Creating Minimal Web APIs with .NET Online Course

Creating Minimal Web APIs with .NET Online Course

This course introduces you to Minimal APIs in ASP.NET Core, designed for building lightweight HTTP APIs ideal for microservices. You’ll learn the differences between Minimal and MVC APIs, work with Entity Framework, Dependency Injection, DTOs, AutoMapper, and exception handling, and implement key endpoints like GET, PUT, and DELETE. By the end, you’ll be confident in creating RESTful Minimal APIs using .NET Core for real-world projects.

Who should take this course?

This course is ideal for .NET developers, backend engineers, and software professionals who want to learn how to build lightweight, high-performance APIs with minimal configurations. It’s also great for beginners in .NET who want hands-on experience in modern API development.
