Wow, more clueless people.

It's not necessary to have it installed, nope. Your machine will function perfectly well without it.

it is, and i'm quoting from microsoft here:

".NET is the Microsoft Web services strategy to connect information, people, systems, and devices through software. Integrated across the Microsoft platform, .NET technology provides the ability to quickly build, deploy, manage, and use connected, security-enhanced solutions with Web services. .NET-connected solutions enable businesses to integrate their systems more rapidly and in a more agile manner and help them realize the promise of information anytime, anywhere, on any device."

It's not entirely unlike Java in that it has prewritten components that can be reused to save programmers from writing their own code to do certain things.

You'd need the framework installed if you plan on using software that's been built using .NET.
