WCF库项目中未在Windows窗体应用程序中生成操作合同。 [英] Operation Contracts not Generated in Windows Form Application from a WCF Library Project.
本文介绍了WCF库项目中未在Windows窗体应用程序中生成操作合同。的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
大家好。
我创建了一个WCF库项目。我已经在WCF测试客户端测试了它，一切都按预期工作。
当我将服务添加为Windows窗体客户端的服务参考时，对于某些未知的原因，我只能得到一份操作合同（在IExam.cs中定义，名为
bool AddExam（...）
这是我的合同：

And when I create the proxy to start calling the Operation Contracts, I can only get
the Operation Contract defined:
bool AddExam(...);
Why are others not available on the client side and what can I do to make them available? I am totally stuck here.请帮我。 I have looked through the internet for a solution for this but I just can’t find any.
解决方案 you are moving on the right path, you just need to care of the following steps :
1- Make all the methods ’public’ for example your method
private UserData GetUserData(string userName)
{
...
}
is a private method which means you wont be able to access from outside the class.
2- Make sure all operation contracts of your methods are implemented inside the interface class of the service not outside it.
make sure to browse the service file itself ’service.SVC’ and make sure that all your methods are there in the XML of it.
Hi all.
I created a WCF library project. I have tested it n the WCF Test Client and everything works just as expected.
When I add the service as a service reference for a Windows Form client, for some unknown reason, I can only get one Operation Contract (defined in IExam.cs called
bool AddExam(...) despite having others exposed from the service side!
