RESTful Web API in .NET Core - The Beginners Guide (.NET 10) (Udemy.com)

Build RESTful web API (C#) with Authentication and learn how to consume them in a real world application (.NET 10 API)

Created by: Bhrugen Patel

Last updated February 2026

Our take

Based on the ratings of 7,998 students, a sample of their written reviews and the syllabus, as the course stood in February 2026. No course pays to be reviewed.

Bhrugen Patel's course is a build-along for a .NET 10 Web API, about seven hours across 114 lectures. It starts with endpoints and a SQL Server database through Entity Framework Core, then moves to validation, JWT authentication with .NET Identity, an API assignment and versioning. Midway it builds an MVC web app that consumes the API, login screens included. The title says beginners' guide, but the requirements ask for roughly six months of C# and some .NET Core experience.

Praise centers on the teaching style. Reviewers call the explanations clear and easy to follow, including for non native English speakers, and one praises the step-by-step walk-through. The complaints are just as consistent. Several 1 and 3 star reviewers say code gets typed with little reasoning behind it, that things change in the background without comment, and that they could not write anything alone afterward. Others report runtime errors, web pages that stop working after the versioning section, and a missing certificate. Still, most of the nearly 8,000 reviews are 4 or 5 stars, and only around 200 give one or two.

The course is short, so it covers the path through an API project rather than the depth. It was last updated in February 2026, so the .NET 10 tooling is current. We would point it at developers who already read C# comfortably and learn by following along. If you need the theory first or want each decision explained, pick something slower.

Best forC# developers with some .NET Core behind them who want to build, secure and consume one API from start to finish.
Skip it ifYou want every line explained in depth, or need cloud deployment and complex real-world scenarios.

Pros

  • Reviewers say the explanations are clear, even for non native English speakers
  • Covers JWT auth, .NET Identity, validation and versioning in one build
  • Consumes the API in an MVC app, so both sides of the call are shown
  • Refreshed for .NET 10 in February 2026, with Scalar docs instead of Swagger

Cons

  • Low-star reviewers say code is typed with little explanation of why
  • Billed as beginner-friendly, but it expects months of C# and .NET Core
  • Some reviewers hit runtime errors, and the web pages break after versioning
Complete and very well explained. It's also easy to understand for non native English speakers.
Hugo Barceló Díez, a student

Listed as intermediate. The requirements want about six months of C# and a few months of .NET Core first.

Course Description

Master the fundamentals of building and consuming RESTful APIs in this comprehensive beginner to intermediate course. Whether you're new to Web APIs or transitioning from traditional ASP.NET, you'll gain a solid foundation in creating professional APIs that follow industry best practices.


Why This Course Is Different:

This isn't just another theory-heavy tutorial. You'll build a real, complete application from scratch, following the same patterns and practices used in professional development environments. By the end, you won't just understand APIs—you'll have built, secured, validated, versioned, and documented one with modern tools.

This course is fully updated for .NET 10 and uses Scalar documentation—the modern, next-generation alternative to Swagger UI. You're learning with cutting-edge tools that represent the future of API documentation, not outdated approaches from years ago.


What Makes This Course Unique:

Unlike other courses that teach APIs in isolation, you'll see the complete picture: building the API, implementing proper validation, securing it with authentication, versioning it for real-world scenarios, documenting it beautifully with Scalar, and then consuming it in a full ASP.NET Core MVC web application. This end-to-end approach gives you the foundational skills that prepare you for professional development environments.


What You'll Learn:

Start with the fundamentals of RESTful API design and build a complete Web API from the ground up. You'll master all four HTTP methods (GET, POST, PUT, DELETE) and understand when and how to use each one effectively in real-world scenarios.

Implement robust validation in your API using Data Annotations and custom validation logic. You'll learn how to validate incoming requests, return proper error responses, and ensure data integrity at the API level—a critical skill that many courses overlook.

Work with Entity Framework Core and Code First migrations to manage your database schema. You'll learn how to design models, create migrations, seed data, and maintain your database structure as your application evolves.

Secure your API with Authentication and Authorization, implementing JWT tokens and role-based access control to protect your endpoints. You'll understand the difference between authentication and authorization and implement both correctly, ensuring only authorized users can access protected resources.

Implement API versioning strategies to manage your API evolution gracefully. Learn how to introduce new versions while maintaining backward compatibility for existing clients—an essential skill for any API developer.

Document your API professionally using Scalar documentation, the modern successor to Swagger UI. Scalar provides a beautiful, interactive, and user-friendly documentation experience that makes your API accessible and easy to understand. You'll learn why Scalar is rapidly becoming the industry standard for API documentation.

Build a complete ASP.NET Core MVC Web Application that consumes your API using HTTPClient with the Services. This is crucial—many courses teach you to build APIs but skip the consumption part. You'll implement the entire flow: making HTTP requests from your MVC controllers, handling responses, managing authentication tokens, displaying data in views, and handling validation errors gracefully in the UI.


Who This Course Is For:

This course is perfect for developers who want to break into API development and build a strong foundation. Whether you're building your first API or want to learn modern best practices with the latest tools like Scalar, you'll gain practical, hands-on experience you can build upon.


Why These Skills Matter:

In professional development, APIs must be validated, secured, versioned, and well-documented. Knowing how to consume APIs from web applications is equally important. This course teaches you both sides—building solid APIs and integrating them into real applications—giving you the essential foundation that prepares you for more advanced concepts.

Complete Learning Resources:

All source code and exercise solutions are available on GitHub, so you can reference the complete working code anytime. Details are provided in the "PROJECT RESOURCES" lecture.


Your Path Forward:

This is Part 1 of a two-part series designed to take you from fundamentals to advanced concepts. After completing this course, you'll have a solid foundation in API development with validation, authentication, versioning, and modern documentation. You can then continue to Part 2, where we'll build on this same project with advanced features like refresh tokens, file uploads, dynamic base services, advanced exception handling, and Azure deployment strategies—transforming your API into a truly production-ready application.


Build your foundation today and set yourself up for success in modern .NET API development!

amazing, before Starting this Course, I was checking feed back as well as the doubts and Questions by some others Students/people , I was scared for a moments , I was thinking, that many of em are against this Course as well as UDEMY as they got stuck faced some/many Errors and left it. But When I started I Faced few errors the reason was only when My "Auto-Completion" was ON in Visual Studio (XD) . Otherwise the Tutor is Knowledgeable ass well the walk-through with each and Every steps was amazing. I was thinking if there was azure and Amazon deployments as well as even some other clouds deployments course available that would be a Great.

By Garrett Gilliom on 10/25/2025

Great course to learn about how these API and web projects are built from scratch. Integrating with 3rd Party tools, setting up working auth, and covering deployment were areas I didn't expect to be exposed but am glad were included! I've learned a ton about APIs and how they can service web projects and am confident I'll be able to build my own projects own my own moving forward now. Thank you for this awesome course and your valuable instruction!

I recently completed the RESTFULL web api Course, and I must say it was an incredibly valuable learning experience. Whether you're a beginner looking to understand API concepts or an intermediate developer wanting to sharpen your skills, this course offers a well-structured and practical approach to mastering RESTful APIs.

By Marcelo Lopes Rodrigues on 4/18/2025

Mr. Bhrugen Patel speaks in very clear English and at an excellent pace. Each video is properly edited, and we students are spared things like typing time, minor typos and their corrections, and package download waits. As a result, almost no time is wasted, and the total duration of the course is significantly reduced. Another key point is that each step can be easily followed through the GIT commits, which is extremely important for those who want to follow each class in the course without having to type all the code, while still being able to test it at the end of each lesson. Every step is explained, its practical effects are demonstrated, and considerations about other possible scenarios are provided. I posted a question during the course, and it was answered the next day. Well done. I highly recommend this course. Congratulations, Mr. Bhrugen.

This course is truly a treasure for those who already possess some knowledge about C# and MVC. It's not necessarily the right place to start your learning journey if you're a complete beginner, but once you've dipped your toes into the subject, this course is nothing short of essential. It delves deep into complex concepts with clarity and precision, providing an enriching learning experience. The instructor’s expertise is evident, and the course layout is thoughtfully designed to enhance understanding. Additionally, the real-world examples help in solidifying the knowledge and understanding the practical applications of the concepts. A unique feature of this course is that it doesn't just spoon-feed you the information, it motivates you to think and explore beyond the curriculum. This approach makes the learning process much more engaging and gratifying. In conclusion, this course is an excellent investment. It's more than just a learning resource, it's a comprehensive guide that paves the way to becoming proficient in C# and MVC. Highly recommended!

By Abhishek Kumar on 5/28/2023

I would suggest this course who is looking to study .NET Core 7. The way of teaching was good and if you follow perfectly, you will never run into errors. If you do run into error go back and watch again, you may have missed something. This course may look like a 9 hr course but trust me it will consume more than 30-40 hours just to finish this course. Because as a beginner you need some extra time to understand some things before directly writing that code.

By Ibrahim Sharkas on 11/11/2022

ok i finished 70% of the course its good and i recommend it for any one who want to learn about api but the only problem is the instructor does not always reply to questions i would give 5 stars if he would reply for them as for the course itself it was well planned and layed out easy for me to follow

By Andriy Belizky on 2/26/2022

This is easy to follow and hands on course you must attempt if you are serious about understanding API, Web Services - this course is a must. I love it how the author programmes the project from start to finish (including debugging) - it helps to understand the flow of logic and general structure of process. Thank You so much for this awesome course - I am hoping to see more courses on Xamarin(MAUI), WPF, React, Blazor, with more types of projects,

By Paül Sánchez on 11/15/2021

Only critic i found is in lesson 86, he did skip a few steps. For whatever reason he simply separated some configurations from one class to another without showing it, the lessons starts with him saying we have this!, and you may spend a few minutes wondering where it came from... (don't bother) Just go to his Github on through dotnetmastery.com on Courses -> Details. create the classes on your solutions and copy->paste!. Not a deal breaker for me. BUT! i know a few people that would give him 1 star for this.

I learn a lot of new stuff

By Jorge A on 11/14/2020

Really good introduction to creating an ASP.NET Core Web API and consuming it from an ASP.NET MVC application. Covered enough to get a feel for all the basics. The only aspect of the course I wasn't a fan of was the use of Visual Studio instead of Visual Studio Code. Using VS Code would have been great for non-Windows users who are looking to try out .NET's cross-platform capabilities.

By Anthony McEvoy on 11/7/2020

The course is great for beginners to learn how to use ASP.Net Core MVC and Web API. It is also a good intro to Authentication. I was a little disappointed to see open text passwords stored in the database as this should never be done and I think this should have been emphasized more as beginners who this course is aimed at may not be aware of this.
