How do I slipstream the .NET 2.0 (or .NET 3.5 for that matter) framework into an nLite Windows XP SP3 ISO?
Well, I would start by reviewing the runonce explanation Here. After that, copy your .net binaries to the root of the cd before creating the ISO. After that, add the runonce commands found Here to the runonce section under the unattended tab (ensuring that they are tailored for your setup, ie the paths are right in the commands). That should work for you. Good Luck.
