.NET framework is a software framework used to help developers create applications easily because it includes numerous codes that can be called without a need to write them at first. Since 2002, the .NET framework technicians have release 7 versions and the latest one is .NET framework 4.5. Each version should be integrated with a certain Windows Server. For example, the .NET framework 3.0 is distributed to Windows Server 2008 while the 3.5 edition is for Windows Server 2008R2.
This framework creates an object-oriented programming environment as well as minimizes conflicts among different versions and software deployment. And also, it is an effective method to improve the security of code execution, no matter who create the code, even for the unknown third parties. With this rich-featured framework, developers are able to develop a wide range of applications whether they are Windows-based or Web-based.
In addition, the .NET framework comes with several design features, including Interoperability, Language Independence, Common Language Runtime engine, Framework Class Library, Security, and Simplified deployment. Each has its own strong points. Take the Framework Class Library as an example. It is full of functionalities, such as database interaction, reading & writing, XML document manipulation, and so on, available for all languages using .NET framework.
