Software Development India

Design patterns were brought to the software community in a book coined Design Patterns, written by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides (known as the “Gang Of Four”).
The core concept on which design patterns were based, presented in the introduction, was simple. Over their years of developing software, Gamma et al found certain patterns of solid design emerging, similar to an architects designing houses and buildings can develop a blueprint for where a bathroom should be located or how a kitchen should be looking. Having those blueprints, or design patterns, means they can design much better buildings more quickly. The same concept applies to software development as well.

ASP.net was developed by Mark Anders and Scott Guthrie after the release of Internet Information Services 4.0 in 1997. It’s initial prototype was called “XSP” and was created by using Java. Earlier lots of features like garbage collection etc. were not provided by Microsoft. As “XSP” was built on the top of Common Language Runtime (CLR), it provided lots of features which were proposed but not yet implemented by Microsoft. It offered an object-oriented programming environment.

XSP was re-implemented with the intention to provide as an easy migration path for ASP developers using C# and renamed as “ASP+”. Now ASP+ was used in conjunction with COBOL and support for a variety of other languages like Visual Basic.NET, C#, Python, Perl etc.

After four years of development, ASP.net 1.0 was released on January 5, 2002 with lots of features like Code behind Model, interactive user controls, better user authentication with accounts and roles, rendering technique, state management etc. With ASP.net, the gap between writing Windows-based applications and Web-based applications has been closed.
