WCF service is not getting called
- by Cheranga
I have a web solution and I have a WCF service project inside it. We need to support "cookieless". so in the web.config, it's set as
<sessionState
mode="SQLServer"
sqlConnectionString="Data Source=ds;Initial Catalog=db;User Id=uid;Password=pwd"
allowCustomSqlDatabase="true"
cookieless="true"
timeout="720"
regenerateExpiredSessionId="false"/>
The WCF service will be supporting sessions, so we have also set "aspNetCompatibilityEnabled" to true in web.config.
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"
multipleSiteBindingsEnabled="true"/>
The service and interfaces are as follows,
[ServiceContract(SessionMode=SessionMode.Allowed)]
public interface ICDOCService
{ }
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class CDOCService : ICDOCService
{ }
The problem we are facing is we cannot access the service from any client application. (web app, WCF test client)
The following error is showing, when we access it via WCF Test client,
Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.
The content type text/html; charset=UTF-8 of the response message does not match the content type of the binding (multipart/related; type="application/xop+xml"). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 1024 bytes of the response were:
