.NET 11 Preview 5 introduces significant updates, including improved garbage collection, full outer joins in LINQ, and enhanced JSON Lines serialization for large data streams. Developers will benefit from reduced boilerplate code and memory fragmentation, as well as automatic vulnerability checks during the build process. The SDK now allows for direct references between C# files and includes new templates to streamline project setup and reduce the need for common workarounds. Overall, this preview focuses on practical performance improvements and cleaner query paths, aiming to enhance developer experience and application reliability

.NET 11 Preview 5 Delivers Faster GC, LINQ Joins, and Cleaner Queries for Developers

.NET 11 Preview 5 drops a batch of runtime and library updates that actually cut down on boilerplate and memory fragmentation. Developers will notice the new full outer joins in LINQ and JSON Lines serialization finally handling large data streams without custom parsers. The garbage collector gets tighter compaction rules while the SDK runs automatic vulnerability checks during the build process to stop dead dependencies from shipping. Blazor server-side rendering and Entity Framework Core both ship cleaner query paths that prevent the kind of silent performance tax that usually blindsides production deployments.
