The best way to refresh entities in your context is to dispose your context and create a new one.

If you really need to refresh some entity and you are using Code First approach with DbContext class, you can use

    public static void ReloadEntity<TEntity>(
        this DbContext context, 
        TEntity entity)
        where TEntity : class
    {
        context.Entry(entity).Reload();
    }

To reload collection navigation properties, you can use

    public static void ReloadNavigationProperty<TEntity, TElement>(
        this DbContext context, 
        TEntity entity, 
        Expression<Func<TEntity, ICollection<TElement>>> navigationProperty)
        where TEntity : class
        where TElement : class
    {
        context.Entry(entity).Collection<TElement>(navigationProperty).Query();
    }
