Our project was running on Unity 2019.4.37f1. I'm trying to use an external DLL(.Net Standart 2.0) which has a reference to EntityFramework Core(3.1.25 version) with Unity and I get the following error in Unity Hub(I have tested it in a visual studio project and it works fine):
Assembly 'Assets/dllName.dll' will not be loaded due to errors: Unable to resolve reference 'Microsoft.EntityFrameworkCore'.
Is the assembly missing or incompatible with the current platform? Reference validation can be disabled in the Plugin Inspector.
When I tried to remove EF Core reference from DLL and use it in Unity it works properly.
Note: You can reproduce the problem in any Unity project.
I have been searching about this but had no luck finding the right solution. Any help is appreciated greatly.
