WCF: ASP.NET Hosting - Endpoint not found

Question

I get "Endpoint not found" when attempting to access my service via the browser at

http://localhost:10093/Services/Service1.svc

I get "Error: Cannot obtain Metadata from http://localhost:10093/Services/Service1.svc" when attempting to access the same address from the wcftestclient.

If I place a breakpoint in the service implementation it is hit, so I assume the svc file is setup correctly:

<%@ ServiceHost Language="C#" Debug="true" 
Service="MyApp.Core.Service.Service.MyAppService,MyApp.Core.Service" 
Factory="CommonServiceFactory.WebServiceHostFactory,CommonServiceFactory" %>

Here is my config:

<system.serviceModel>
    <services>
      <service name="MyApp.Core.Service.Service.MyAppService,MyApp.Core.Service"
               behaviorConfiguration="MainServiceBehavior">
        <endpoint name="newEndpoing" 
             binding="basicHttpBinding" bindingConfiguration=""
             contract="MyApp.Core.Service.IMyAppService" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MainServiceBehavior">
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

Answer 1

So you have a *.svc file to host your service. Can you right-click in Visual Studio on that file and say "Show in Browser" ? Do you get anything there, or does it throw an error right away??

Next: your service endpoint has no address="" attribute, which I believe is mandatory - try adding that (even if you don't specify an address in it).

If you're hosting in IIS, your service address is defined by the virtual directory where your SVC file is present, and the SVC file itself - you might not be able to define a specific port or anything (IIS will handle that).

So try to connect to

http://localhost/Services/Service1.svc

Does that work by any chance??

Update: reading your post again more closely, you're specifying a special factory for the service - WebServiceHostFactory. Is this the default WebServiceHostFactory provided by .NET, or is that something you built yourself??

The point is: the .NET WebServiceHostFactory will use the webHttpBinding for RESTful WCF services - that won't work with an endpoint specifying basicHttpBinding, nor will the REST service have any metadata....

Update #2: try to use just the service's fully qualified class name, but without the assembly specification, in both your SVC file, and the config file.

So change this:

Service="MyApp.Core.Service.Service.MyAppService,MyApp.Core.Service" 

to this:

Service="MyApp.Core.Service.Service.MyAppService" 

SVC file:

<%@ ServiceHost Language="C#" Debug="true" 
Service="MyApp.Core.Service.Service.MyAppService" %>

Config file:

<services>
  <service name="MyApp.Core.Service.Service.MyAppService"
           behaviorConfiguration="MainServiceBehavior">
     <endpoint name="newEndpoing" 
          binding="basicHttpBinding" bindingConfiguration=""
          contract="MyApp.Core.Service.IMyAppService" />
  </service>
</services>

Your error message is "Cannot obtain Metadata" and you do not have a MetadataExchange endpoint defined. You do have httpGetEnabled="True", which is also required.

Try defining a MEX endpoint, for details how to see: http://bloggingabout.net/blogs/dennis/archive/2006/11/09/WCF-Part-4-3A00-Make-your-service-visible-through-metadata.aspx

Hello, my web.config for my WCF service is very similar to yours. You definitely have to add the MEX endpoint like Shiraz said. I've added a behavior configuration that lets any message size go through the WCF. Try to use these settings if it can help you (don't forget to change the contract settings):

<system.serviceModel>    
<diagnostics>
  <messageLogging logMalformedMessages="true" logMessagesAtTransportLevel="true" />
</diagnostics>
<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_IService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="524288000" maxBufferPoolSize="524288000" maxReceivedMessageSize="524288000" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
      <readerQuotas maxDepth="500000000" maxStringContentLength="500000000" maxArrayLength="500000000" maxBytesPerRead="500000000" maxNameTableCharCount="500000000" />
      <security mode="None">
        <transport clientCredentialType="None" proxyCredentialType="None" realm="">
          <extendedProtectionPolicy policyEnforcement="Never"/>
        </transport>
        <message clientCredentialType="UserName" algorithmSuite="Default"/>
      </security>
    </binding>
  </basicHttpBinding>
 </bindings>
<behaviors>
  <serviceBehaviors>
    <behavior name="serviceBehavior">
      <dataContractSerializer maxItemsInObjectGraph="6553600" />
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>

  <service behaviorConfiguration="serviceBehavior" name="RC.Svc.Web.TPF.Service">

       bindingConfiguration="BasicHttpBinding_IService"
       contract="RC.Svc.Web.TPF.IService" />
    <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
