blazor Server-Side rendering and support features for QuickGrid without interactivity. Meanwhile, .NET MAUI has introduced reliability updates, including API stabilization for .NET for Android and enhancements in animation handling.
In Entity Framework Core, the default is now set to SQL Server 2022 compatibility, and the CLI tool dotnet ef adds support for file-based applications. Additionally, the framework warns developers when asynchronous EF queries run synchronously, helping to avoid performance pitfalls.
