Question

使用我的WCF服务时遇到问题。我在控制台应用程序中使用了我的WCF服务，它可以正常工作直到100个请求（循环中）。但它在100次请求后停止工作。我已经用过了

<serviceThrottling
                    maxConcurrentCalls="500"
                    maxConcurrentInstances="500"
                    maxConcurrentSessions="500"/>

在我的配置中，但它对此问题没有影响。我在每次调用服务后都关闭了连接，但问题仍然存在。

非常感谢任何帮助。

下面是我的web.config：

显然，问题是Package Class中的GetDestinationHotelId方法中的打开数据库连接。由于异常并且在达到100个打开的连接 MAX CONNECTION POOL LIMIT 之后，DB连接未关闭。

我真的很傻： - （

100次通话后，WCF服务停止工作
