The.NET Framework (pronounced as " dot net ") is a proprietary software framework developed by Microsoft that runs primarily on Microsoft Windows. It was the predominant implementation of the Common Language Infrastructure (CLI) until being superseded by the cross-platform.NET project.

.NET Framework is a technology that supports building and running Windows apps and web services.. NET Framework is designed to fulfill the following objectives: Provide a consistent, object-oriented programming environment whether object code is stored and executed locally, executed locally but web-distributed, or executed remotely.

.NET is a developer platform made up of tools, programming languages, and libraries for building many different types of applications. There are various implementations of.NET. Each implementation allows.NET code to execute in different places—Linux, macOS, Windows, iOS, Android, and many more.

.NET Framework is a run-time execution environment that manages apps that target.NET Framework. It consists of the common language runtime, which provides memory management and other system services, and an extensive class library, which enables programmers to take advantage of robust, reliable code for all major areas of app development.

On Windows 11 (and 10), the ".NET Framework" ("dot net") is a development platform made up of programming languages, libraries, and tools for programmers to build different types of programs for desktops, laptops, tablets, servers, web apps, and games.
