Installation of .NET 6 has been included in the latest releases of DataMiner (10.3.3 and above). The DataMiner requirements suggest running the latest version of .NET, but the version requirements for newer DataMiner releases are vague.
Do the latest versions of DataMiner require both .NET 5 and 6? Or, can 5 be safely removed as it has reached EOL according to Microsoft?
.NET 5 has been removed and replaced with .NET 6 since DataMiner 10.3.9, see the dataminer change log: General Feature Release 10.3.9 | DataMiner Docs. Note an upgrade won't uninstall .NET 5 as it could be used/installed by other software on your server.
Also the DxMs have been upgraded to .NET 6 as you can see in the change log here: https://aka.dataminer.services/dataminer-services-change-log.
.NET 6 is included since DataMiner 10.3.3 but .NET 5 was also still required/included until 10.3.9, see https://docs.dataminer.services/release-notes/General/General_Feature_Release_10.3/General_Feature_Release_10.3.3.html#dataminer-upgrade-installation-of-microsoft-net-60-id_35363
Is .Net 3.5 still required for 10.2 and newer? I still see the System Display log in the 10.2 installer but afaik System Display is no longer supported in 10.2.
