Declaration

LazyAsync<DbData> lazyData = LazyAsync.Create(GetDbData);

private async Task<(DbData, DateTime renewAt, DateTime expiresAt)> GetDbData()
{
    DbData data;
    using (var ctx = dbFactory()) 
    {
        // getting data from db
    }
    return (data, DateTime.UtcNow.AddHours(1), DateTime.UtcNow.AddHours(12));
}

Implementaion 2

private async Task<(DbData, DateTime renewAt, DateTime expiresAt)> GetDbData()
    => (await _someService.GetDbData(id), DateTime.UtcNow.AddSeconds(Ttl >> 1), DateTime.UtcNow.AddSeconds(Ttl))
