Introduction to .NET

The .NET Framework (pronounced “dot net framework”) defines the environment thatyou use to execute Visual Basic .NE applications and the services you can use

within those applications. !ne of the main "oals of this framework is to make it easier to

develop applications that run over the #nternet. $owever% this framework can also &e used

to develop traditional &usiness applications that run on the 'indows desktop. o develop a

Visual Basic .NE application% you use a product called Visual tudio .NE

(pronounced “Visual tudio dot net”). his is actually a suite of products that includes

the three pro"rammin" lan"ua"es. Visual tudio also includes several other components

that make it an outstandin" development product. !ne of these is the icrosoft

*evelopment Environment% which you+ll &e introduced to in a moment. ,nother is the

icrosoft - erver /000 *esktop En"ine (or *E). *E is a data&ase en"ine

that runs on your own 12 so you can use Visual tudio for developin" data&ase applications

that are compati&le with icrosoft - erver. - erver in turn is a data&ase mana"ement

system that can &e used to provide the data for lar"e networks of users or for #nternet

applications. 1ro"rammin" lan"ua"es supported &y Visual tudio .NE an"ua"e

*escription Visual Basic .NE *esi"ned for rapid application development. Visual

23 .NE , new lan"ua"e that com&ines the features of 4ava and 255 and is suita&le

for rapid application development. Visual 255 .NE icrosoft+s version of 255 that can &e

used for developin" hi"h6performance applications. he .NE 7ramework provides a

common set of services that application pro"rams written in a .NE lan"ua"e such asVisual Basic .NE can use to run on various operatin" systems and hardware platforms.

The .NET Framework is...

8 , component model for the internet

8 he new approach to &uildin" lar"e scale distri&uted systems for the #nternet

8 1rovides the capa&ility to inte"rate multiple devices.

8 Built around the tools and protocols (9% '*% !,1% $1) that are &ecomin"

The .NET Framework is diided into two main com!onents"

8 he .NE 7ramework 2lass i&rary

8 he 2ommon an"ua"e :untime

The .NET Framework #lass $i%rar& consists of se"ments of pre6written code called

classes that provide many of the functions that you need for developin" .NE

applications. 7or instance% the 'indows 7orms classes are used for developin" 'indows

7orms applications. he ,1.NE classes are used for developin" 'e& 7orms

applications. ,nd other classes let you work with data&ases% mana"e security% access

files% and perform many other functions. ,lthou"h it+s not apparent in this fi"ure% the

classes in the .NE 7ramework 2lass i&rary are or"ani;ed in a hierarchical structure.

'ithin this structure% related classes are or"ani;ed into "roups called namespaces. Each

namespace contains the classes used to support a particular function. 7or example% the

ystem.'indows.7orms namespace contains the classes used to create forms and the

ystem.*ata namespace contains the classes you use to access data.

The #ommon $anguage 'untime( or #$'( provides the services that are needed for

executin" any application that+s developed with one of the .NE lan"ua"es. his is

possi&le &ecause all of the .NE lan"ua"es compile to a common intermediate lan"ua"e. he

2: also provides the 2ommon ype ystem that defines the data types that are used

&y all the .NE lan"ua"es. hat way% you can use more than one of the .NE

lan"ua"es as you develop a sin"le application without worryin" a&out incompati&le data

types.



The .NET Framework

Descri!tion" )

8 .NET a!!lications do not access the operatin" system or computer hardware directly.

#nstead% they use services of the .NE 7ramework% which in turn access the operatin"

system and hardware.

8 The .NET Framework consists of two main components< the .NE 7ramework 2lass

i&rary and the 2ommon an"ua"e :untime.

8 The .NET Framework #lass $i%rar& provides pre6written code in the form of classes that

are availa&le to all of the .NE pro"rammin" lan"ua"es. his class li&rary consists of hundreds of classes.

8 The #ommon $anguage 'untime *#$'+ is the foundation of the .NE 7ramework. #t

mana"es the execution of .NE pro"rams &y coordinatin" essential functions such as

memory mana"ement% code execution% security% and other services. Because .NE

applications are mana"ed &y the 2:% they are called mana"ed applications.

8 The #ommon T&!e S&stem *#TS+ is a component of the 2: that ensures that

all .NE applications use the same &asic data types re"ardless of what pro"rammin"

lan"ua"es were used to develop the applications.

A0ter the release o0 4nternet 4n0ormation Ser/ices >$' in &??2 Microso0t

began researching possibilities 0or a new web application moel that



woul sol/e common complaints about ASP2 especially with regar to

separation o0 presentation an content an being able to write @clean@

esign was e/elope o/er the course o0 two months by Aners an

uthrie2 an uthrie coe the initial prototypes uring the Christmas

holiays in &??$

originally name it$ The initial prototype o0 SP was one using 8a/a2 but it

was soon ecie to buil the new plat0orm on top o0 the Common

en/ironment2 garbage collection an other 0eatures that were seen as

esirable 0eatures that Microso0t;s Component <bject Moel plat0orm

success o0 their new web e/elopment plat0orm woul be tie to the

success o0 the C+"2 which2 li,e SP2 was still in the early stages o0

intention was to pro/ie an easy migration path 0or ASP e/elopers$

other web e/elopment technologies such as P3P2 8rSP2 an ASP$ 5ith

ASP$#et :ramewor, 9$'2 Microso0t introuce a new coe-behin moel

which allows static text to remain on the $aspx page2 while ynamic coeremains in the $asp$cs page$

Coe-behin moel

Microso0t recommens ealing with ynamic program coe by using the

coe-behin moel2 which places this coe in a separate 1le or in a

specially esignate script tag$ Coe-behin 1les typically ha/e names

li,e MyPage$aspx$cs or MyPage$aspx$/b while the page 1le is MyPage$aspx

(same 1lename as the page 1le (ASP!2 but with the 1nal extension

enoting the page language!$ This practice is automatic in Microso0t Iisual

Stuio an other 4*Es$ 5hen using this style o0 programming2 the

e/eloper writes coe to respon to ierent e/ents2 li,e the page being

loae2 or a control being clic,e2 rather than a proceural wal, through

the ocument$

ASP$#ET;s coe-behin moel mar,s a eparture 0rom Classic ASP in that

it encourages e/elopers to buil applications with separation o0

presentation an content in min$ 4n theory2 this woul allow a web

esigner2 0or example2 to 0ocus on the esign mar,up with less potential

0or isturbing the programming coe that ri/es it$ This is similar to the

separation o0 the controller 0rom the /iew in moel-/iew-controller

0ramewor,s$

*irecti/es

A irecti/e is special instructions on how ASP$#et shoul process the

page$The most common irecti/e is NO Page N which can speci0y

many things2 such as which programming language is use 0or the ser/er-

sie coe$



ser controls

Bser controls are encapsulations o0 sections o0 pages which are registere

an use as controls in ASP$#ET$ Bser controls are create as ASC

mar,up 1les$ These 1les usually contain static (!3TM+ mar,up2 as well as

mar,up e1ning ser/er-sie web controls$ These are the locations where

the e/eloper can place the re6uire static an ynamic content$ A user

control is compile when its containing page is re6ueste an is store in

memory 0or subse6uent re6uests$ Bser controls ha/e their own e/ents

which are hanle uring the li0e o0 ASP$#ET re6uests$ An e/ent bubbling

mechanism pro/ies the ability to pass an e/ent 1re by a user control up

to its containing page$ Bnli,e an ASP$#ET page2 a user control cannot be

re6ueste inepenentlyD one o0 its containing pages is re6ueste instea$

Custom controls

Programmers can also buil custom controls 0or ASP$#ET applications$

Bnli,e user controls2 these controls on;t ha/e an ASC mar,up 1le2

ha/ing all their coe compile into a ynamic lin, library (*++! 1le$ Such

custom controls can be use across multiple web applications an Iisual

Stuio projects (which is not allowe with user controls!$ 7y using a

"egister irecti/e2 the control is loae 0rom the *++$

"enering techni6ue

ASP$#ET uses a /isite composites renering techni6ue$ *uring

compilation2 the template ($aspx! 1le is compile into initialiHation coe

which buils a control tree (the composite! representing the original

template$ +iteral text goes into instances o0 the +iteral control class2 an

ser/er controls are represente by instances o0 a speci1c control class$

The initialiHation coe is combine with user-written coe (usually by the

assembly o0 multiple partial classes! an results in a class speci1c 0or the

page$ The page oubles as the root o0 the control tree$



Actual re6uests 0or the page are processe through a number o0 steps$

:irst2 uring the initialiHation steps2 an instance o0 the page class is

create an the initialiHation coe is execute$ This prouces the initial

control tree which is now typically manipulate by the methos o0 thepage in the 0ollowing steps$ As each noe in the tree is a control

represente as an instance o0 a class2 the coe may change the tree

structure as well as manipulate the propertiesQmethos o0 the ini/iual

noes$ :inally2 uring the renering step a /isitor is use to /isit e/ery

noe in the tree2 as,ing each noe to rener itsel0 using the methos o0

the /isitor$ The resulting 3TM+ output is sent to the client$

A0ter the re6uest has been processe2 the instance o0 the page class is

iscare an with it the entire control tree$ This is a source o0 con0usion

among no/ice ASP$#ET programmers who rely on class instance members

that are lost with e/ery page re6uestQresponse cycle$

PE":<"MA#CE

ASP$#ET aims 0or per0ormance bene1ts o/er other script-base

technologies (incluing Classic ASP! by compiling the ser/er-sie coe to

one or more *++ 1les on the web ser/er$ This compilation happens

automatically the 1rst time a page is re6ueste (which means the
