Kuldeep Chand I have tried my best to compile each and every aspect related to Core ASP.NET WebForms with C# in this eBook with various kinds of Simple and Professional Level Web Applications Based Example Programs using Visual Studio’s Wizard and Manual Coding. It have latest content on ASP.NET and I have tried my best to clear each and every Core Concept like ASP.NET WebForms, Webpages, Context, Events, HTML Forms, States, Web Controls, HTML Controls, State Managements, etc… in as easy language as possible. But since, the Whole ASP.NET is very big subject, so I have divided it in two parts to cover each and every aspect of it. This EBook covers only Core Concepts while another eBook covers Advance Concepts of ASP.NET WebForms. I believe that no other Core ASP.NET WebFomrs with C# Book has as much and good content as in this eBook is in Hindi Language because I have tried my best to include each and every core concept related to ASP.NET and I wish, each and every buyer would be happy with the content of this eBook. If you read this EBook, you will sure get Good Understanding of Core Concepts of ASP.NET WebForms to develop a Professional Level Web Application very easily plus this Core Concept is also compulsory to learn if you want to become a Professional ASP.NET MVC Web Developer because Microsoft’s ASP.NET MVC and ASP.NET Webpages are based on these core concepts too internally.
