Hi

I am working on a legacy application and need to find updates for .NET 4.5.x (i.e. 4.5, 4.5.1 and 4.5.2) for Win 10 IoT Enterprise 2019 LTSC.

Kind regards

    An up-to-date Windows 10 system will have .net framework 4.8 installed. I'll guess that's the reason that updates for lower versions of the framework are not offered for Windows 10.

    Hi @RLWA32

    Thanks for your response. As per your comment quote "An up-to-date Windows 10 system will have .net framework 4.8 installed. I'll guess that's the reason that updates for lower versions of the framework are not offered for Windows 10", if that is the case, why then do we have Win 10 update for .NET 3.5?

    Many thanks

    You have a couple issues.

    1) you can not install a lower version of .net 4.* once a higher version is installed
    2) after windows 10 (1507) .net 4.6 + was included with the o/s

    This means you need to start with an older version of windows 10 (<1507). Install the 4.5.2 runtime then upgrade to a current version of windows.

    You should first test if the app runs on 4.6.2 or 4.8. If it runs on 4.6.2 but not 4.8 you can start with a windows version 1507, 1511, 1607. As .net 4.* updates in place, it’s unlikely, that you have the app running on 4.5 unless the client machines have never been updated.

    Note: support for 4.5 and 4.5.1 ended back in 2016. Support for 4.5.2 ends next month. There will be no future security fixes after April 2022..

    Hi @RLWA32

    Thanks again. Apparently Microsoft will bundle/auto-install .NET 4.8 (together with .NET 3.5 as an option) once Windows 10 is installed. Is this the case also for the installation of Win 10 IoT?

    Secondly, is there any indication why the older .NET 3.5 is supported till 2029, whereas .NET 4.5.x is not?

    Kind regards

    Hello @Bruce (SqlWork.com)

    Thanks for the input which is helpful. Will installing Win 10 IoT also result in the automatic install of .NET 4.6+?

    Best regards
