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.

Common Language Runtime Interprets a byte code: Microsoft Intermediate Language (IL). Similar to Java Virtual Machine. Some features: Security Garbage collection Exception handling Also supports unmanaged code: machine code.

Common Language Specification 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.

Runtime Class Library Removes much of the need for language specific libraries like C++'s STL. Examples of items found in the Runtime: Basic types Collection classes Input/Output Graphical user interface library Access to traditional Windows facilities (COM, ADO)

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 level by modifying XML-based files Enterprise Machine User
