About the Courses

.NET (pronounced dot net) is a software framework developed by Microsoft primarily for Windows operating system. It contains two main components – Framework Class Library (FCL) and Common Language Runtime (CLR). FCL includes large class library which supports many other programming language codes to be run on .NET. FCL provides functions and classes for user interface, data access, database connectivity, cryptography, web application development, numeric algorithms, and network communications. CLR is the software environment like Virtual machine where all the programs written are executed. CLR provides services such as security, memory management, and exception handling. .NET framework led to different versions of .NET, each one specially designed for other platforms like embedded devices, web browser plugins and mobile computing. .Net Micro framework for embedded devices, Silverlight as web browser plugin and Mono for cross-platform and mobile devices. Microsoft developed a special integrated developed environment (IDE) for .NET called Visual Studio.
