[FIXED] How to prevent hide or override on a public property

Issue

I have an abstract base class that has a Property on it that I would like to prevent both hiding, aka new, and override on.

public abstract class DomainObject
{
    public bool IsDeleted { get; set; }
}

public class BankAccount : DomainObject
{
    public bool IsDeleted { get; set; }
}

The issue is: I need BankAccount to inherit from the base DomainObject class, so I can't mark it as sealed, but I want to prevent the situation, an override or new, of IsDeleted at compile time.

Solution

I've had this same need for the same reason that you mentioned in comments: preventing issues caused by generated code. My solution was to make this specific warning an error, which can be done by adding "0108" to the "Project Properties" => "Build" => "Treat warnings as errors" => "Specific warnings" list.

I'd be curious to know why this was considered to be only a warning and not an error in the first place. Surely, it is some "brittle base class" situation that I haven't considered...
