Ошибка при развертывании службы WCF в приложении WPF
Я работаю над приложением WCF, запускаю простой сервис HelloWorld. Я разработал простое приложение WPF для размещения служб, т.е. запуска и остановки службы
Когда я пытаюсь протестировать этот сервис с URL " http://localhost:8087/MyServices/HelloWorldService" на WCFTestClient, я получаю следующую ошибку
Error: Cannot obtain Metadata from http://localhost:8087/MyServices/HelloWorldService If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address. For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange Error URI: http://localhost:8087/CreditUnionServices/HelloWorldService Metadata contains a reference that cannot be resolved: 'http://localhost:8087/CreditUnionServices/HelloWorldService'. <?xml version="1.0" encoding="utf-16"?><Fault xmlns="http://www.w3.org/2003/05/soap-envelope"><Code><Value>Sender</Value><Subcode><Value xmlns:a="http://schemas.xmlsoap.org/ws/2005/02/sc">a:BadContextToken</Value></Subcode></Code><Reason><Text xml:lang="en-GB">The message could not be processed.

The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding.</Text></Reason></Fault>HTTP GET Error URI: http://localhost:8087/CreditUnionServices/HelloWorldService There was an error downloading 'http://localhost:8087/CreditUnionServices/HelloWorldService'.

C# класс, чтобы открыть и закрыть сервис
public class ServicesHostManager
{
ServiceHost _helloWorldServicesHost = new ServiceHost(typeof(HelloWorldManager));
public void ProcessHelloWorldService(string _process)
{
if(!string.IsNullOrEmpty(_process))
{
try
{
if (_process.Equals("open_service"))
{
_helloWorldServicesHost.Open();
}
else if (_process.Equals("close_service"))
{
_helloWorldServicesHost.Close();
}
}
catch (Exception e)
{
System.Windows.MessageBox.Show(e.ToString());
}
}

У меня есть код обновления и сейчас он работает,
<system.serviceModel>
<services>
<service name="App.Services.Managers.HelloWorldManager" behaviorConfiguration="DefaultServiceBehavior">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8087/MyService"/>
</baseAddresses>
</host>
<endpoint address="HelloWorldService" binding="wsHttpBinding" contract="App.Services.Contracts.IHelloWorldService"></endpoint>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="DefaultServiceBehavior">
<serviceMetadata httpGetEnabled="True" httpsGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="False" />
</behavior>
</serviceBehaviors>
</behaviors>
Предыдущий комментатор был на правильном пути, вам нужно объявить конечную точку mex. mex - это то, что обеспечивает метаданные.
Попробуйте следующий конфиг:
<system.serviceModel>
<services>
<service name="App.Services.Managers.HelloWorldManager" behaviorConfiguration="SimpleWcfServiceBehavior">
<endpoint address="HelloWorldService"
binding="wsHttpBinding"
contract="App.Services.Contracts.IHelloWorldService">
</endpoint>
<endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" contract="IMetadataExchange"></endpoint>
<host>
<baseAddresses>
<add baseAddress="http://localhost:8087/MyService"/>
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="SimpleWcfServiceBehavior">
<!-- To avoid disclosing metadata information, set the values below to false before deployment -->
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
