What is .NET? It is Microsoft's strategy for development and deployment of software.

Microsoft has fundamentally changed the way programs execute under Windows.

Preference is now for interpreted code rather than machine code.

Modified versions of C++ & VB; C# added.

The environment has been redesigned to take full advantage of network standards.

.NET Framework Base Class Libraries

Common Language Runtime

Common Language Runtime

Interprets a byte code: Microsoft Intermediate Language (IL).

Similar to Java Virtual Machine.Some features:

SecurityGarbage collectionException handling

Also supports unmanaged code: machine code.

Consists of set of common rules followed by all the languages of .net framework

Interoperability between objects and applications.

The classes that follow by the rules specified by CLS are termed as CLS compliant classes

CTS provides a type system that is common across all languages.

Language Neutrality

Runtime Class Library

Removes much of the need for language specific libraries like C++'s STL.

Examples of items found in the Runtime:Basic typesCollection classesInput/OutputGraphical user interface libraryAccess to traditional Windows facilities (COM,

ADO)

User and Program Interfaces

Windows Forms Web FormsConsole

Applications

Assembly

A logical collection of one or more exe and dll file containing an application’s code and resources

It contains Codes in MSIL Manifest

A metadata description of the code and resources

What are the areas of .NET?

• Define products implemented by Microsoft

• Define client devices that use these services

• Defines backbone for the applications to build on.

• Managing, deploying and orchestrating the Web Services.

• Microsoft provides a tool for building the .NET framework.

Code access security

• Most software comes from web.A user doesn’t know whether a Web code is safe or not.

• .NET allows an administrator to specify privileges that each managed code has.

• You can specify these privileges in three levelby modifying XML-based files Enterprise Machine User
