.NET Framework
.NET Framework is a proprietary software framework developed by Microsoft that runs primarily on Windows. It provides a large class library called Framework Class Library (FCL) and language interoperability across several programming languages, enabling developers to build a wide range of applications, including desktop, web, and mobile. It includes features like memory management, security, and exception handling, and supports languages such as C#, VB.NET, and F#.
Developers should learn .NET Framework for building Windows-specific applications, particularly legacy enterprise systems, desktop apps using Windows Forms or WPF, and ASP.NET web applications. It is essential for maintaining and modernizing existing .NET-based codebases in corporate environments, and offers robust tools and libraries for secure, scalable solutions on Windows servers. Use cases include internal business applications, government systems, and industries where Windows infrastructure is mandated.
