• Platform Independence• Language Independence• Information about all types used in source

• Optional part• Details of external resources if used


• Consist of Meta-information and CIL• Basic Building blocks of .NET Framework• Self Descriptive• Two Types

• Private • Public

• Information about assembly• Assembly name• Assembly Version• Security Key• References to other assemblies used

• Resources required to develop and execute the applications

• Typically includes a hardware architecture and a software framework

CLR

CLS works with the CTS to ensure language interoperabilityThe CLS is a set of minimum standards that all compilers targeting .NET must support.

GCCAS

CLSJIT CTS

FCL

Common Type System defines the setpredefined data types available in IL

• Compiles CIL to Machine code• compiles portion of code as it is called.

And cached

Code Access Security Applies the permission to code, based on source of code and other identities

• garbage collector manages the allocation and release of memory for your application.

• Reclaims unreferenced or dead objects and clears their memory.

• Common Language Infrastructure is an international standard that is the basis for creating execution and development environments in which languages and libraries work together seamlessly.

Set of common classes need in various types of applications. Typically classes in System namespace.

Set of classes to be used for database communication

Provides architecture, library and controls to develop desktop applications.

• Library of tested, reusable code that developers can use in own applications

• Consists of classes, interfaces, and structures, delegates etc.

• Categorized using Namespaces

Namespaces support the hierarchical organization of classes and prevent type name collisions

Provides architecture to develop web applications and web services. Subsets are• WebForms• XML WebServices

Entity Framework Dynamic Data

3.5sp12008

object-relational mapper that enables .NET developers to work with relational data using domain-specific objects. It eliminates the need for most of the data-access code that developers usually need to write.

ASP.NET Dynamic Data lets you create extensible data-driven Web applications by inferring at run time the appearance and behavior of data entities from the database schema and deriving UI behavior from it.

Parallel LINQ (PLINQ) is a parallel implementation of LINQ to Objects.

Task Parallel Library set APIs in the System.Threading and System.Threading.Tasks namespacesEfficiently use all the available processors

• powerful, patterns-based way to build dynamic websites

• enables a clean separation of concerns• gives full control over markup• Provides features that enable fast Test

Driven Development for creating sophisticated applications that use the latest web standards.The Portable Class Library project enables you to write and build managed assemblies that work on more than one .NET Framework platform.

4.52012

WebSocket establishes persistent connection between the client and the server and both parties can start sending data at any time.

• HTML5 offers new features (elements, attributes, event handlers, and APIs) for easier web application development and more sophisticated form handling.

• JQuery is powerful JavaScript library• CSS is used to control the style and layout of

Web pages. CSS3 is the latest standard for CSS

• A Windows Store app is a new type of app that is sold in the Windows Store and runs on Windows 8 devices.

• Microsoft Windows Metro is the clean, dynamic, and content-focused UI in Windows 8.

CLR Versions and SxS Execution

Side By Side Execution Allows multiple versions of the Framework to be installed on a single system

4.0 onwards Supports inproc SxS

2002 20052003 2010 2012

• In-process side by side is the ability to run multiple versions of the CLR in a single process.• By default, managed COM components run with the .NET Framework version they were built with,

regardless of the .NET Framework version that is loaded for the process.


The .NET Framework is

an execution and

development

platform for building

apps for Windows,

Windows Phone,

Windows Server, and

Windows Azure... www.dotnetvideotutorial.com
