No, the service packs for .Net are totally independent of the service packs for Vista. And they are unrelated to the service packs of MS Office also (just in case that would be your next question).

I am in the midst of refurbishing my kid's Dell laptop. I
have reinstalled Windows Vista <span style="mso-spacerun:yes"> version
6.0 and a bunch of updates. I know that I should have Service Pack 2 installed
and that I need have Service Pack 1 installed before I install SP2. <span style="mso-spacerun:yes">
When I check the system properties of my computer it lists Windows
Vista Home Premium in the "Windows Edition" section, but there is, for reasons
unknown, no mention of any service packs. But when I look in the update history
of Windows Update, it says I have installed Microsoft .NET Framework 2.0
Service Pack 2 Security Update for Windows Vista (KB974467), <span style="mso-spacerun:yes"> Update to .NET Framework 3.5 Service Pack 1
for the .NET Framework Assistant 1.0 x86 (KB963707), and Microsoft .NET
Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update (KB951847)
x86. Do I correctly read this to say that SP1 is installed but that I need to
now install SP2? Thanks.
