Scott Hanselman, the studmuffin of the Microsoft world drops some knowledge and clears up some confusion about the size of the .NET Framework.

The .NET Framework is not really a 200+ meg download. From Scott’s site:

Which installer do I use?

Here’s the whole thing in a nutshell for Developers, ISVs, and Administrators.

• Offline Installer - One single file that can be run offline and can install the .NET Framework any system it’s run on. It’s complete, all platforms, installable offline.
• Online Installer - A 2.7 meg setup program that will detect what just the files you need, then go download between 10 and 60 megs.
  • NOTE: If you’re IT and inside an office, you’ll want to decide if you want everyone in the office downloading .NET separately, or if you just want download it once, and have them to run it off a network share. Check out the Deployment Guide for Administrators for ways to push it out via AD or SMS.

So how big is it the .NET Framework download, really?

It depends on what you’ve already got installed. Here’s some examples of my results using an XP SP2 machine.

Scott goes into much greater detail on his blog here. He’s also launched a section of his site called SmallestDotNet, it checks you browser’s “UserAgent” and figures out what version (if any) of the .NET Framework you have (or don’t have) installed, then calculated the total size if you chose to download the .NET Framework. Easy huh. The bummer is that it doesn’t work with FireFox.
