Testimonials
- "I have completed other courses on C#. While some of those instructors are trully excellent, including Moshe Hamedani, and othe courses on PluralSight, indeed i swore by PluralSight before coming to Udemy, Mr Vardhan has to be commended. This is trully the most comprehensive course a new C# learner needs to form a solid understanding not only of the basics but intermediate level subjects. If you want to learn C# and have full confidence that you are at least intermediate level after your course, take this course. Thank you sir for your dedication to the learner. Too often instructors create courses with the learner not in mind, but just to get something decent out there. This is so thorough and presented so that you will understand without ambiguity Thank you again sir!." - David Odoom
- "By the way, your content is the best for .NET so far! I'm not exaggerating or flattering. I really mean it! I've checked other .NET courses too, but they don't have the quality that your content has. Your content not only helps to lay basic foundation of the concept, but it also enables to think and tackle the advanced use cases. And the beauty is that your course is absolutely consistent with the official docs. Please make more content." - Asadullah Ehsan
- "Great course, Focused on point with no distractions, straightforward, highly organized and really great effort. Thanks." - Nishma
- "As a computer engineering graduate, I can easily say that this course really helped me to brush up my C# skills and the tutor (Mr. Harsha) is a caring person. He usually answers your questions in 12 hours." - Tayfun Odabaşı
- "I have some programming experience. I like the flow of the instruction, and the fact that the quizzes allow for some creativity" - Michael

- "I like the background info. Extra effort was put in the graphics. I'm early in the course, but look forward to the rest.." - Mark Workman
- "Concepts are explained in very well manner" - Akanksha
- "This course is amazing! Such a great instructor. Concepts are clearly and intelligently presented. I have a few C# courses and this one is by far my favorite. He doesn't just touch on a topic and bam you're on to the next one. He gives several examples and by the time that section is finished, you feel you really understand that concept. I can't give this course enough praise! I'm a professional C# dev and this course is helping fill in the gaps of my understanding. Thank you for such a great course!" - Business
- "Incredible course for anyone looking to start with C# and OOP. I'm halfway through, and thus far every single concept has been explained in an easy-to-understand manner. The instructor also does a fantastic job of reinforcing the topics he's discussing by reiterating them multiple times in different ways and in different scenarios." - Vincent

By sujal ghimire on 10/14/2025
so yeah from someone with no prior coding experience , this course is really good and beginner friendly , he teaches very slow and methodically so it really helps a beginner like me , i also have a c# book so that helps me when practicing the concepts such that i am retaining quite alot of what he has been teaching. Thankyou for this course and will edit my review if possible after I finish this course.

After a four-year break from C#, I enrolled in the "C# OOP Ultimate Guide Project Master Class" on Udemy to refresh my skills and fill in some foundational gaps. The course starts with a solid overview of C# basics, which was great for reorienting myself. It then delves into object-oriented programming concepts like inheritance, polymorphism, and interfaces, reinforcing my understanding with practical examples.
By Marcin Vu Van on 12/11/2024
The course contains a great deal of knowledge however there are things that could be improved: - while some viedeos are longer and can take up to 23 min the instructor cover the topic in depth, instead he explains the concept within the first half of the video and proceeds to repeat himself in the second half, which is fair and good for topic comprehension but makes in much harder and less pleasant to go through the course - the course lacks materials to practice on, if we gain some knowledge about some topics and dont get to practice them its hard to use them later on or when the need for them arises. those assignmetns that are already present could be made harder or longer. - this course is supposed to be advanced c# but it still lacks a lot of topics such as reflection, attributes etc. while it contains a lot of knowledge i wished to learn almost everything there is to learn about c#, yet i found out there are still some stuff that were not covered in thsi course - still worth the money though, just wished there would be a bit more
By Glenville Maturan on 5/13/2024
This course caters perfectly to both beginners and intermediate C# developers seeking to enhance their skills. The topics are meticulously structured and logically divided into sections. The detailed notes accompanying each topic are incredibly helpful. The inclusion of assignments within each section provides a valuable opportunity for self-assessment. One standout feature of this course is its depth. It covers theory, basics, intermediate, and advanced concepts related to C# comprehensively. I rate it 4/5 due to a few minor drawbacks: - Some topics could benefit from more concise explanations, as overly lengthy explanations can lead to confusion. - Certain topics could be condensed to reduce the time required for completion, addressing the previous point. - The answers to interview questions tend to be verbose; succinct responses would better showcase understanding. - The instructor, while knowledgeable, is not a native English speaker, leading to occasional mispronunciations and lengthy grammar. In summary, this course offers extensive coverage of C# programming and provides valuable insights applicable to real-world scenarios. It stands out as one of the most comprehensive C# courses available on Udemy, covering topics beyond just the basics. I highly recommend it for anyone looking to deepen their understanding of C#.

Harsha's course stands out as one of the best I've enrolled in on Udemy. His didactic teaching style, combined with his evident expertise and deep knowledge of the subjects, creates an engaging and insightful learning experience. As I look forward to starting the ASP.NET Core 7 Course, I have high expectations based on the quality and value of this course. It's evident that Harsha's courses are meticulously crafted, comprehensive, and impactful. I wholeheartedly recommend his courses to anyone seeking a thorough and engaging learning journey!
By Andres BENAVIDES on 12/26/2023
Harsha is a great instructor, explains everything at a great pace with thorough examples. Provides a complete pathway to comprehend the fundamentals of every topic and connects the ideas in a way that you get everything he is teaching as easily as it can get. Used a lot of the concepts he teaches in real projects.
By Dominik Osak on 12/9/2023
My first impression of this course was not very good, but after watching the whole thing, I somewhat reversed my opinion. Disadvantages: - too much theory, - too little practice. Advantages: - a lot of explaining and clearing difficult topics, - a lot of hours of the course
By Kristy on 6/30/2023
It's a super comprehensive course on C# that covers all the essensial language concepts in depth! I would recommend it to anyone wishing to get to know C#, it's super beginner-friendly so don't hesitate and give it a shot! I have just finished this course and I'm super excited to go into Asp.Net Core course taught by Harsha. Unlike others who left reviews here, I liked the repetition of some concepts here and there throughout the course. It does the job and I memorized concepts much easier with this approach. It could take you some time to get used with the instructor's accent but it all was super worth it, thank you for the work you've done, Harsha, this course is awesome!
By Mervin Wee Shanming on 5/1/2023
It is primarily because of this course, amongst several others, that helped me so much in my mid-career transition in getting a developer job, and it still is a wonderful reference material for anything in C# that I need. The details were sufficient for anybody to understand them well. Thank you Harsha for creating this amazing course. There are a couple of topics that I felt were rather important but were excluded in this course: Reflection and Expression Trees. Hopefully one day these could be added in with some examples, perhaps as an "Advanced" section. Also sometimes I think the videos were a little too lengthy, perhaps planning and scripting can help to reduce the length of these videos, but yet without reducing their content. This would help give time for additional topics if possible.
By Shekar Reddy on 6/22/2021
Harsha is a highly competent, adept and experienced developer and instructor. He teaches the latest technologies. This course is on steroids! I got a wealth of information from his course and have purchased his other courses too. I'm going to watch the course many more times due to the depth of the course. An amazing course from an awesome and passionate instructor!!
