Last beta for .NET v4.5.2?

Anyone happen to know what was last beta release to support .NET v4.5.2?

Anything before canary 2.0.4.24 targets 4.5, so that would be beta 2.0.4.23 from 2019. You should probably look at fixed issues since then before you actually try to use it, there were some corruption bugs from what I could tell.

2.0.4.23_beta_2019-07-14

Changes in this version:
This update only contains warnings to inform users on Amazon Cloud Drive that the service is discontinued.

meaning besides that, it’s:

2.0.4.5_beta_2018-11-28

so it’s missing lots of fixes.

2.0.5.1_beta_2020-01-18 is a bit better but needs .NET Framework 4.6.2 which goes back to Windows versions such as 7 and Server 2008 which lost their Microsoft support January 2020. What are you on?

I think that .NET 4.5.2 was last supported on Windows Vista (remember it ?)

.NET Framework 4.5.2 shows its non-server range from Vista through 8.1.
although Microsoft .NET Framework shows that support ended April 2022.
.NET Framework 4.6.2 is 7 through 10 Anniversary Update (Version 1607)

Well yes but the true problem is the reverse one, which OS was last supporting 4.5.2 but not higher versions. With Windows 7 last SP, current Duplicati could be installed (theoretically at least).

2.0.4.23_beta_2019-07-14

Thank you.

What OS are you on?, Are you the sysadmin and willing to update .NET Framework (if possible)?

Thank you too.

Prefer not to provide answer due to opsec.

Fixes in 2.0.5:

  • Fix backup corruption from upload throttling. #3787
  • Fix for “Unexpected difference in fileset”. #3800
  • Fix for “CheckingErrorsForIssue1400” and “FoundIssue1400Error”. #3868
  • Fix for “FTP (Alternative)” upload verification.

Especially #3868 seems pretty dangerous (it breaks the backup if files increase in size while they are read, from what I understood from this comment). So I would strongly suggest you look for a different option.

3800 breaks the backup all by itself, but both those issue are data or activity related, so not all hit them.
Basic idea though is that older Duplicati versions work worse in various ways. Newer is usually better…

Microsoft’s current page doesn’t go way back into history, but some (disagreeing) clues on history are at

What is latest Duplicate beta that support .NET 4.6.2?

Seems [v2.0.5.1-2.0.5.1_beta_2020-01-18] (Release v2.0.5.1-2.0.5.1_beta_2020-01-18 · duplicati/duplicati · GitHub)

Agree on 2.0.5.1 for .NET Framework 4.6.2. 2.0.6.3 wants .NET Framework 4.7.1.
