Question

我有服务。当我使用wcfTestClient测试时，该服务正常工作。当我从控制台应用程序客户端调用时，它会抛出以下错误：

无法找到引用合同的默认端点元素＆＃39; ICalculationService＆＃39;在ServiceModel客户端配置部分中。这可能是因为没有为您的应用程序找到配置文件，或者因为在客户端元素中找不到与此合同匹配的端点元素。

服务追踪：

描述：无法查找频道以接收传入消息。找不到端点或SOAP操作。源：System.ServiceModel.Activation.HostedHttpTransportManager / 28072850

可能出现的问题是什么？

参考：There was no channel that could accept the message with action

XSD文件：

可以在One WCF service – two clients; One client does not work

中找到所需的XSD

Answer 1

您的问题可能在您的客户端配置中。

<endpoint address="http://localhost:2724/CalculationService.svc/CalculationService"

您是否已将本地IIS配置为在端口 2724 ？

上托管服务

首先仔细检查一下。

编辑：如果您正在使用Visual Studio进行测试，请see this article获取有关配置特定端口号的建议。

Answer 2

让我承认这是我身边的错误。我将客户端配置保存在output.config文件中（由WCSF Blue工具生成）。当我将它复制到app.config时它运行正常。

服务可以从wcfTestClient运行，但在Console Application中失败
