Microsoft started development on the .NET Framework in the late 1990s originally under the name of Next Generation Windows Services (NGWS). By late 2001 the first beta versions of .NET 1.0 were released. The first version of .NET Framework was released on 13 February 2002, bringing managed code to Windows NT 4.0, 98, 2000, ME and XP.
Newbies may want to know what .Net is before they ask how it can help their business. The .Net system is actually a software framework so you might have heard of other names for it such as .Net Framework instead. It runs on the Windows operating system of Microsoft but is unique because it is compatible with a range of different programming languages. This means that you can run .Net on any of those programming languages without worrying that the code will be rejected. Because .Net is Windows based, many new applications that are grounded on the Windows OS platform are compatible with the .Net Framework.you integrate Windows.Net Development into your business.
