WHAT IS .NET ?

NET is platform introduced byMicrosoft todevelop, deploy, host, maintainand execute

your application.

In other words it caters to developmentphaseof software development life cycle of an

application making developer life morecomfortable..

.NET FRAMEWORK Definition: Is a collection of different

components, files, documents that arebundled together.

.NET Framework Architecture consist of

various components and each componentprovide specific functionality.


4/19

.NET FRAMEWORK ARCHITECTURE

Consist of5components and eachprovide specific functionality:

.Net Compliant Languages

Common Language Specification (CLS)

Framework Class Library (FCL)

Common Language Runtime (CLR)

Visual Studio IDE

.NET COMPLIANT LANGUAGE

It is the first component of .net architecture.

Is imperative feature of .net and is a facility toprogram in multiple languages, which allowsprogrammers to use their favorite language as itsupports 59 languages.

Examples: VB .Net, VC#, VJ#, VC++ and many more.

COMMON LANGUAGE SPECIFICATION

It is the second and important componentof .net architecture. CLS defines standard rules for defining

.NET Compliant Languages.

Ensure the source code complied by .NETcomplier interoperate with .NET

Framework. CLS include a subset of CTS (Common

Type System)


9/19

COMMON TYPE SYSTEM(CTS)

CTS defines rules regarding data types. All types are derived from a base class i.e.,

System.Object

Ensure typesafety, cross languageinteroperability, and high performance ofcode execution.

COMMON LANGUAGE RUNTIME

It is the fourth component or heartof .netframework architecture.

It is known as executionengineof .NETframework.

Services of CLR are: Secure code of execution(checks of code to see if

they follow all defined rules).

Automatic memory management(GC) Interoperability

Exception handling


14/19

EXECUTION CYCLE OF CLR

Language specific compiler


15/19

MSIL(Microsoft Intermediate

Language)

This is a intermediate language used to convertthe

source code to dotnet supportable code (otherwise

called assemblies or Portable Executable(PE) file)

during compilation. This PE file is machineindependent.


16/19

JIT-JUST IN TIME

The best features of the CLR is JIT-compilation.

Its name describes how it works: right beforecalling your method (just in time), the CLR

uses the JIT-compiler to produce native

code(EXE or DLL) that is designed for specific

machine from MSIL.
