Introduction of ASP.NET ASP.NET is a web application framework developed and marketed by Microsoft, that programmers can use to build dynamic web sites, web applications and web services. First released in January 2002 with version 1.0 of the.NET Framework. The successor to Microsoft's Active Server Pages (ASP) technology. ASP.NET is built on the Common Language Runtime (CLR), allowing programmers to write ASP.NET code using any supported.NET language. Bina Nusantara References:

Introduction of ASP.NET (Continue...) History: – In 1997, The research for new web application model to solve common complains about Active Server Pages, especially with regard to separation of presentation and content and being able to write “clean” code. – The research is done by Mark Anders, a manager on IIS Team and Scott Guthrie, Duke University graduate who join Microsoft in 1997, the initial design finished in two months around Christmas holidays in – The initial prototype was called “XSP”, the initial development was done using Java, but it was soon decided to build the new platform on top of the Common Language Runtime (CLR) instead. – With the move to the Common Language Runtime, XSP was re-implemented in C# (“Project Cool”) and renamed to ASP+, by this point the new platform was seen as being the successor to Active Server Pages, and intention was to provide an easy migration path for ASP developers.

Introduction of ASP.NET (Continue...) History (Continue…): – ASP+ first demonstrated at ASP Connections conference in Phoenix, Arizona on May 2, The initial beta release of ASP+ came at 2000 Professional Developers Conference on July 11, 2000 in Orlando, Florida. – During Bill Gates ’s keynote presentation, Fujitsu demonstrated ASP+ being used in conjunction with COBOL, and other languages such Microsoft’s new Visual Basic.NET, and C#, as well as Python and Perl support by way of interoperability tools created by ActiveState. – Once the “.NET” branding was decided on in the second half of 2000, it was decided to rename ASP+ to ASP.NET.

Introduction of ASP.NET (Continue...) Problems with Traditional ASP: – Interpreted and Loosely-Typed Code (impede performance, late binding) – Mixes layout (HTML) and logic (scripting code) – Limited Development and Debugging Tools (Microsoft Visual InterDev, Macromedia Visual UltraDev) – No real state management (Session state is only maintained if cookies supported) – Update files only when server is down (current components locked and new one must be registered) – Obscure Configuration Settings (arduous task to port from one server to another) Bina Nusantara References: Performance Tuning and Optimizing ASP.NET Applications (Jeffrey Hasan and Kenneth Tu,2003)

Introducing ASP.NET Applications Benefits: – Developed using compiled code and can be written using any.NET-compliant language including VB.NET, C#.NET and J#.NET. (Separation of Code from HTML, and Support for compiled languages) – Built into the.NET Class Framework -> benefits from an extensive API as well as all the benefit of the.NET managed environment, including type safety, Multilanguage support, optimized memory management, and a just-in-time (JIT) compilation model that optimizes the availability and performance of the application at runtime. (Use services provided by the.NET Framework) – Provides an extensible architecture that you can easily customize (direct access to context objects including HttpRequest, HttpApplication, and HttpSessionState objects). (State Management) – XML-Based Configuration files Bina Nusantara References: Performance Tuning and Optimizing ASP.NET Applications (Jeffrey Hasan and Kenneth Tu,2003)

Introducing ASP.NET Applications (Continue…) Benefits (Continue…): – The runtime engine executes in a separate process from Internet Information Server (IIS) and it delegates HTTP requests across a range of customizable handler classes. – Provides several ways to cache page content (full-page, partial-page) and Cache API. – Provides sophisticated debugging and tracing abilities. – Provides several methods for authenticating clients including Windows, Forms-based, Passport-based and standard IIS authentication (impersonation). – Graphical Development Environment with Visual Studio. (drag-drop, full intelliSense support for code, HTML and XML) – Update files while the server is running Bina Nusantara References: Performance Tuning and Optimizing ASP.NET Applications (Jeffrey Hasan and Kenneth Tu,2003)

Overview Of ASP.NET (Continue…) Common Language Runtime – Responsible for executing application code. – The code written is compiled into MSIL. (Microsoft Intermediate Language) – When the application execute, MSIL code compile into machine code by JITTER (the Just-In-Time compiler). (The code compile is just the method that are actually called during execution) – In the reality,.NET Framework understand only one language: MSIL. However, for writing application using language such as Visual Basic.NET and C# for.NET Framework because.NET Framework includes compilers for these languages that enable compilation of code using these language into MSIL. – These other languages that supported by.NET: Ada, Apl, Caml, COBOL, Eiffel, Forth, Fortran, JavaScript, Oberon, PERL, Pascal, PHP, Python, RPG, Scheme, Small Talk, etc. Bina Nusantara References: ASP.NET 3.5 Unleashed (Stephen Walther, 2008)
