EF Core, indexing, and Copilot updates
This issue covers .NET 9 and 10 features, async APIs, caching, EF Core tuning, SQL Server indexing, Dapper, and Visual Studio Copilot diagnostics.
Jasen's top three picks
- 1 What’s New in .NET 9: Exploring C# 12 Features and Serverless Performance
medium.com
A good .NET 9 refresher with some real performance context, not just feature-tour fluff.
- 2 Building a Fast .NET Core API with Async Programming
medium.com
Async, caching, and ArrayPool all land in the same efficiency zone here.
- 3 Efficient Caching Strategies: Write-Through vs. Write-Behind Caching

Several database posts make the same point from different angles: query shape matters more than framework loyalty.
Editor's note
I curated a pretty practical mix this time: performance, data access, and debugging dominate the lineup, with a few architecture pieces mixed in. The Copilot diagnostics toolset in Visual Studio stands out for making day-to-day troubleshooting faster, while the SQL Server indexing and EF Core posts are solid reads for anyone chasing query latency.
