- 4. © Prognoz Technologies Pvt. Ltd Microsoft introduced the .NET Framework to make applications more interoperable. Interoperability of applications means the ability of applications, developed in different languages, to be able to work together and exchange information with each other. The objective of .NET framework is to bring various programming languages and services together. .NET Framework

- 6. © Prognoz Technologies Pvt. Ltd The. NET Framework consists of all the technologies that help in creating and running applications that are: Robust: Applications those are strong. Scalable: Applications that can be extended. Distributed: Applications that runs on computers of different networks. The .NET offers a complete suite for developing and deploying applications. This suite consists of: .NET Products .NET Services .NET Framework .NET Framework (Contd.)
- 7. © Prognoz Technologies Pvt. Ltd The .Net framework is a revolutionary platform that helps you to write the following types of applications: – Windows applications – Web applications – Web services The .Net framework applications are multi-platform applications. The framework has been designed in such a way that it can be used with any of the following languages: C#, C++, Visual Basic, Jscript, COBOL, etc. All these languages can access the framework as well as communicate with each other. .NET Framework (Contd.)

- 10. © Prognoz Technologies Pvt. Ltd Common Language Runtime (CLR): Is the environment where all programs using .NET technologies are executed. Provides services such as code compilation, memory allocation, and garbage collection. Allows the execution of code across different platforms by translating code into Intermediate Language (IL). IL is a low level language that the CLR understands. IL is converted into machine language during execution by the Just-In-Time compiler. During JIT compilation, code is also checked for type safety.

- 12. © Prognoz Technologies Pvt. Ltd CLR consists of a set of common rules followed by all the languages of the .NET Framework. This set of rules is known as Common Language Specification (CLS). CLS enables an object or application to interact with the objects or applications of other languages. One of the specifications defined in CLS is Common Type System (CTS), which provides a type system that is common across all languages. CTS defines how data types are declared, used, and managed in the code at run time. Components of the .NET Framework (Contd.)

- 15. © Prognoz Technologies Pvt. Ltd Compilation is the process of creating an executable program from a source code. When you compile a program in .NET, the conversion of source code to machine language happens in two stages. In the first stage, the compiler translates code into an IL instead of machine language or assembly language. In the second stage the conversion of IL to machine language is done at run time by the JIT compiler. Components of the .NET Framework (Contd.)

- 17. © Prognoz Technologies Pvt. Ltd During execution, CLR performs the following tasks: Loading assemblies and identifying namespaces JIT compilation Garbage collection The code developed in .NET is called managed code. The CLR manages the compilation and execution of the managed code to ensure proper functioning of the code. An assembly contains IL and metadata that was generated during compilation. Instead of compiling the complete IL code, the JIT compiler compiles only the code that is required during execution. Components of the .NET Framework (Contd.)
- 18. © Prognoz Technologies Pvt. Ltd Components of the .NET Framework (Contd.) The .NET Framework Class Library: Works with any .NET language, such as VB.NET, VC++ .NET, and VC#. Provides classes that can be used in the code to accomplish a range of common programming tasks, such as string management, data collection, database connectivity, and file access. Comprises namespaces, which are contained within assemblies.
- 19. © Prognoz Technologies Pvt. Ltd Components of the .NET Framework (Contd.) Assembly .NET Framework Class Library Namespaces help you to create logical groups of related classes and interfaces, which can be used by any language targeting the .NET Framework and are stored in assemblies. Namespaces
