EF Core, webhooks, and .NET MAUI billing
A varied .NET roundup on reliability, performance, security, MAUI billing, Git workflows, and practical C# patterns for everyday teams.
Jasen's top three picks
- 1 Building Reliable Webhooks in ASP.NET Core
Medium
Solid practical webhook advice: validation, retries, and idempotency are the difference between “works” and “survives production.”
- 2 In-Memory Caching in .NET (IMemoryCache)
Medium
Caching and LINQ pitfalls are the kind of day-to-day topics that save teams from expensive surprises later.
- 3 5 LINQ Mistakes That Pass Code Review But Crash Production
Medium
The EF Core optimization posts are the performance section’s highlights—one aims for speedups, the other shows how to avoid unnecessary query work.
Editor's note
I curated a pretty mixed issue today: reliability, performance, architecture, and tooling all show up. I’d call out the webhook piece for its real-world idempotency guidance and the EF Core performance challenge for anyone chasing measurable wins. The MAUI billing sample is also timely for mobile teams shipping cross-platform monetization.
