.Net Framework

.Net framework is a code execution platformthe

environment which .Net programs run.

.Net is a platform that provides a standardized set

of services. Its just like windows, except

distributed over the internet. It exports a commoninterface so that its programs can be run on any

system that support .NET. A specific software

framework includes a common runtime.

.Net framework mainly two components.

CLR

Classlibrary


4/15

CLR

Common language runtime is that when ever you can

create any application that application will build that

time .Net source code will be converted into MSIL code

that code will converted into machine language by using

JIT compliers.

The following are the components of CLR

Class loaderCompiler(jit)

Garbage collector

Security engine

Code manager

Type checker

Thread supportException manager

Debug engine

COM support the above functionalities achieved by

all these components .Each component is responsible

for specific functionality.

Class library

The .NET framework includes a set of standard class

libraries. The class library is organized in a hierarchyof namespaces. Most of the built in application are part

of either system.* Or microsoft.* Namespaces. These

class libraries implement a large number of common

functions, such as file reading and writing, graphic

rendering, database interaction, and XML documentmanipulation, among others. The .NET class libraries are

available to all .NET languages.

The .Net framework class library is divided into two

parts

Base class library

Framework class library

Difference

asp. Net 2.0 has added a number of special directories where 1.1

had only the one required bin directory.

Compilation model with 1.1, all code was compiled into one

assembly placed in the bin directory. With 2.0, the assembly is

separated into multiple assemblies. These multiple assemblies may be

created on-the-fly or precompiled.

The new generation of 64-bit computers enables the creation of

applications that can run faster and take advantage of more memory

than is available to 32-bit applications.

This feature provides new support for loading and activatingapplications through the use of a manifest.

The Microsoft. Net framework 2.0 includes significant enhancements

to all areas of ASP. Net. For web page development, new controls

make it easier to add commonly used functionality to dynamic webpages.

Features

.Net framework remoting

You can use .Net remoting to enable

communication between different application

regardless of whether they reside on same

computer or different computers. In addition,these computers can run on different operating

systems and still communicate with each other

using .Net remoting.


8/15

.Net framework remoting

.Net framework remoting now supports ipv6 addresses

and the exchange of generic types.

Obtaining information about local computer network

configuration and usage

Using classes in the system. Net. Network information

namespace, applications can access IP, ipv4, ipv6, TCP,

and UDP network traffic statistics.

Ping

The ping class allows an application to determine

whether a remote computer is accessible over the

network.Processing http requests from within applications

You can use the http listener class to create a simple

web server that responds to http requests.


9/15

Globalization

Globalization is the process of creating an

application that meets the needs of users frommultiple cultures. This process involves more

than just translating the user interface

elements of an application into multiple

languages and also includes using the correctcurrency, date and time format , calendar,

writing direction sorting rules ,and other

issues.


10/15

Manifest-Based Activation

This feature provides new support for loading and

activating applications through the use of a manifest.

Manifest-based activation is essential for

supporting click once applications.

Applications are activated through a reference

to an assembly that contains the application's entrypoint.

For example, clicking an application's .Exe file

from within the windows shell causes the shell to load

the common language runtime (clr) and call a well-known entry point within that .Exe file's assembly.

The assembly manifest contains assembly

metadata. Assembly manifest can be stored in either a

PE file(.Exe or .Dll file).


11/15

New Window-Based Form Control

The datagridview control provides a powerful and flexible way to

display data in a tabular format.

Toolstrip controls are toolbars that can host menus, controls, and

user controls in your windows forms applications. The toolstrip class

and its associated classes enable you to create toolbars and other

user interface elements in a style that is consistent with microsoft

windows XP, microsoft office, and microsoft internet explorer.

The maskedtextbox control uses a mask definition to distinguish

between valid and invalid user input.

The windows forms soundplayer class enables you to easily includesounds in your applications. The soundplayer class can play sound

files in the .Wav format, either from a resource or from universal

naming conventions (UNC) or HTTP locations. Additionally, the

soundplayer class enables you to load or play sounds asynchronously.


12/15

The windows forms splitcontainer control can be thought of as a

composite; it is two panels separated by a movable bar. When the

mouse pointer hovers over the bar, the cursor changes to show that

the bar is movable.

The listview control now supports three features provided by

windows xp and the windows server 2003 family: tile view, grouping,

and drag-and-drop item repositioning.

The listview, treeview, and tooltip controls now support ownerdrawing functionality similar to the owner drawing support for the

combobox, listbox, menuitem, and tabcontrol controls in the previous

release.

The webbrowser control lets you host web pages in your windows

forms applications. You can use the webbrowser control to provide

integrated html-based help or internet web browsing capabilities in

your application.


13/15

The flowlayoutpanel control arranges its

contents in a horizontal or vertical flow direction.

The tablelayoutpanel control arranges its

contents in a grid. Because the layout is

performed both at design time and run time, it can

change dynamically as the applicationenvironment changes.

The backgroundworker component

enables you to perform operations in thebackground that can take a long time to execute,

such as image downloads and database

transactions.

Conclusion

The .Net framework is nothing but you

can build a dynamic applications,

With this I am concluding my topic here. I

think I was able to give you an insight to

almost all main areas in .NET framework 2.0.
