c# - Can private setters be used in an entity model?

I'm just starting out with Entity Framework and I'm concerned about the ease with which a primary key can be overridden. I know I can protect this model in my controller (I'm using WebAPI with ASP.NET MVC 5), but I am wondering if it is possible to prevent anyone setting the ID of my model from the model itself via annotations or something?

Basically can I do this:

public int ID { get; private set; }

or something similar, in an EF6 model?

If this is easily found through Google then I don't know the terms to search. I've not been able to find anything that really answers this.

Yes you can, and it should work just fine. Per this blog post by Julie Lerman (who's Microsoft's Entity Framework MVP, so I highly recommend that you read her blog on your journey through EF!):

Entity Framework requires a parameterless constructor in order to materialize objects returned from queries (or loading). I have made this concession in my class but notice that it is a private constructor. So I’m still protecting my class. Nobody can access it. But EF is still able to populate this class when I execute queries. And no, I’m not doing some magic to tell EF to use my public constructor. It really uses the private constructor.
