The document provides an introduction and overview of the .NET framework. It discusses that .NET is an initiative by Microsoft to integrate their products for the next generation internet. The .NET framework provides a common language runtime, base class library, and supports multiple programming languages. It allows developing networked and web applications and services in a simplified and unified manner across devices and platforms.

1. INTRODUCTION TO .NET FRAMEWORK RAJESH GUNUKULA BY

3. What is Microsoft .NET? .NET represents an advanced new generation of software that will drive the Next Generation Internet. Its purpose is to make information available any time, any place, and on any device. Quick Definition .NET is an initiative to integrate all Microsoft products with the “Next Generation” web.

5. . NET Framework Programming model for .NET Platform for running .NET managed code in a virtual machine Provides a very good environment to develop networked applications and Web Services Provides programming API and unified language-independent development framework

6. .NET Framework Common Language Runtime CLR manages code execution at runtime Memory management, thread management, etc. Operating System Common Language Runtime

7. .NET Framework Base Class Library Object-oriented collection of reusable types Collections, I/O, Strings, … Operating System Common Language Runtime .NET Framework (Base Class Library)

8. . NET Framework Data Access Layer Access relational databases Disconnected data model Work with XML Operating System Common Language Runtime .NET Framework (Base Class Library) ADO .NET and XML

13. Common Language Runtime Just In Time (JIT) COMPILER Exception Manager Thread Manager Security Manager Garbage Collector Class loader Code Manager

14. Compilation in .NET Code in VB.NET Code in C# Code in another .NET Language VB.NET compiler C# compiler Appropriate Compiler IL(Intermediate Language) code CLR just-in-time execution

15. Intermediate Language (IL) .NET languages are not compiled to machine code. They are compiled to an Intermediate Language (IL). CLR accepts the IL code and recompiles it to machine code. The recompilation is just-in-time (JIT) meaning it is done as soon as a function or subroutine is called. The JIT code stays in memory for subsequent calls. In cases where there is not enough memory it is discarded thus making JIT process interpretive .

16. Languages Languages provided by MS VB, C++, C#, J#, JScript Third-parties are building APL, COBOL, Pascal, Eiffel, Haskell, ML, Oberon, Perl, Python, Scheme, Smalltalk …

17. Summary The .NET Framework Dramatically simplifies development and deployment Provides robust and secure execution environment Supports multiple programming languages
