.NET Framework 3.5 is a software framework developed by Microsoft that is used to build and run applications on Windows operating systems. It includes a large library of pre-built code and tools that developers can use to create applications for desktop, web, and mobile devices. Some of the key features of .NET Framework 3.5 include support for web services, improved security, and improved performance.
