The document discusses the Microsoft .NET Framework. It provides an overview of the different versions of the .NET Framework from versions 1.0 through 4.0. It describes some of the key components introduced in version 3.0 like Windows Presentation Foundation. It outlines some of the advantages of the .NET Framework like a consistent programming model and direct support for security. It discusses the two main components of the .NET Framework - the Common Language Runtime and Base Class Library. It also covers some of the design features of the .NET Framework like interoperability, simplified deployment, security, and portability.

2. 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.

3. 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.

4. .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.

6. .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.

7. .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.

8. .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.

9. .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.

10. 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,

11. 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.

12. 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.

13. 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.

14.  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.
