Microsoft's.NET framework is a software development framework. It gives developers a programming model and a set of libraries to use for creating Windows desktop apps, online applications, and web services that can operate on Windows, macOS, and Linux. .NET incorporates several programming languages, including C#, F#, and Visual Basic, and allows developers to construct applications with a variety of tools, including Visual Studio and Visual Studio Code. The Common Language Runtime (CLR) is a major element of.NET that offers a managed execution environment for.NET programs. The CLR manages memory, security, and exception handling, allowing developers to concentrate on creating application code.
