Evolution of .NET Frame work

          Microsoft .Net technology has a rapid development and great success over the years. This is one of the best development platforms and accepted by all levels of peoples. The features like interoperability, security, portability, simplicity and maintainability makes the .NET technology as great. The .Net framework created on the year 2002 and still the features added and various versions of framework released for advanced software development.

What is .Net Framework?

          The .NET Framework is an integral Windows component that supports building and running the next generation of applications and XML Web services. The .NET Framework is designed to fulfill the following objectives:
  • To provide a consistent object-oriented programming environment whether object code is stored and executed locally, executed locally but Internet-distributed, or executed remotely.
  • To provide a code-execution environment that minimizes software deployment and versioning conflicts.
  • To provide a code-execution environment that promotes safe execution of code, including code created by an unknown or semi-trusted third party.
  • To provide a code-execution environment that eliminates the performance problems of scripted or interpreted environments.
  • To make the developer experience consistent across widely varying types of applications, such as Windows-based applications and Web-based applications.
  • To build all communication on industry standards to ensure that code based on the .NET Framework can integrate with any other code.
