Earlier I wrote about the speed of .NET2.0 installation. On that same machine I just finished installing .NET2.0 from scratch, and then .NET3.0.
Turns out .NET3.0 is a little bigger than .NET2.0, it’s a 52MB download instead of .NET2.0’s 23MBs.
Install time is also a little slower:
.NET2.0 download + install time: 8 minutes
.NET3.0 download + install time: 26 minutes
This might make it hard to deploy commercial applications on Windows XP with .NET3.0.
