Microsoft has unveiled the sixth preview of its planned .NET 9, a major release of the company’s cross-platform software development framework that brings improvements in areas ranging from code layout to System.Numerics. With .NET 9, the ASP.NET web framework introduces fingerprinting of static web assets, which promises to improve caching behavior and enable faster load times.
