DbSet does not contain a definition for AddorUpdate

Question

Hi Everyone,

 

Do we have any alternate method for AddorUpdate in EF Core .

public virtual void AddOrUpdate(T entity)
{ #region Argument Validation if (entity == null)
{ throw new ArgumentNullException("entity");
}
#endregion
DbSet.AddOrUpdate(e => e.Id, entity);
SaveChanges();
}

I am getting an error at "DbSet does not contain a definition for AddorUpdate", Method can anyone help on this.
