What is .Net framework?
.Net framework is a software development platform
designed by Microsoft. The framework was meant to
create applications, which would run on the
Windows Platform. The first version of the .Net
framework was released in the year 2000. The
version was Named .Net framework 1.0. The .Net
framework has travelled a lot way since then, and
the latest version is 4.6.1. The .Net framework
can be used to create both  windows
based and Web based applications. Web
services can also be enhanced using the .Net
framework.

.NET Framework Objective

• Create a environment for Object Oriented
  Programming.
• 2. To create for environment for making Form
  based application and web based application .
• 3. To see to it that coding of .net framework
  should integrate with every other code

.NET Framework
Base Class Library
5
.NET Framework contains The Common Language
Specification (CLS) It contains set of rules,
that language should follow so that they can
contact with other .NET languages. It is also
leads for Type matching. The Framework Base
Class Libraries (BCL)A persistent,
object-oriented library of prepacked
functionality and Applications. The Common
Language Runtime (CLR) A language-neutral
development execution environment that provides
common runtime for application run .

• CLS performs the following functions
• Establishes a framework that helps enable
  cross-language integration, type safety, and high
  performance code execution
• 2. Provides an object-oriented model that
  supports the complete implementation of many
  programming languages
• 3. Defines rules that languages must follow,
  which helps ensure that objects written in
  different languages can interact with each other

.NET Framework Base Class Library

• The Class Library is a comprehensive,
  object-oriented collection of reusable types
• These class library can be used to develop
  applications that include
• Traditional command-line applications
• Graphical user interface (GUI) applications
• Applications based on the latest innovations
  provided by ASP.NET
• Web Forms
• XML Web services

Common Language Runtime (CLR)
CLR 1. Common runtime environment for all .NET
languages 2. Use Common Type System 3. Memory
allocation and Bin collection 4. Intermediate
Language to local code compiler. Which Compiles
MSIL code into local executable code 5. Security
and inner compilation of the code with other
languages There are over 36 language which are
supported here are few 1. C, VB, Jscript,
Visual C from Microsoft 2. Perl, Python,
Smalltalk, Cobol, Haskell, Mercury, Eiffel,
Oberon, Oz, Pascal, APL, CAML, Scheme, etc.
