✨ New features in .NET 9

The software development kit (SDK) supports using the latest C# (C# 13) and F# (F# 9) versions.
The SDK now uses the new terminal logger by default, which improves the usability of the .NET command-line interface.
The base library, garbage collection (GC), and just-in-time (JIT) have seen many performance improvements. The GC now defaults to the dynamic adaption to application sizes (DATAS) mode, which resizes the heap based on the active workload.
.NET 9 has many API additions that improve performance, like overloads using the new C# 13 params Span and allowing C# 13 generic ref struct parameters to eliminate allocations. .NET 9 also includes many enhancements to its JSON support. For interoperability and efficient operations on AI data, .NET provides a new Tensor<T> type
ASP.NET Core 9 comes with built-in support for OpenAPI document generation. Additionally, the new MapStaticAssets middleware provides optimized support for delivering static assets.

Whether you’re working on enterprise applications, AI projects, or cutting-edge web services, .NET 9.0 brings powerful tools to developers.
