"I’ve actually landed my first job as a Junior software developer. I owe a lot of it to you because your courses have been EXTREMELY helpful. May God bless you and your efforts to create high quality courses. This has really changed my life from working as a security guard and doing websites for free, now I am a professional." -Danish Jafri
"Just finished this course today, it was absolutely brilliant! They way the course boils down huge topics, that would take hundreds of dry boring text books into short videos, while including not only theory but how professionals make the most of the concepts. The Man has serious passion about Development, his enthusiasm and experience really make these dense topics fun & easy to learn!" -Conor McGarth
"This guy really knows what he is doing. I have been a developer for a while and he really knows how to break down what happens behind the scenes and how to create code that is extensible and reusable. I had peers telling me that paying for a course is not worth it but I went ahead and did it and I have learned so much from the videos. This course is definitely worth the price." -Justin Weinzimmer
"Mosh is a great teacher, explains things clearly, his lessons have a nice logical order, the course is engaging, he never bores, he DOES answer every single question. Highly recommended!" -Frantisek Nagy
"Excellent! Another brilliant piece of instruction... I have grown to expect nothing less from Mosh!" -Douglas Crowder
"One of my favorite aspects of Mosh's teaching style is his effort to retain relevance to real-world situations. As an experienced C# developer myself, I can tell you pretty much every topic in this course is important to a .Net developer, and Mosh does a good job of separating what you should understand conceptually versus how you'll likely be using the concepts in practice." -M.B
"The information that Mosh provides is extremely helpful. He does a great job of explaining things. Mosh has an interesting and fun style of presenting information. He covers the topics thoroughly and responds to questions in the discussions." -Jon Ownbey

I purchased this course because I need a refresher course in preparation for my technical interviews. In my previous job I was stuck in using the company owned development software and we rarely use any back-end programming in .Net either C# or VB; so while looking for a new opportunity in other companies, this course helped a lot for my technical interview preparation. The explanation is basic, though as for me, I do use the coding styles, but I do not know the technical terms of it, so this refresher course is really helpful for me. As a Senior Software Engineer, I realized I am only a Senior using the company development software but not in the back-end programming. So, thank you for this simple course.

I took this course as a refresher, having not done any coding for a few years after changing role. This has made my memory a lot less hazy and actually reminded me how much I used to enjoy coding as an activity in it's own right! Thanks Mosh.
By Gibril Njie on 4/24/2026
Perfect course for someone who wants to understand advance topics in C#, as the course is easy to follow and Mosh knows how to teach diffucult topics and concept in an easy to understand way. I give tjis course a 5 star.
By Maria Wisniewski on 4/21/2026
Thank you for this course, you plan them very well, and we find it easy to get through them. Some courses are just too much at once; your courses are piecemeal consumable! PS: Please include your code snippets for all the sections so that we follow along. It helps a lot if we can download it and run it in our IDEs.
By Het Patel on 4/6/2026
The course is well structured and I like the way you guided the track. When teaching a certain topic, there are so many branches one could take and it would become really complicated to follow the instructions. You try to keep the lecture focused on one topic while also revisiting the topics we have learned earlier.
By Carlos Antonio Barrera Maza on 3/30/2026
You need to master these topics as a professional .NET developer, if needed come back and watch each concept again. I think that I have now understood concepts that I have been using for years without knowing why, you need to know all the “tools” available so you can use the best tool for each job. Even though I have been a .NET Developer for so many years I appreciate how much I learnt on this course.
By Stefanus Foukaridis on 3/14/2026
I enjoyed the beginners and intermediate courses. The topics covered are just some of the "advanced" C# topics. Most of the content should have been covered in intermediate. Also disappointing that a course last updated in 2019 talks about C# 6 from 2015. Also explaining a lot of the content from an intermediate perspective. Would not recommend
By Saurabh Garg on 1/26/2026
The course was good, but it would be better if there were some exercises like that in the other beginner and intermediate course. Also The content was also limited, does not cover about threads or in depth knowledge. But overall for beginner who are really new to C# and wants to build fundamental, this course is good.
By Petr Kriz on 12/19/2025
Thank you for the practical course, we use everything in our embedded development wpf tool. This course show me, that we use C# in the right way. It recovers me some practice, what we have in our codes and take it as obvious, but it is good to see some theory and example to make all pieces to a one.
By Mubarak Bai on 12/18/2025
Well structured cours with talent of the techer to explain everything step by step in a very good way. There are a lot of courses for C#, which are created by diffrent Teacher, but Mosch is in my opinion is the best!
