ASP.NET is a core subject in the domain of Computer Science and Information Technology, essential for students aspiring to build modern, dynamic, and secure web applications. This subject introduces learners to the powerful features of Microsoft's.NET framework, enabling the development of scalable, high-performance web applications using server-side technologies.
This textbook content has been developed as per the syllabus prescribed by Osmania University. It aims to provide a clear, accessible, and up-to-date introduction to the concepts, tools, and techniques required for developing web applications using ASP.NET.
The primary objective of this book is to empower students with the skills and knowledge – required to design, code, and deploy ASP.NET applications. Beginning with the – foundational elements of the framework, the book explores advanced concepts such as state management, authentication and authorization, ADO.NET integration, web services, error handling, and configuration management. Emphasis is placed on practical implementation through examples, exercises, and real-time scenarios.
