如果我使用此代码：
//in this timeout code necessary?
ServiceClient.Timeout = 10;
ServiceClient.GetRestaurantsByNameAsync (MenuFinderApp.RestaurantSearchName);
ServiceClient.GetRestaurantsByNameCompleted += delegate(object sender, GetRestaurantsByNameCompletedEventArgs args) {
//code to show records
};
我返回了几条记录。如果我等待大约5-10分钟并再次执行代码，我会收到超时错误。为什么会发生这种情况，如何保持连接打开？我必须指定60分钟的超时时间吗？这是我的WCF服务的Web.config：
