The new list for .NET Framework 1.1 (2011-05-13)
NDP1.1sp1-KB971108-X86.exe - W2K only
NDP1.1sp1-KB2416447-X86.exe (supersedes KB979906)
The new list for .NET Framework 2.0 (2011-05-13)
NDP20SP2-KB971111-x86.exe - W2K only
NDP20SP2-KB2418241-x86.exe (supersedes KB976765)
NDP20SP2-KB2446704-v2-x86.exe (supersedes KB983583, KB976569, KB974417)
All of them can be processed by SNMsynth but in case of KB2446704-v2 you may have to remove the "-v2" as the filename is too long and results in a "file not found" error.
As I'm using Windows 2000 I'm not really interested in making a current list of .NET 3.5 updates. Still it would be nice if someone else made an updated list for newer Frameworks
Why is NDP20SP2-KB976576-x86.exe downloading as ndp20sp2-kb976576-x86_8e8121a8bddfb2095453335c593ffa22ef8e95ec.exe? And when I Google for it, I get what I think is strange. I get pages coming up in different languages, no pages linking to Microsoft about the update.
