With a master degree in software engineering and more than 20 years of professional software development experience, I am excited to be an instructor on Udemy for sharing my knowledge and experience through this wonderful platform. I am a senior full stack developer with extensive experience in .NET technologies like ASP.NET, ASP.NET Core, as well as JavaScript frameworks like Angular, React and VueJs. I am also very experienced with data including SQL Server, Reporting, ETL, Azure Data Factory and Power BI. I have a passion of learning and sharing all my experience in development as well as design and architecture.
Besides technologies, I spend a lot time reading about philosophy, thinking and reflecting on life...

Having the old course version means that many topics already covered in the new one are repeated. However, the old course has some supplementary content that makes sense to include; it would be beneficial to incorporate it into the new course and delete the old one to avoid repeated topics.

Great course. Very knowledgeable. But, I did had to fix a few bugs a few times as I got errors he didn't get in the videos. This is to be expected as the technology changes. But, I do really enjoy the course and have learned so much valuable info - money well spent!

Great course for learning .NET Core Web API, even somebody works in still in .NEt 8 or .NET also right course for them, And starting with .NET Core 10 to learn Asp .NET for Full Stack Engineer journey one of the best courses to start.
By Rafał Kościński on 7/10/2025
I would givbe five starst if the course for new web api looked like the old one whene there is a lot more info. The new part looks like done very quickly just to have it and the sound somethimes is strange. Either microphone was changed, or it was heavily edited just to upload it. This course would be great if it looked like the old one but with new .net
By Dariusz G on 2/15/2025
I like the course. 5 stars with no doubt. Great knowledge, great preparation, great presentation and teaching skill. The only feedback for improvement I can leave is that you could prepare an environment or configure Postman with some variable in a way the token is automatically saved and used. You wouldn't need to deal with token so many times in the moment when you explain some different important things. Thank you for the course!

Everything is well-taught. I believe this is an amazing introductory course to ASP.NET Core Web API. I'd recommend anyone this to anyone that wants to try API development, and has a beginner to intermediate knowledge of C#. About the old course: there is a lot of outdated processes like versioning with OpenAPI and Swagger, and the use of Identity Server 4 (which is discontinued as of Nov 2022). However, I still recommend to watch the old course and take notes, like when using DTOs, the architecural problems of having the model classes and attribute filters within the API project, and so on. This is because some of these were not covered in detail in the new course videos. Anyways, thank you sir Frank for a great course. Keep up the good work. Cheers!

Fantastic course. 2 points of advice : 1) use a lower screen resolution, text is not very readable compared to a lot of tutorials. 2) Slow it down a little bit. Your pace is as if you are trying to go as fast as you can which causes students to constantly pause to keep up. The material and structure of the course is on point though, good work

This is just what I was looking for, and was unable to find it elsewhere. Especially the Identity Server 4 Authentication and Authorization piece for BlazorWasm + WebAPI combination. Thank you very much Frank Liu! Appreciate your effort. I had a use case involving implementation of SSO on top of OAuth, but adding SSO was easy after learning the basics of OAuth in BlazorWasm from your course.
By Goumatianos Nikitas on 4/12/2021
The course is focusing on Web API. I liked how it is organized. It explains the architecture of Web API including other parts (routing, repository, EF, authentication etc). I recommend this course. It has everything you need to design and build an enterprise app.
By Ionut Lazurca on 4/8/2021
Great course. After following Mr. Frank Liu courses I am really starting to understand Asp.Net Core technology with its DI implementations. I like the way it explains, first the fundamentals and then teaching you a custom implementation and then showing you the standard way of doing things. There are complex topics in this course like Versioning and authentication with IdentityServer. I have fallowed Youtube's courses as well from the teacher to get a better understanding of the concepts. I like that the teacher explains how's and why's a lot. Thank you very much Mr. Frank Liu!
