.NET (pronounced as “dot net”) is a software framework built on c# technology language and is developed by Microsoft and runs primarily on Microsoft Windows. .NET is a free, cross-platform, open-source developer platform for building many different types of applications.
The .NET framework can work with several programming languages such as C#, VB.NET, C++ and F#.
C# (pronounced “see-sharp”) is the actual coding language that we write inside of the .NET framework. C# is an object-oriented programming language, meaning it can increase productivity in the development process.
Combined with the extensive class libraries, common APIs, multi-language support, and the powerful tooling provided by the Visual Studio family, .NET is the most productive platform for developers.
