Why .Net?

Why C……..brainstorming Why Java …..Brainstorming Now why .net ??? Fast application development No new concept Fastest emerging technology in IT Market Job Oriented Has a wide range of applications Object Oriented(close to real world)


What is Microsoft .NET?

.NET is a Framework that provides a common platform for many languages.

44 languages in the beginning…..so can u guess what is the no now ???

The .NET Framework is an environment for building, deploying, and running Web applications and Web Services


Advantages of .NET Direct Support for SecurityConsistent Programming ModelWindows Presentation Format Support with XAMLIntelli-senseDebuggingGreatly simplifies language interoperability. Supports strongly typed languagesCalling from and to any other .NET language becomes simpleIt uses industry-standard protocols such as TCP/IP, XML, SOAP and HTTPEasy Application Deployment and MaintenanceSimplified Development Efforts


.NET Framework


.NET Framework

.NET Framework consists of 3 main parts: Common Language Runtime MSIL Framework Classes/Libraries

Common Language Runtime (CLR) A common runtime for all .NET languages

Common type system Common metadata Intermediate Language (IL) to native code compilers Memory allocation and garbage collection Code execution and security

Over 44 languages supported today C#, VB, Jscript, Visual C++ from Microsoft Perl, Python, Smalltalk, Cobol, Haskell, Mercury, Eiffel, Oberon,

Oz, Pascal, APL, CAML, Scheme, etc.


Common Language Runtime (CLR)CLR works like a virtual machine in executing all languages. All .NET languages must obey the rules and standards imposed by CLR. Examples: Object declaration, creation and use Data types,language libraries Error and exception handling Interactive Development Environment (IDE)


Intermediate Language (IL) .NET languages are not compiled to machine code.

They are compiled to an 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.

Common Language Runtime

Multiple Language Support CTS is a rich type system built into the CLR

Implements various types (int, double, etc) And operations on those types

CLS is a set of specifications that language and library designers need to follow This will ensure interoperability between languages


Common Language Runtime (CLR) Enables cross-language interoperability

Common Language Specification describes interoperability requirements

Language/Hardware/OS Independent Compact framework for small devices

Industrial strength Garbage collector Designed for multi-processor servers

.NET Framework Libraries

Single consistent set of object oriented class libraries to enable building distributed web applications (Unified Classes)

Built using classes arranged across logical hierarchical namespaces For example: System.Data.SQL

Work with all CLR languages No more “VBRun” or “MFC” divide

Controls, Caching, Security, Session, Configuration etc

Collections, Diagnostics, Globalization, IO, Security,Threading Serialization, Reflection, Messaging etc

ADO, SQL,Types etc

XSLT, Path, Serialization etc


ASP.NET ASP.NET is a new programming framework designed to

make web apps easier to: Build, Deploy, Run

Radical advancement of today’s ASP Broader programming language support

Visual Basic.NET, Jscript.NET, C# Easier page programming model

Namespaces Richer XML features and integration XCopy/FTP deployment Better reliability and recovery Excellent Visual Studio designer support


ASP.NET

ASP.NET is compiled, not interpreted Better performance Early binding, strong typing, JIT compiling to native code

Configuration settings in XML-based files Session state can now be shared across a web farm of ASP.NET

servers .NET State Server Process manages state

Application state is still single sever ASP.NET detects and recovers from problems

Access violations, memory leaks, deadlocks ASP.NET supports pre-emptive cycling of apps

Time and request based settings


ASP.NETASP.NET,the platform services that allow to program Web Applications and Web Services in any .NET language

ASP.NET Uses .NET languages to generate HTML pages. HTML page is targeted to the capabilities of the requesting Browser

ASP.NET “Program” is compiled into a .NET class and cached the first time it is called. All subsequent calls use the cached version.


Logical Evolution of ASP Supports multiple languages Improved performance Control-based, event-driven execution model More productive Cleanly encapsulated functionality

ASP.NET


ASP.NET Web Services

A technical definition “A programmable application component accessible

via standard Web protocols”


It is just an application… …that exposes its features and capabilities over

the network… …using XML… …to allow for the creation of powerful new

applications that are more than the sum of their parts…

Web Services


ASP.NET Server Controls

Server controls are tags that are understood by the server.

There are three kinds of server controls: HTML Server Controls - Traditional HTML tags Web Server Controls - New ASP.NET tags Validation Server Controls - For input validation


Allows clean cut code 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 Forms


ADO.NET (Data and XML)

New objects (e.g., DataSets) Separates connected / disconnected issues Language neutral data access Uses same types as CLR Great support for XML


Visual Studio.NET


Visual Studio.NET

Development tool that contains a rich set of productivity and debugging features


Visual Studio.NET

Integrated Development Environment Visual Basic.NET

Many language enhancements Inheritance,Overloading, Free Threading

Visual C++ Integration with .NET Framework with managed extensions (classes)

C# New development language Based on C/C++ with Garbage Collection/Memory Management

JUMP (Java User Migration Path) to .NET (1/25/01)

Visual J++ has been removed from the Visual Studio suite currently but it was a part of the earlier versions.


VS.NET Features

Single IDE for all Languages Server Explorer

Event Viewer, Message Queues, Services SQL Databases, Data Connection, Etc.

Integrated IE Browser HTML/XML Editors Macros/Macro Explorer Solution Explorer Tabbed Documents Dynamic Help Common Forms Editor

VB.NET, C++, and C#


C#


Intro to C#

Design Goals of C# Component Orientated Language Robust and Durable Software

Features Classes Namespaces No header files

VB.NET vs. C# Ability to embed C++ code in C# code Elegance of C/C++ language


Design Goals C#

Component Oriented Properties, methods, events

Robust and Durable Garbage collection (No memory leaks and stray

pointers) Exception Handling Type-safety (No uninitialized variables)

Based on C++ Interoperability

Support for XML, SOAP


IIS – Internet Information Services

Internet Information Service

IIS (Internet Information Services) is

Microsoft's Internet server

IIS comes as a free component with

Windows servers

IIS is also a part of Windows 2000 and XP

Professional

How to install


How does ASP.NET work?

Requests an HTML file, the server returns the file

Requests an ASP.NET file, IIS passes the request to the ASP.NET engine on the server

The ASP.NET engine reads the file, line by line, and executes the scripts in the file

ASP.NET file is returned to the browser as plain HTML


J2EE and .NET

Execution Engine J2EE

Java source code compiles into machine-independent byte code

Runtime Environment : JVM .NET

Any compliant language compiles into MSILRuntime environment : CLR

Both JVM and CLR ,support services, such as code verification, memory management via garbage collection, and code security

J2EE and .NET

Cross Platform Portability

J2EEPlatform Independent JDK should exist on target machine

.NETSupports Windows platformCLR should exist on target machine

Can support other platforms provided it has its own JIT complier

J2EE and .NET

Language Support

J2EE

Tied to Java

Supports other languages via interface technology .NET

Language independent

Supports any language if mapping exists from that

language to IL

J2EE and .NET

Tools Support J2EE

Can employ any number of tools

Pro :Developer has a great deal of choice

Con :Difficulty in choosing a right tool for a given job

.NET

Visual Studio.NET, single IDE for building an application
