.Net framework

BY:- ARUN PAL
FACULTY:- Mr. SATISH

The Microsoft.NET Framework is a software
framework .

 Supports C++ , C# , and J#.

Itincludes a large library of coded solutions to
common programming problems,and

 Virtual machine that manages the execution of
programs written specifically for the framework.

The .NET Framework is an integral Windows
component.

VERSIONS OF .NET
FRAMEWORK
.NET FRAMEWORK 1.0
 First release of the .NET Framework on 13-February-
2002.

 Available for Windows 98, Me, NT 4.0, 2000, and XP.
.NET FRAMEWORK 1.1
 This is the first major .NET Framework upgrade.

 As a software development kit, and was published on 3
April 2003.

 Included as part of the Windows operating
system, shipping with Windows Server 2003.

.NET FRAMEWORK 2.0
 Published on 22 January 2006.

 Released with Visual Studio 2005, Microsoft SQL Server
2005, and BizTalk 2006.

 Included as part of Visual Studio 2005 and Microsoft
SQL Server 2005.
.NET FRAMEWORK 3.0
 Released on 21 November 2006.

 Includes a new set of managed code APIs that are an
integral part of Windows Vista and Windows Server
2008 operating systems.

.NETFRAMEWORK3.0 CONSISTSOF FOUR MAJOR NEW COMPONENTS:

 WINDOWS PRESENTATION FOUNDATION

A new user interface subsystem and API based on XML and vector
graphics,

Uses 3D computer graphics hardware and Direct3D technologies.

 WINDOWS COMMUNICATION FOUNDATION

Service-oriented messaging system which allows programs to
interoperate locally or remotely similar to web services.

 Windows Workflow Foundation
Allows for building of task automation and integrated transactions
using workflows.

 WINDOWSCARDSPACE,
Stores a person's digital identities and provides a unified interface for
choosing the identity for a particular transaction.

.NET FRAMEWORK 3.5
 Released on 19 November 2007.

 Not included with Windows Server 2008.

 As with .NET Framework 3.0, version 3.5 uses the
CLR of version 2.0.
.NET FRAMEWORK CLIENT PROFILE
 Smaller than the full framework(28 MB) and only
installs components that are the most relevant to
desktop applications.

.NET FRAMEWORK 4.0
 New Visual Basic and C# language features, such as
statement lambdas, implicit line continuations, dynamic
dispatch, named parameters, and optional parameters.

 Full support for IronPython, IronRuby, and F#.

 Support for a subset of the .NET Framework and ASP.NET
with the "Server Core" variant of Windows Server 2008 R2.

 Support for Code Contracts.

 Inclusion of the Oslo modelling platform, along with the M
programming language.

.NET
FRAMEWORK
ADVANTAGES
 CONSISTENT PROGRAMMING MODEL

 Different programming languages to do a task

 for example, accessing data with a VB .NET and a C# .NET
looks very similar .

 DIRECT SUPPORT FOR SECURITY

 Develops an application that resides on a local machine and
uses local resources is easy.

 Simplified Development Efforts

 ASP.NET and the .NET Framework simplify development by
separating the application logic and presentation logic making it easier
to maintain the code.

OBJECTIVES OF .NET
FRAMEWORK
 Consistent object-oriented programming environment whether
object code is stored and executed locally, executed locally but
Internet-distributed, or executed remotely.

 Code-execution environment that minimizes software deployment
and versioning conflicts.

 Code-execution environment that promotes safe execution of
code.

 Code-execution environment that eliminates the performance
problems of scripted or interpreted environments.

 To make the developer experience consistent across widely
varying types of applications,

USES OF .NET
FRAMEWORK
We can use the .NET FRAMEWORK to
develop the following types of applications
and services:
 Console applications.
 GUI applications.
 ASP.NET applications.
 XML web services.
 Windows services.

TWO MAIN COMPONENTS OF .NET
FRAMEWORK
 COMMON LANGUAGE RUNTIME
 Virtual machine component .

 All .NET programs execute under the supervision of the CLR.

 Guaranteeing certain properties and behaviors in the areas of
memory management, security, and exception handling.

 BASE CLASS LIBRARY
 Part of Framework Class Library (FCL).

 Library of functionality available to all languages using the .NET
Framework.

 Provides classes which encapsulate a number of common
functions, including file reading and writing, graphic
rendering, database interaction and XML document manipulation.

DESIGN FEATURES OF .NET
FRAMEWORK
 INTEROPERABILITY

provides means to access functionality that is
implemented in programs that execute outside
the.NET environment.

 SIMPLIFIED DEPLOYMENT

Includes design features and tools that help
manage the installation of computer software.

 SECURITY
The design is meant to address some of the
vulnerabilities, such as buffer overflows, that have
been exploited by malicious software. So .NET
provides a common security model for all
applications.

 PORTABILITY
.NET Framework allows it to theoretically be
platform agnostic, and thus cross-platform
compatible.
