"I have completed other courses on C#. Whiles 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

"Concepts are explained in very well manner" - Akanksha

"Great course, Focused on point with no distractions, straightforward, highly organized and really great effort. Thanks." - Nishma

"I have some programming experience. I like the flow of the instruction, and the fact that the quizzes allow for some creativity" - Michael

"Best Teacher ever hope more success for you and more courses for us" - Mohmd alkhatib

"i am still on the first sections of the course , but i wanted to write this review because this is a very good course on C# ,very clear in depth explanation and cover all the topics of C# , i only wish i have found this course sooner . update , i finished have the course still think this is the best C# course i have taking so far." - Moustamid Karim

"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

"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

"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

So you have nothing to lose, sign up for this course and learn how to build C# Projects from scratch!

Key Points about this Course: 

  • All C# programs are demonstrated using 'Console Applications' and 'Class Library' projects in Visual Studio 2019 / 2022.

  • Each concept is first explained theoretically like understanding what is that concept, different types / syntax to write code. And then we will show the same with a real-world-like scenario. At last, I'll explain where exactly we use this concept in real-word applications.

  • All the concepts explained in both theoretically, diagrammatically and practically.

  • We use Visual Studio 2019 for up to C# 8; and Visual Studio 2022 for C# 9 and 10 features.

  • Video lectures are not downloadable.
