About This Free Course
A Web API is an application programming interface for the Web. With Web API, you get access to entire features of HTTP like URIs, request/response headers, content formatting, etc.
This course will teach you all you need to know to build personal or commercial applications using Asp.Net Core Web API as your development framework. You will start from just Visual Studio and build your app from the ground up.
As data storage, you will use an SQL database and Entity Framework will be used to interact with your data. You will also learn how to update database schema using Entity Framework migrations, how to add data to the database, get data from the database, update data in the database and also delete data from the database.
You will not only learn about the default features or capabilities that Asp.Net Core Web API has to offer, but you will also create your custom implementations like for example a custom Web API return type.
You will learn all these, step by step with hands-on practice. You will also have a lot of quizzes that will help to improve your knowledge of Web API.

Who Should Take This Course
"ASP.NET CORE WEB API | The Complete Guide" is aimed at people who want a practical, structured introduction to development without paying full price for it. It's a solid fit if you're starting out in development and want a guided course rather than piecing tutorials together yourself, if you've tried free YouTube content on the topic and want something more organized in around 2, or if you already work in a related area and want a refresher you can finish at your own pace. Since enrollment happens on Udemy itself, you keep full access to view the lectures, download any provided resources, and revisit the material later — this isn't a stripped-down or time-limited version of the course.
Why This Course Is Worth Taking
Our take: this listing earns a spot on FreeWebCart because the coupon we verified actually brings the price to $0, not just a token discount, and the course carries a 4.3/5 rating on Udemy. That combination — real reviews plus a working 100% OFF code — is what we look for before publishing a development course. It won't replace hands-on experience or a full degree program, but as a low-risk way to test whether development is worth pursuing further, or to pick up one specific skill, the free price tag makes it an easy yes while the coupon lasts.
