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 CU,

    From a long-term perspective, why do you want the system to accommodate your application? Isn't it the application that accommodates the system? The version of .NET will only get higher and higher. You should handle it from the term of application.
    See: How to: https://learn.microsoft.com/en-us/dotnet/framework/migration-guide/

    Best regards,
    Seeya

    Hi Seeya

    The constraint is that one is dealing with legacy applications and updating the .NET framework will result in breaking changes, which is too costly hence a .NET framework update is not an option.

    Do Microsoft have an archive location for the security updates (for Windows 10 and .NET 4.5.x)?

    Kind regards
    CU

    You can find information about security and quality roll-up updates for the.net framework as well as security-only updates in the .net blog. For example net-framework-february-2022-security-and-quality-rollup

    Hello @RLWA32

    Thanks but I already know that before contacting Microsoft. Yes, there are .NET 4.5.x updates but they only apply to Windows 7, Windows 8 etc but not Windows 10.

    The following is a summary of the security updates that exist:

    OS | .NET | Update Exists ?
    Win 7 | 4.5.x | Yes
    Win 8 | 4.5.x | Yes
    Win 10 | 4.5.x | No

    Win 10 | 3.5 | Yes

    From the above, even .NET 3.5 has Win 10 updates but .NET 4.5.x has none (possibly because .NET 3.5 is supported till 2029). What we are after are .NET 4.5. security updates for Win 10.

    Regards
    CU
