Hi,

Same error, using Devart.Data.Oracle.EFCore 9.6.646. This is critical for us so would be great if a devart-offical could say something about it.

Great news,
I have the same problem. Do you have an estimated date for uploading the package to nuget?
Thanks!

Still waiting for a public release of this. Currently, I have the packages you linked to added to our internal NuGet repository.

Also waiting for a public release. In the meantime, I can confirm that the prerelease version of 9.6.659 indeed works as expected.
