  • 1.  IBM.EntityFrameworkCore .NET 8

    Posted Fri April 05, 2024 10:43 AM

    We are using the following packages, and ran into this error. The application that encountered this error is a .NET worker service running on a Windows Server 2019. It is running as a Windows service.

    Is this a known issue? Or is there a way to configure the connection to get around this error?

    Packages used:

    •  <PackageReference Include="IBM.EntityFrameworkCore" Version="8.0.0.100" />
    •  <PackageReference Include="Net.IBM.Data.Db2" Version="8.0.0.100">

    Hi Matthew,

    Would you try with latest package that is IBM.EntityFrameworkCore version 8.0.0.200 ?

    Hi Archana,

    Yes, we will give that a try. 

    Was this a known issue that was fixed in the latest version, or were there any known issues with the 8.0.0.100 version? I see that it was removed from nuget.org.
