.NET is an integral part of many applications running on Windows and provides common functionality for those applications to run. This download is for people who need .NET to run an application on their computer. .Net provides a common platform for developers to target services that run on-premise or in the cloud. Its close integration with Windows Server and Windows Azure allows applications to be gradually extended to the cloud, taking the most of each platform and enabling hybrid applications that sit between the two worlds.
.NET provides a consistent, first-class development experience across all Microsoft devices.
