为什么在"Windows类库"项目中创建wcf服务时未发现它？

Question

我将Wcf服务库项目添加到解决方案中,它创建了2个类(Service1,IService1)和配置文件.现在我想在同一个解决方案中将该服务添加到我的Console项目中.我单击"添加服务引用 - >发现",它会找到该服务.

当我创建Windows类库项目并在那里创建与刚刚创建的Wcf服务库项目相同的示例,然后尝试将其添加为我的控制台项目的引用,因此单击Discover不会返回任何内容.为什么？

当我创建Wcf服务库项目或Windows类库项目并在那里创建与Wcf服务库相同时,有什么区别？

编辑

在Discover只有当服务是作品WCF服务库.但是一旦我转移到其他项目(控制台,类库),Discover它就不会再找到它了.为什么？

经过一些检查后,我得出的结论是,只有创建WCF服务库,才能使用Add Service Reference->Discover按钮创建客户端而不显式运行主机,它将找到该服务.

如果您创建将具有服务文件的类库项目,那么Add Service Reference->Discover如果未托管服务(未运行),则无法创建客户端.您应该只在将服务地址放在地址栏中并按Go后运行主机
