Openmod Entity Framework could Could not set up parent class

[Yannnyan]

I was following up on the guide here https://openmod.github.io/openmod-docs/devdoc/concepts/databases.html, i've tried
deploying the plugin and loading the plugin, yet i've gotten a runtime exception that 'Could not resolve the signature of a virtual method assembly '. Can someone help?

Not sure but I think it's because you setup to use Microsoft.EntityFrameworkCore.Tools with a diff version than om.
Also is there anything else on logs?

I've tried resetting the server, reloaded the plugin with the right version Microsoft.EntityFrameworkCore.Tool for and got this msg
Could not load signature of Microsoft.EntityFrameworkCore.Infrastructure.RelationalOptionsExtension:ApplyServices due to: Could not load file or assembly 'Microsoft.Extensions.DependencyInjection.Abstractions, Version=3.1.19.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies.

What about
om remove Microsoft.EntityFrameworkCore.Tool
om install Microsoft.EntityFrameworkCore.Tool@3.1.19

[Yannnyan]

It seems to be fixed after some time that I havent touched it, I've commented out this line
<PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="3.1.32">
Thanks for helping!
