JWT claims, LINQ, EF Core and more
A mixed .NET lineup covering authorization, query translation, EF Core tuning, SignalR, NuGet sponsorship, Azure Functions, and AI agent architecture.
Jasen's top three picks
- 1 Using Custom JWT Claims for Authorization in .NET
medium.com
Custom JWT claims are a reminder that authorization usually lives in your app, not just in the token.
- 2 How LINQ Turns Your C# Code into SQL Queries (With Real Examples)
c-sharpcorner.com
LINQ-to-SQL explanations are always worth a look when teams need to understand what EF Core is really sending to the database.
- 3 🧩 Building Microservices with C# and .NET Core — A Complete Guide with Example
c-sharpcorner.com
The EF Core pagination and N+1 posts pair nicely if you’re tuning data access for scale.
Editor's note
I curated a broad mix again this time: practical data-access pieces, platform updates, and a few architecture topics. The NuGet.org Sponsorship announcement stands out for package maintainers, and the EF Core pagination and N+1 articles are useful if you’re chasing real-world performance.
