5. Microsoft .NET .NET initiative in 2000
New vision for using Internet and the web in development, engineering, distribution and use of software
Rather than using a single programming language, it permits developers to create .NET applications in any .NET compatible language
A comprehensive programming model for building any application from mobile to web to desktop
.NET Framework is the heart of Microsoft’s .NET strategy.

6. .NET Framework and Common Language Runtime (CLR)
.NET Framework executes application
Its details are found in Common Language Infrastructure (CLI)
CLI contains information about the storage of data types, objects and so on
CLR is the central part of .NET Framework – it executes of .NET programs
First, the program is compiled into Microsoft Intermediate Language (MSIL) and is placed in executable file.
Code converted in MSIL by other languages can be combined by CLR
Second, another compiler just-in-time compiler (JIT Compiler) in CLR translates the MSIL into machine-language code according to specific platform
.NET Framework makes the applications “platform independent”
