Question

我将 Wcf服务库项目添加到解决方案中，并创建了2个类（Service1，IService1）和配置文件。现在，我想在同一解决方案中将该服务添加到我的控制台项目中。我点击＆＃34;添加服务参考 - ＆gt;发现＆＃34;它找到了服务。

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，因此点击发现并不会返回任何内容。为什么呢？

创建 Wcf服务库项目或 Windows类库项目并在 Wcf服务库中创建相同内容时有何不同？

被修改

仅当服务位于 Wcf服务库时，Discover才有效。但是，一旦我转移到其他项目（控制台，类库），Discover就不再找到它了。为什么呢？

Answer 1

经过一些检查后，我得出的结论是，只有创建 WCF服务库，才能创建具有Add Service Reference->Discover按钮的客户端，而无需显式运行主机，它将找到该服务。

如果您创建了类库项目，那么将包含您的服务文件，因此如果未托管服务（未运行），则无法使用Add Service Reference->Discover创建客户端。您应该运行主机，并且只有在将服务地址放在地址栏中并按开始

之后

Answer 2

看起来只有在使用wcf项目模板创建项目时才显示WCF选项，如果您有一个现有项目（类库），您可以通过在第一个属性组中添加它来转换它更多讨论Here < / p>

在第一部分中，添加以下行： {3D9AD99F-2412-4246-B90B-4EAA41C64699}; {FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}

Answer 3

在项目属性Wcf options start host

中启用

Answer 4

我有同样的问题。转到“调试”->“开始而不调试”。这将启动主机和客户端应用程序。然后转到客户端并添加服务参考。换句话说，该服务必须正在运行

为什么在＆＃34; Windows类库＆＃34;中创建wcf服务时未发现它？项目？
