  1. ASP.NET &.NET Environment

  2. Overview • Part of Microsoft’s .NET environment • Used for Development of • Websites • Internet applications • Web Services & XML Web Services • Languages • VB.NET, C#, J# (others available) • Successor of ASP pages (but very different) • Event driven rather than script driven

  3. .NET environment • Common Language Runtime (CLR) • Basis for the .NET environment • Code is compiled to .dll files • A solution can contain code of multiple languages

  4. ASP.NET Components • Web pages (including data checking) • Code Behind Pages • For complex web solutions: • Master Pages (same look/feel for all web pages) • User Controls • Sitemap • Style Sheets AJAX control available

  5. Advantages • Faster than script-based languages since it is converted into precompiled dlls • Easier error handling (caught before run-time, allows try-catch blocks) • Can use existing controls and templates provided • An extensive set of controls and class libraries allows the rapid building of applications. • The Code-behind the interfaces can be coded in the language of preference • Ability to cache the whole page or just parts of it to improve performance. • Ability to separate the looks of the page and the code-behind. • The CLR will take care of garbage collection, and other basic functions • http://en.wikipedia.org/wiki/ASP.NET

  6. Disadvantages • Platform limitations - Windows • High memory usage and it can be slow at execution (development NOT user access) • Some backward and forward incompatibilities exist • Reverse-Engineering is possible • Code can be decompiled and can be put live with the actual code

  7. Comparing .NET to Other Approaches • Much debate • Many different opinions usually due to different backgrounds Very popular with Windows based customers (lots of jobs available)

  8. Conclusion: Depends…what you want to accomplish and what is the programmers background There are many tools existent to combine the different approaches
