Answer 1

的OrganizationService到底WCF服務......和你有一個現場部署的好處的話，也許你」請重新發送一個太大的請求，或者CRM可能會在超時之前回復您的請求。

無論如何，您可能需要考慮增加綁定配置中的超時值。

Answer 2

您的問題很可能是由連接超時造成的。 對於異步操作，WCF不會在連接超時時拋出TimeoutException。相反，它會將CommunicationException與內部異常WebException與狀態WebExceptionStatus.RequestCanceled一起拋出。

響應超時爲同步和異步操作引發TimeoutException。
