The .NET 10 Preview 1 isn’t the final product—it’s more like a try-before-you-buy version that’s inviting developers to jump in, experiment, and share feedback. Here are some of the standout features that Microsoft is excited about:

• Performance boosts: Expect a faster and leaner runtime. The preview comes with improvements that aim to slingshot application performance, making heavy lifting feel a lot breezier.
