Download .NET Framework SP1 from:
http://www.microsoft.com/downloads/details.aspx?FamilyID=a8f5654f-088e-40b2-bbdb-a83353618b38&DisplayLang=en
Or if you have Windows Server 2003:

I thought this would be a "minor" update, addressing obscure issues... then I made the mistake of reading what's fixed in this Service Pack:
http://msdn.microsoft.com/netframework/downloads/updates/sptechpreview/content11sp1.aspx
If you care about "minor" things like "slow performance," "high memory conditions," and "memory leaks," you might want to install this Service Pack ![]()

now that is a service pack I thought 1.1 was nothing but a distant memory to msdn.

Oh, and for those of you who weren't paying attention to this a couple of days ago, it's been posted as a Critical Update to Windows Update

Shawn Farkas mentions the security-related fixes, but I think there are some worthwhile performance-related fixes in there too

Oh joy! It fixes the problem where forms draw really slowly when you set a minimum/maximum size on them.

Weird, my autoupdate didn't download it. I had to visit WindowsUpdate and there it was (as a critical) while my autoupdate was active.Karim wrote:Oh, and for those of you who weren't paying attention to this a couple of days ago, it's been posted as a Critical Update to Windows Update

Everybody seems to be having that particular trouble right now. For some reason this update isn't being offered through AU. I hope that's only temporary. -
Have you received a System.Reflection.TargetInvocationException by simply attempting to run the .NET 1.1 SP 1 installation?
I received the following error from the JIT:
"An Exception 'System.Reflection.TargetInvocationException' has occurred in SL35.tmp"
Thoughts? And yes, I have installed XP SP2 Successfully.

How long should this take? It has been at this stage for over an hour with no bars showing on the progress meter.
