Is it safe to implement GetHashCode by returning an unique ID from the object?

Question

Let's say I have a POCO that represents a database row. I have access to the ID of that row.

Is it safe to implement GetHashCode and Equals by leveraging that unique ID ?

public class Project
{
    public string ID { get; }
    public string Name { get; set; }
    public override bool Equals(object obj)
    {
        var pr = obj as Project;
        if (pr == null) return false;
        if (pr.ID == null) throw new InvalidOperationException("Attempt to .Equals an entity with null ID");
        return pr.ID == ID;
    }
        
    public override int GetHashCode()
    {
        if (ID == null) throw new InvalidOperationException("Attempt to .GetHashCode on an entity with null ID");
        return ID.GetHashCode();
    }
}

I believe this could work because

• ID is not mutable
• I handle the case where ID is null

Any thoughts on that ?
