Basically, im trying to convert a VehicleDTO, which has some properties, to my Vehicle model, which has a lot of more properties, so when i map it, the unmapped properties are null, and when its time to update it, that causes a couple of errors, like some values that cant be null, or just updates the object but clears the previous values and set them to null.

I’m running a net8.0 aspnet server using entity framework. One table in my database is for “Users”, but it contains 2 different types via a discriminator “Buyer” and “Seller”. In the code, Buyer and Seller are both subclasses of User
