.NET Framework
HISTORY
The .NET Framework (pronounced dot net) is a software framework developed
by Microsoft that runs primarily on Microsoft Windows.

It includes a large library and provides language interoperability (each language can
use code written in other languages) across several programming languages.

 Programs written for the .NET Framework execute in a software environment (as
contrasted to hardware environment), known as the Common Language
Runtime (CLR), an application virtual machine that provides services such as
security, memory management, and exception handling. The class library and the CLR
together constitute the .NET Framework.

The .NET Framework's Base Class Library provides user interface, data
access, database connectivity, cryptography, web application development,
numeric algorithms, and network communications.

.NET Framework
HISTORY Conti….
Microsoft started development of the .NET Framework in the late
1990s, originally. By late 2000 the first beta versions of .NET 1.0
were released.

Version 3.0 of the .NET Framework is included with Windows
Server 2008 and Windows Vista.

Version 3.5 is included with Windows 7 and Windows Server 2008
R2, and can also be installed on Windows XP and Windows Server
2003.[2]

On 12 April 2010, .NET Framework 4 was released alongside
Visual Studio 2010.

The .NET Framework family also includes two versions
for mobile or embedded device use. A reduced version of the
framework, the .NET Compact Framework, is available
on Windows CE platforms, including Windows Mobile devices such
as smartphones. Additionally, the .NET Micro Framework is
targeted at severely resource-constrained devices.

NET Versions Conti…………
The Microsoft .NET framework also having a some diff. kinds
of versions ,which are use a such a special purposed……

 .NET Compact framework
The Microsoft .NET Compact Framework (.NET CF) is a
version of the .NET Framework that is designed to run on resource
constrained mobile/embedded devices such as personal digital
assistants (PDAs), mobile phones, factory controllers, set-top boxes, etc.
The .NET Compact Framework uses some of the same class libraries as the
full .NET Framework and also a few libraries designed specifically for
mobile devices such as .NET Compact Framework controls. However, the
libraries are not exact copies of the .NET Framework; they are scaled down
to use less space

It is possible to develop applications which use the .NET Compact
Framework in Visual Studio .NET 2003, in Visual Studio 2005 and
in Visual Studio 2008, in C# or Visual Basic .NET. The resulting
applications are designed to run on a special, mobile-device, high
performance JIT compiler.
.NET Micro framework

The .NET Micro Framework (NETMF) is an open source .NET platform for
resource-constrained devices with at least 256 Kbytes of flash and 64 Kbytes
of RAM. It includes a small version of the .NET CLR and supports development
in C#, Visual Basic .NET. using Microsoft Visual Studio. NETMF features a subset
of the .NET base class libraries (about 70 classes with about 420 methods), an
implementation of Windows Communication Foundation (WCF) with
a GUI framework loosely based on Windows Presentation Foundation (WPF) and a
Web Services stack based on SOAP and WSDL. NETMF also features additional
libraries specific to embedded applications.

The .NET Micro Framework aims to make embedded development
easier, faster, and less expensive by giving embedded developers
access to the modern technologies and tools used by desktop
application developers. Additionally, it allows desktop .NET
developers to use their skills in the embedded world.

Why use .NET?
 Multilanguage Support
 Multi Application Support
 User friendly
 Easy to develop and deploy
 Easy to Learn
 Reduce line of code
 Provide better security of application

Framework contd….
 Framework is design pattern where we can develop
different type of application i.e. web, windows,
console, web service, user control etc. and deploy
these application.
 It has four compiler i.e. csc.exe, vbc.exe, jsc.exe,
vjsc.exe than another 56 language support with
interoperatibility
 It has two base component:
 Base Class Library(BCL) / Framework Class
Library(FCL)
 Common Language Runtime (CLR)

14

Base Class Library (BCL)
 The Base Class Library (BCL) is a standard library available
to all languages using the .NET Framework.
 Order to make the programmer's job easier, .NET includes the
BCL in order to encapsulate a large number of common
functions, such as file reading and writing, graphic rendering,
database interaction, and XML document manipulation.
 It is much larger in scope than standard libraries for most other
languages, including C++, and would be comparable in scope
to the standard libraries of Java.

15

Framework Class Library (FCL)
The .NET Framework Class Library (FCL) consists of a series of
classes, interfaces, and value types that can be used to program
with. The .NET Framework has types that allow one to easily:
1. Create effective graphical user interface applications
(System.Windows.Forms)
2. Access and manipulate data in various database formats
(System. Data and System.Xml)
3. Dynamically query type information (System. Reflection)
4. Perform basic Input/output operations (System.IO)
5. Perform operating system security checks (System.Security)
6. Create internet enabled applications (System.Net and
System.Net.Sockets)
7. Create dynamic web based applications – also known as
ASP.NET (System. Web)
8. Access basic data types, event handlers, and exceptions
(System) 16

Difference between BCL and FCL in .NET?
BCL , FCL both are not same. The Base Class Library (BCL),
sometimes incorrectly referred to as the Framework Class Library
(FCL) (which is a superset including the Microsoft.* namespaces),
is a library of types available to all languages using the .NET
Framework.
The BCL provides classes which encapsulate a number of
common functions such as file reading and writing, graphic
rendering, database interaction, XML document manipulation.
FCL = All namespaces (entire framework).
BCL = Common namespaces (core framework).
FCL = BCL + everything else that ships as part of the .NET
Framework.
