.NET is a development framework created by Microsoft that allows programming in multiple languages. It includes a large class library called Framework Class Library (FCL) and provides language interoperability across different platforms. Developers can use Visual Studio which is an IDE that makes building .NET applications easier. There is a high demand for .NET developers due to a shortage of trained professionals and jobs in .NET are doubling every year.
