我已經創建了WCF服務,並嘗試在Managed Windows Service中托管(接下去的文章 )。 該服務已啟動並正在服務中運行。
嘗試在客戶端應用程序中添加URL(net.tcp:// localhost:8000 / UserManagement)時,出現錯誤:
元數據包含無法解析的引用:“ net.tcp:// localhost:8000 / UserManagement”。 無法連接到net.tcp:// localhost:8000 / UserManagement。 連接嘗試持續時間為00:00:00.9531433。 TCP錯誤代碼10061:無法建立連接,因為目標計算機主動拒絕了127.0.0.1:8000。 無法建立連接,因為目標計算機主動拒絕它127.0.0.1:8000如果在當前解決方案中定義了服務,請嘗試構建解決方案並再次添加服務引用。

跟隨您提供的MSDN鏈接后,我也面臨同樣的問題。 該代碼有錯誤。
在您的OnStart方法中,
serviceHost = new ServiceHost(typeof(UserManagementService));
而不是為UserManagementService創建ServiceHost,請在此處使用實際的WCF服務類名稱。 這行代碼將創建Windows服務而不是WCF服務的實例。 我能夠使用它修復我的。
您需要使用地址
net.tcp://localhost:8000/UserManagement/mex
在配置服務參考時。
或者,您的元數據終結點應使用mexHttpBinding
並且應在服務行為httpGetEnabled
設置為true
<serviceMetadata httpGetEnabled="true"/>
