EF Core, Endpoint Filters, Memory Safety
EF Core migrations best practices, ASP.NET Core endpoint filters, FluentValidation in .NET 10, rate limiting strategies, and C# 15 union types.
Jasen's top three picks
- 1 EF Core without migrations - it's only a matter of time
Round The Code
Migrations aren't optional—they're how you keep databases sane across dev, staging, and production.
- 2 ASP.NET Core Endpoint Filters: A Complete Developer Guide
C# Corner
Endpoint filters let you intercept and validate requests at the routing layer; cleaner than middleware for Minimal APIs.
- 3 FluentValidation in ASP.NET Core .NET 10 - Request Validation
codewithmukesh
FluentValidation 12 with endpoint filters is the modern way to validate in .NET 10.
Editor's note
This week’s mix spans data consistency, API request handling, and language evolution. The EF Core migrations piece and rate-limiting guide are production-focused deep dives that’ll save you headaches. Union types finally landing in C# 15 is a long-awaited feature worth understanding early.
