❔ Ef Core Constructor problem
Hello its my first big project with ef. I have an class with 3 attributes and one constructor that is calling the base constructor. My Class inherit from another class.
The problem is that ef core need an parameter less constructor. I tried to add an private constructor but its not working.

Add a public parameterless constructor
Or better yet, just remove the constructors you have and use
required
properties insteadA

Remove ctor from that class as well
Or just add a public parameterless ctor, that should work as well

One thing that comes to mind, is creating your own class that mirrors what the class from the nuget contains, use that class with EF, and just map between them as needed
