The online training in this course set a good foundation that can be applied practically. The online classes were brilliant and Mr. Shailendra took each class with lot of examples and explanations. his style of training was easily understandable and informative. The course was very useful for me to develop .net MVC, RAZOR framework and Web API applications. All sessions are interactive sessions, and Mr. Shailendra answered all the questions raised during the online training. The course fee is very nominal and the course really helps me in understanding the developing the .net Applications.
