✅ EFCore fetching all data in nearly all tables after a single insert

class MyDbObject
{
  public int Id {get;}
 //...
}

[StronglyTypedId]
readonly partial struct ObjectId
{
  // This and a lot of plumbing and parsong code is source generated, like a EFCore Value converter and so on.
  public int Value {get;}
} 

[StronglyTypedId]
readonly partial struct ObjectId
{
  public static implicit operator ObjectId(MyDbObject obj) => obj.Id;
} 

_dbContext.Add(myObjectInstance);
await _dbContext.SaveChangesAsync();
