Dotnet (stylized as .NET) is a modern, open-source, cross-platform development framework created by Microsoft that empowers developers to build a wide range of applications, from cloud-native APIs and web services to desktop software, mobile apps, and IoT solutions. At the heart of Dotnet is the Common Language Runtime (CLR), a managed execution environment that handles memory allocation, garbage collection, and exception handling, allowing developers to write efficient, secure, and high-performing code without worrying about low-level system complexities.
Dotnet supports multiple programming languages, most notably C#, F#, and Visual Basic, and includes a powerful Base Class Library (BCL) packed with reusable components for networking, file I/O, cryptography, data access, and more. With the introduction of .NET 6, 7, and 8, Microsoft unified its ecosystem, bringing together .NET Framework, .NET Core, and Xamarin into a single, cohesive platform optimized for speed, scalability, and portability.
Whether you’re deploying to the cloud via Azure, building microservices with ASP.NET Core, or developing high-performance applications with Blazor and MAUI, Dotnet provides the flexibility, stability, and productivity modern developers need. Its integration with tools like Visual Studio and GitHub Copilot makes Dotnet a cornerstone for enterprise-grade software engineering and digital transformation in the modern era.
