  JWT authentication in ASP.NET Core is a stateless, token-based approach where clients send a signed JWT (usually as a bearer token) and ASP.NET Core validates it on every request to build HttpContext.User. It’s for developers building APIs (REST, SPAs, mobile back ends, microservices) who want scalable authentication without server sessions. The key is understanding how tokens are structured, how they’re validated in the middleware pipeline, and how to handle lifetimes and refresh securely. ( IETF Datatracker ) Why does JWT authentication matter for modern APIs? Modern APIs are consumed by SPAs, mobile apps, partner services, and internal microservices, often across domains and deployments where cookie-based sessions are awkward or undesirable. JWTs are popular because the server can validate a request using only the token and its signing key (or issuer metadata) without loading per-user session state from a shared store. That “statelessness” improves horizontal scalability, but ...

  EF Core vs. Dapper: What should you use Use EF Core when you want a full ORM that boosts productivity and long-term maintainability (LINQ, change tracking, migrations, cross-database providers). Use Dapper when you want maximum SQL control and minimal overhead, especially for read-heavy or performance-critical endpoints. If you’re building a large system, a hybrid approach (using EF Core for writes and Dapper for reads) often provides the best balance. How do you choose between EF Core and Dapper in 60 seconds Choose EF Core if most of these are true: You’re building CRUD-heavy business features. You want LINQ and strongly typed query composition. You benefit from change tracking and unit-of-work patterns. You want migrations and schema evolution built in ( Microsoft Learn ). You want easy provider switching across databases ( Microsoft Learn ). Choose Dapper if most of these are true: You need handwritten SQL for complex joins, common table expressions (CTEs), or reporting. You’...
