Question

我有一个使用Windows服务的wcf服务应用程序。另外，我有一个连接到wcf服务的wpf应用程序。我一直无法打开wpf程序。这是我尝试通过在调试模式下按F5从Visual Studio打开wpf应用程序时得到的错误：

mscorlib.dll but was not handled in user code

Additional information: Could not connect to net.tcp://localhost:8732/Design_Time_Addresses/NextGenService/SimSession/. The connection attempt lasted for a time span of 00:00:02.2590000. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8732.

我在所选功能的wcf激活节点下都有Http和非http激活选项。所有与net.tcp有关的3项服务都在运行：Net Pipe Listener Adapter，Net.Tcp Listener Adapter，Net.Tcp Port Sharing Service。

我尝试了互联网上的所有建议，但没有一个对我有用。我还能做些什么来解决这个问题吗？谢谢。

我也面临同样的问题。

请检查您的Windows服务OnStart方法以获取以下行。

serviceHost = new ServiceHost(typeof(**WCFService**));

确保此WCFService实际上是您的WCF服务合同类而不是Windows服务类。互联网上有帖子为Windows服务而不是WCFService创建了这个ServiceHost，这是不正确的。
