对使用服务的非库应用程序进行单元测试可能会导致此问题。

The information that others have entered addresses the root cause of this. If you are trying to write automated test cases and the unit you are testing will actually invoke the service interface, you need to add the service reference to the test project. This is a flavor of the application using library type of error. I did not immediately realize this though because my code that consumes the interface is not in a library. However, when the test actually runs it will be running from the test assembly, not the assembly under test.

向单元测试项目添加服务引用解决了我的问题。

嗨，我也遇到过同样的问题，但是最好的解决方案是让. net来配置你的客户端配置。当我使用http:/namespace/service.svc?查询字符串添加服务引用时，我发现了这一点。wsdl=wsdl0，它不会在客户端创建配置端点。但是当我删除wsdl-wsdl0并且只使用url http:/namespace/service时。Svc，它在客户端配置文件中创建端点配置。简而言之，去掉“?WSDL=WSDL0”。

There seem to be several ways to create/fix this issue. For me, the CRM product I am using was written in native code and is able to call my .NET dll, but I run into the configuration information needing to be at/above the main application. For me, the CRM application isn't .NET, so I ended up having to put it in my machine.config file (not where I want it). In addition, since my company uses Websense I had a hard time even adding the Service Reference due to a 407 Proxy Authentication Required issue, that to required a modification to the machine.cong.

代理解决方案:

为了让WCF服务引用工作，我必须从我的DLL的app.config复制信息到主应用程序配置(但对我来说是machine.config)。我还必须将端点信息复制到同一个文件中。一旦我这么做了，它就开始为我工作了。

向单元测试项目添加服务引用解决了我的问题。

我曾经遇到过这个问题。这是因为我还在开发使用WCF服务的接口。我配置测试应用程序和继续开发。然后在开发中，我改变了一些服务的名称空间。所以我再次检查了“系统”。serviceModel ->客户端->端点->合同”。配置匹配WCF类。那么问题就解决了。

在测试了几个选项之后，我最终通过使用

contract=“IMySOAPWebService”

例如，在配置中没有完整的命名空间。由于某种原因，全名没有正确解析
