The .NET Framework is a programming model that supports building and running of software applications for Windows, Windows Server, Windows Phone, Microsoft Azure, and XML Web services. It is developed by Microsoft and runs on Microsoft Windows. The .NET Framework consists of a large class library known as Framework Class Library (FCL), and Common Language Runtime (CLR) which provides language interoperability across several programming languages. This framework was written to overcome many of the problems of application development including long development times, inability to change applications quickly, high total cost of ownership of software and ease of deployment. It is a comprehensive and consistent programming model for building applications that have visually stunning user experiences, seamless and secure communication, and the ability to model a range of business processes. Benefits of .Net: Less Coding and Increased Reuse of Code This framework works on object-oriented programming which eliminates unnecessary codes and involves less coding for the developers. .NET consists of re-useable code and many re-useable components. That’s why it takes less time and consequently costs less to develop applications. Deployment The code execution environment supports safe code execution for reduced conflicts in software deployment and versioning, and minimized performance problems of scripted or interpreted environments. Reliability Since its release in 2002, .NET has been used to develop thousands of applications. Its performance on Microsoft® Windows Server™ 2003 and Windows 2000 Server is also very stable and reliable. Security .NET offers enhanced application security as web applications developed using ASP. NET have Windows confirmation and configuration. Managed code and CLR offer safeguard features such as role-based security and code access security. Use across Platforms and Languages .NET allows developers to develop applications for a desktop, a browser, a mobile browser, or an application running on PDA. .NET is promoted as a language-independent framework, which implies that development can take place in different compliant languages that include C#, managed C++, VB.NET, Visual COBOL, IronPython, IronRuby and more. Use for Service-Oriented Architecture .NET is often used for Web Services, which are a solution for executing an SOA strategy. Through Web Services, applications which are designed in different programming languages or platforms, are able to communicate and transmit data utilizing standard Internet protocols. Integration with Legacy Systems The capability of .NET to process all types of XML documents and write any format of file with swiftness and ease, provides multiple routes for integration. .NET is a great platform for businesses, as it enables them to easily integrate systems and information, making collaboration and communication more effective. It is a secure and efficient platform that offers many benefits, including rapid development, less maintenance, lower costs, and increased return on investment.
