It introduced generics, anonymous methods, and the System.Web improvements that powered early 2000s enterprise web applications. For 64-bit systems, this version allowed applications to address more than 4 GB of memory, making it essential for early 64-bit database clients, CAD viewers, and scientific computing tools.

Note for Modern Windows Users: On Windows 10 and Windows 11, .NET Framework 2.0 is bundled inside the package. You do not need a separate .NET 2.0 executable; instead, you enable the .NET 3.5 feature, which automatically installs versions 2.0, 3.0, and 3.5 simultaneously. Step-by-Step Installation Methods
