C1 V9 and NET 4.6

Hi,

together with the V9 upgrade there was an update to a new version of NET.

Now I've noticed that I have different older versions of NET on my machine and I've also noticed that from time to time they get updates.

I'm aware that this isn't a question related properly to V9 or Phase One's software but is here someone who could enlighten me about:
1) What are those older versions of NET good for?
2) Does the new version 4.6 include all previously available functionality so older version could just be de-installed?
3) Or might older SW require older versions of NET and they wouldn't run with 4.6?

I thought this might be of broader interest if possibly not necessary NET version could be de-installed.

Thanks in advance for your input.

  Hi Michael,
  
  Answers can be the following :
  
  1) They can be good for former software you may have still installed and running on your PC
  2) Normally yes, but the former software may call functions, but those may behave slightly differently, thus be cautious
  3) They shall run but there is a chance their behavior might be changed, depending on how the developer made the call to .net functions
  
  Conclusion :
  - If in real need of place on you HDD you may try to remove the former .net stuff, and then run your former application in order to check what happens, if some are claiming for former .net you will have then to reinstall them. All depends on how much software you do have running on your PC.

  Hi,
  
  thanks for the input.
  
  It's not so much about space on the HD but as with other apps, doubled functionality in combination with superseeded version is not recommended to keep in certain cases (thinking of java, for example) for several reasons, including security.
  
  To some point it is a bit clearer now to me that there's "something different" among the NET versions because why MS would bother to come out with updates for older versions if they would be totally substituted by the newer ones. So I won't bother anymore for now. Thanks again.

  Michael,
  
  Although MS may have provided backwards compatibility in later version of .NET (note the MAY) there is no certainty that developers have made the effort to follow them and of course older software will not be aware of the new versions without some re-pointing in the settings.
  
  Of course the concept moves on once all software has gone to subscription mode and old version will no longer be required/supported .... 🤬
  
  I have been told that MS is still providing security related updates to .net3 late version(s) but not .net4 early versions. My product developer friend found this interesting but was not sure of the reasoning behind it when he mentioned it. It makes some of their prior generation product releases cast off from security support when earlier and later products are still being brought up to date. Potentially a rather odd situation to discuss with clients.
