c# - 为什么在 "Windows Class Library"项目中创建时未发现 wcf 服务？

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。现在我想将该服务添加到同一解决方案中的 Console 项目中。我单击“添加服务引用 -> 发现”，它找到了该服务。

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对我的 的引用>Console 项目，因此点击 Discover 不会返回任何内容。为什么？

创建Wcf Service Library 项目或Windows Class Library 项目和在Wcf Service Library 中创建时有什么区别？

已编辑

仅当服务位于 Wcf 服务库 中时，Discover 才有效。但是一旦我转移到其他项目(Console、Class Library)，Discover 就再也找不到它了。为什么？

经过一番检查后我得出结论，只有创建了WCF 服务库，您才可以使用Add Service Reference->Discover 按钮创建客户端，而无需显式运行主机，并且它会找到服务。

如果您创建的类库项目将包含您的服务文件，那么如果服务未托管(是未运行)。你应该运行主机，只有在它把服务地址放在地址栏并按Go

之后
