Recently, Microsoft issued multiple patches to .NET. The patches are in roll-ups and are applied to various popular versions of .NET as well as the new .NET 4.7.

But what if:

  1. a system does not have .NET 4.7 installed
  2. the .NET rollup patches (described above) are applied
  3. .NET 4.7 is later installed

When step #3 is eventually performed, will the patches previously applied in step #2 somehow be applied to .NET 4.7?

BTW from what I can tell, this is going to be the typical order of operations for many/most systems.

Please include the Windows version number to which your answer applies. Thanks.

  • So you're asking if the .NET 4.7 installer includes the patches for the previous versions? Which previous version(s)? .NET 3? Earlier versions of .NET 4? – music2myear Oct 17 '17 at 18:30
  • This is easy to try yourself: Install patch on non-4.7 PC, install 4.7, run Windows Update to see if patch is offered again. My guess is yes...what is there to patch if the program isn't installed to begin with? – Twisty Impersonator Oct 17 '17 at 18:38
  • @music2myear Not quite what I'm asking... the .NET 4.7 installer does not include patches to previous versions, to my knowledge. Separate from the installer, MS is offering a .NET patch rollups that apply to multiple 4.x versions. IOW, each patch rollup applies to all recent 4.x versions. – RockPaperLizard Oct 17 '17 at 19:55
  • There's no question mark in what you just typed. You made three statements and didn't ask anything in the clarification, so I can still only guess. Are you asking if any given roll-up installer will include patches for all .NET 4.x versions? – music2myear Oct 17 '17 at 21:16
  • Are you asking, effectively, if you can skip step 2 if you were planning to do step 3? Please think carefully about what you're asking, and then use the EDIT button to clarify your question. – music2myear Oct 17 '17 at 21:19
