History and Evolution

• Microsoft started development of .NET Framework
  in the late 1990s.
• At first Microsoft named .NET as Next Generation
  Windows Services (NGWS).
• First beta versions of .NET 1.0 were released in
  the end of 2002 and latest stable update released
  in 2016.
• Microsoft, Hewlett-Packard, and Intel worked to
  standardize Common Language Infrastructure (CLI)
  and C.
• .NET Framework is intended to be used by most new
  applications created for the Windows platform
• .NET Framework introduces a Common Type
  System (CTS) that defines all possible data
  types and programming constructs

What is .Net?

• .Net is a new framework for developing web based
  and windows based applications within the
  Microsoft environment.
• The Framework offers a fundamental shift in
  Microsoft strategy it moves application
  development from client centric to server centric.

Features of Dot Net

• Language Interoperability  Code written in any
  language can be used by other languages and there
  is an access provided to COM components in the
  System.
• Portable  .NET environment allow different
  devices, softwares and applications to work
  together across a wide and dispersed network of
  networks.
• Type Safety During program execution, the type
  checker ensures that all objects and values, and
  the references to those objects and values, have
  a valid type.
• Parallel Computing  .NET Framework introduces a
  model for writing multithreaded and asynchronous
  code that greatly simplifies the work of
  application and library developers.

• Automatic memory management ..NET takes away
  developers worry away by handling memory on its
  own and developer doesnt need to keep a check on
  it . 
•  Security Microsoft has taken great efforts to
  make .NET platform safe and secure for enterprise
  applications.
• Common Type System This provides the necessary
  data types, values, and object types, which you
  need to develop applications in different
  languages
• Dynamic Language Runtime The dynamic language
  runtime is a new runtime environment that adds a
  set of services for dynamic languages to the
  Common Language Runtime.

Dot Net Architecture

Architecture Components

• .NET Introduction Architecture components.NET
  framework contains four components. In thatfour
  components CLR and FCL are major
• 1.Common Language Runtime (CLR)
• 2.Framework Class Libraries (FCL).
• 3. Common Type System (CTS)
• 4. Common Language Specification (CLS)

9
Architecture Components

• Language Runtime(CLR) .NET Framework provides
  runtime environment called Common Language
  Runtime (CLR).It provides an environment to run
  all the .NET Programs. The code which runs under
  the CLR is called as Managed Code. 
• .Net Framework Class Library (FCL) The .NET
  Framework class library is a library of classes,
  interfaces, and value types that provide access
  to system functionality.
• Common Type System (CTS) It describes set of
  data types that can be used in different .Net
  languages in common .i.e. CTS ensures that
  objects written in different .Net languages can
  interact with each other.
• Common Language Specification (CLS) It
  specifies a set of rules that needs to be adhered
  or satisfied by all language compilers targeting
  CLR. It helps in cross language inheritance and
  cross language debugging.

Advantages

• It is very user friendly 
• Interoperable i.e. each language can use code
  written in other languages
•  Enhanced Security, Easy Portability
• Gives stable support to  XML, cascading style
  sheets (CSS), and other new and established Web
  standards
• Permits a wide variety of Internet devices to
  access data and applications 
• Easy integration of any software into the
  Internet
• Ability to track visitors and report on the most
  requested web pages

11
Conclusion

• The .NET Framework is an open-source developer
  platform you can use to create a broad range of
  applications.
• Dramatically simplifies development and
  deployment.
• Provides robust and secure execution environment
• Supports multiple programming languages
