Time, async, AI prompts, and .NET 10 Preview 6
A varied .NET roundup covering date/time handling, async pitfalls, AI prompting, ASP.NET Core minimal APIs, Copilot tips, and .NET 10 Preview 6.
Jasen's top three picks
- 1 DateTime and TimeSpan in C#: Handling Dates Without Headaches
Medium
A useful refresher on DateTime and TimeSpan basics for anyone who still gets tripped up by time math.
- 2 How Prompt Engineering Changed the Way I Write Code
C# Corner

- 3 Difference Between Task, async/await, and Threading in .NET
C# Corner
Task, async/await, and Threading are not interchangeable, so it’s worth revisiting the boundaries before the next performance bug.
Editor's note
I pulled together another deliberately mixed issue: practical C# time handling, async/await pitfalls, and a solid look at .NET 10 Preview 6. I also liked the Copilot Chat prompts piece because it’s the kind of workflow article that can save real time right away, not just theory.
