ASP.NET Fundamentals and Disadvantages

ASP.NET is a server-side web technology developed by Microsoft to build dynamic, interactive, and database-driven web applications.
It is a subset of the Microsoft .NET framework.
ASP.NET is the successor to classic ASP (Active Server Pages).
ASP.NET utilizes HTML and server-side scripting to generate dynamic and interactive web pages and applications.
It utilizes the .NET framework, which is object-oriented and contains all web-related functionalities.
ASP.NET application codes can be written in languages like C#.NET, Visual Basic.NET, JScript.NET, and J#.NET.

Poor Reusability: ASP pages are interpreted and executed line-by-line, making it difficult to reuse pages in other applications.
Limited Functionality: Scripting languages have limited functionality compared to programming languages, impacting the development of complex web applications.
No Code-Presentation Separation: ASP scripts are mixed with HTML code, making it difficult to understand and maintain applications.
Poor State Management: ASP lacks built-in support for retaining HTML form states, requiring additional code for data management.
Limited Browser Support: Different browsers support ASP to varying degrees, necessitating multiple versions of code for compatibility.

Support for .NET Framework: ASP.NET leverages the .NET Framework, providing access to numerous classes and functionalities.
Programming Language Support: ASP.NET supports various programming languages, offering flexibility for developers.
Platform Independence: ASP.NET applications are platform-independent, allowing them to run on different operating systems.
Web Services: ASP.NET enables the development and consumption of web services, facilitating communication across different platforms.
Client Platform Independence: ASP.NET applications can be accessed from various devices and browsers.

ASP.NET Web Forms Pages: Provides a structured approach to building web pages with controls and event-driven programming.
ASP.NET Controls: Pre-built components for common web elements like buttons, text boxes, and data grids.
Cross-Language Support: Allows developers to use different programming languages within the same application.
Event-Driven Programming Model: Facilitates an event-driven approach to web development, making it easier to manage user interactions.
Data Access (ADO.NET): ASP.NET utilizes ADO.NET for data access, enabling interaction with various databases.
Session State Management: Provides mechanisms for maintaining session state, preserving user data across page views.
Deployment: ASP.NET applications can be deployed by copying files to the appropriate directory on the web server.
Error Handling, Debugging, and Tracing: Features for robust error handling, debugging, and tracing, enhancing application stability.
Security Management: ASP.NET supports authentication, authorization, and impersonation for secure access control.

The .NET Framework 2.0 was released after the success of version 1.1, focusing on increasing developer productivity.
It introduced enhancements in ADO.NET like asynchronous database operations, improved XML data types, user-defined types (UDT), and snapshot isolation.
Significant advancements were made in ASP.NET, including new data controls, enhanced code-behind model, caching features, and more.

64-Bit Platform Support: Enables the creation of applications that can take advantage of larger memory capacities.
Access Control List Support: Provides a mechanism to grant or revoke permissions for accessing computer resources.
ADO.NET Enhancements: Includes new features like user-defined types, asynchronous operations, XML data types, large value types, and snapshot isolation.
Security Enhancements: Improved security features for authentication, authorization, and cryptography.
New Controls and Components: Introduction of new controls and components for ASP.NET, enhancing development capabilities.
Visual Studio Integration: Enhanced integration with Visual Studio, improving the development experience.
Windows Forms Enhancements: Improvements to Windows Forms, providing new features and functionalities for desktop application development.
Web Services Enhancements: Advanced features for creating and consuming web services.
Language Enhancements: Enhancements to programming languages like C# and Visual Basic.NET.
Installation and Configuration: Simplified installation and configuration processes for the framework, making it easier to deploy applications.
