Creating Minimal Web APIs with .NET Online Course
Creating Minimal Web APIs with .NET Online Course
In this introductory course on Creating Minimal Web APIs with .NET, you’ll learn how to build lightweight HTTP APIs with minimal dependencies, ideal for microservices and optimized ASP.NET Core applications. The course begins by introducing the concept of minimal APIs, their advantages, and when to use them. You’ll also explore the differences between Minimal and MVC APIs. Key topics include implementing collection APIs, working with Entity Framework, Dependency Injection, and asynchronously returning results in Minimal APIs. Additionally, you'll learn about Data Transfer Objects (DTO), AutoMapper, exception handling, and creating individual item endpoints (GET, PUT, DELETE). By the end, you’ll be equipped with the skills to build and implement Minimal APIs for your RESTful API projects, following a practical, step-by-step approach.
Key Benefits
- Gain the skills to design and develop RESTful APIs from the ground up, tailored to your specific needs.
- Learn how to build a Minimal Web API using .NET Core, positioning yourself ahead in the competitive job market.
- Apply API development principles to scale and optimize distributed computing, enhancing the performance of your real-world applications.
Target Audience
This course is designed for web developers who are involved in consuming or exposing APIs, whether collaborating with internal teams or third-party services. It is also ideal for software architects looking to leverage API concepts to scale and optimize distributed computing in their projects. Participants should have a foundational understanding of RESTful API design and possess access to a PC running Windows, macOS, or Linux, equipped with Visual Studio Code (or a similar IDE capable of building C# projects) to fully engage with the hands-on exercises and activities throughout the course.
