Rajiv and Shipra Introduction to.NET (asp.net,c#,vb)

.NET –Framework It is a programming platform that is used for developing Windows and Web-based software. It has number of precoded solutions that manage the execution of program specifically for framework.NET framework platform is based on two technology XML(eXtensive Markup Language) The suit of internet protocol.

XML.Key feature of XML are. It unlock information that can be edited, programmed and organized. It allows website to collaborate and provides groups of web services. They can be interact with each other. It separate date from presentation.

.NET – What Is It? Operating System + Hardware.NET Framework.NET Application

Framework Class Library Common Language Runtime Common Language Specification ADO.NET Visual Studio.NET ASP.NET: Web Services and Web Forms Windows Forms Component of Frame work

The.NET Framework.NET Framework Services Common Language Runtime Windows ® Forms ASP.NET –Web Forms –Web Services ADO.NET, evolution of ADO Visual Studio.NET

Common Language Runtime (CLR) CLR :An Execution engine of framework CLR provides many features such as imposed by –Memory Management –Code saftety verification and Code execution –Error and exception handling –Garbage Collection

Compilation in.NET Code in VB.NETCode in C# Code in another.NET Language VB.NET compilerC# compiler Appropriate Compiler IL(Intermediate Language) code CLR just-in-time execution

MSIL.NET languages are not compiled to machine code. They are compiled to an Microsoft Intermediate Language (IL). CLR accepts the IL code and recompiles it to machine code. The recompilation is just-in-time (JIT) meaning it is done as soon as a function or subroutine is called. The JIT code stays in memory for subsequent calls. In cases where there is not enough memory it is discarded thus making JIT process interpretive.

Languages Languages provided by MS –VB, C++, C#, J#, JScript Third-parties are building –APL, COBOL, Pascal, Eiffel, Haskell, ML, Oberon, Perl, Python, Scheme, Smalltalk…

Windows Forms Framework for Building Rich Clients –RAD (Rapid Application Development) –Rich set of controls –Data aware –ActiveX ® Support –Licensing –Accessibility –Printing support –Unicode support –UI inheritance

ASP.NET ASP.NET is a technology used to create dynamic web application. It is based on.NET platform and support.NET compatible language for its application. Features Rich Class Framework:. Net Framework consists of around 4500 classes that encapsulate the rich functionality like XML data access, file upload, image generation and performance monitoring. Mobile Web Device Support: It provides mobile controls for developing mobile application. Using the application code, the mobile control auto generate WAP,WML.

ASP.NET Advantages –Powerful database-driven Support: It provides a toolbox with rich set of tools to assist in the coding and designing. The toolbox has been incorporate within the IDE like Drag & Drop facilities and automatic deployments. –Faster Web Application: Complication of code into machine language rather then interpretation of code makes ASP.NET web applications faster.

ASP.NET Web Forms Asp.net is 4 th generation language mainly used for dynamic web application. Feature Code-behind Web Forms Easier for tools to generate Code within is compiled then executed Improved handling of state information Support for ASP.NET server controls –Data validation –Data bound grids

ASP.NET Web Services A technical definition –“A programmable application component accessible via standard Web protocols”

IDE It provides a stranded text editor to write the.net applications. The Working environment of.net is know as IDE. It provides the common environment for designing,editing,debugging with in common environment is known as IDE. IDE has integrated compiler to compile and execute the application. The user can compile either single source file or complete project

ADO.NET (Data and XML) Development tool that contains a rich set of productivity and debugging features

.NET – Hierarchy, Another View CLR

Summary The.NET Framework –Dramatically simplifies development and deployment –Provides robust and secure execution environment –Supports multiple programming languages
