NET Framework (Dot Net Framework) is a software platform (software framework) developed by Microsoft in 2002, mainly for the operating system Microsoft Windows. Includes extensive libraries and also provides cross-compatibility (each language can use code written in other languages) of multiple programming languages. Programs written in the .NET Framework run in software environment(as opposed to hardware) known as the Common Language Runtime (CLR, common language runtime), which is virtual machine, which provides security, memory allocation, and exception handling. The class library and the CLR together make up the .NET Framework.
The .NET Framework Core Class Library gives you access to user interface, data exchange, database connectivity, cryptography, web application development, computational algorithms and network connections. Programmers create their applications by linking their own code with .NET Framework libraries as well as other libraries. The .NET Framework is intended to be used by most new applications that are developed.
