Ultimate ASP.NET Core Web API Development Guide

Descripción

Learn to build scalable, secure, and professional-grade Web APIs with ASP.NET Core and C#. In this hands-on, step-by-step course, you’ll learn how to design, develop, and deploy modern RESTful APIs using ASP.NET Core, Entity Framework Core, and enterprise-ready best practices. Whether you’re an aspiring backend developer or an experienced engineer looking to sharpen your skills for .NET 9 / 10, this course will give you everything you need to create production-ready APIs confidently. What You’ll Learn • Master the fundamentals of RESTful API design using ASP.NET Core. • Implement database access with Entity Framework Core and the Repository Pattern. • Secure your APIs using ASP.NET Core Identity, JWT authentication, and refresh tokens. • Handle logging and monitoring with Serilog and health checks. • Add versioning, caching, and request throttling for scalable APIs. • Generate live documentation using Swagger / OpenAPI. • Troubleshoot, document, and test APIs with various tools • Apply dependency injection and AutoMapper for DTO mapping. • Deploy APIs to Microsoft Azure • Manage your source control with GitHub. Why Learn ASP.NET Core Web API? ASP.NET Core is Microsoft’s modern, cross-platform framework for building high-performance APIs that power enterprise systems, web applications, and mobile backends. Learning how to create and manage APIs enables you to connect applications, services, and clients — from Blazor frontends to mobile apps and third-party integrations. With C# and .NET Core, you gain one of the most in-demand skill sets in software development today — combining performance, scalability, and maintainability that organizations depend on. Who This Course Is For • Developers who want to build production-ready RESTful APIs with .NET Core. • Backend engineers interested in API security, architecture, and best practices. • C# programmers looking to apply their skills in real-world web development. • Anyone preparing for a .NET developer or Azure-focused backend role. Requirements • At least 3 months of C# experience • Basic understanding of object-oriented programming. • Visual Studio 2022, Visual Studio 2026, or Visual Studio Code installed. If you’re new to C#, take my C# Console and Windows Forms Development with LINQ & ADO .NET course first for a strong foundation. What Makes This Course Unique This isn’t just theory. You’ll build a complete API step by step, learn from real debugging scenarios, and see how professional developers structure their projects for maintainability and scalability. Every lecture includes practical examples, and all source code is hosted on GitHub so you can follow along and modify it for your own projects. By the end, you’ll know how to confidently design, implement, secure, test, and deploy ASP.NET Core Web APIs like a pro.
