Why does the Microsoft .NET Framework 2.0 require 280MB of space to install?


…When the download is only ~28MB



The Microsoft download site has the following prerequisite info for the download and install:



System Requirements

  • Supported Operating Systems: Windows 2000 Service Pack 3; Windows 98; Windows 98 Second Edition; Windows ME; Windows Server 2003; Windows XP Service Pack 2
  • Disk Space Requirements: 280 MB (x86), 610 MB (x64)

Actually, the interesting thing is that on install you are only required to have a minimum of 130MB to install the Framework

(Here’s the link to see for yourself:



Suspected Reasoning:


Couple of things might be behind the 280MB. One is that Microsoft installs the framework in 2 places, plus they install a couple of directory structures. All of that is expanded out of the 28MB download.


If you look, the 1.1 size was 70MB under C:\windows\Microsoft.Net\Framework\v1.1.4322. Throw in the 50+MB under C\Windows\Assemblies (the 2nd copy), and then recognize that 2.0 is about double the size content-wise, and I think it makes sense.


Notice in the screenshot, the different sizes of the C:\Windows\Microsoft.NET\Framework\ dir




It does seem big, I agree. But it’s kind of an investment going forward. In 5 years it won’t be an issue. I’m sure Microsoft knows this doesn’t really help today, but they’re in a bit of a transition phase with this, and the 280MB is just one of the bumps in the road.
