Question

I have written my service in framework 4.0 using C#. It’s an simple method which returns a value

The Web.config is like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.web>
    <machineKey validationKey="0E1F430D6FFFA91FBEDAEC1D2DDAAC2127EB055DBAFB78328C5BDE83249A94EA66400453B" decryptionKey="A13EACEAAABBECF2D06619924A8" validation="SHA1" decryption="AES" />
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <services>
      <service name="DecryptCookie.Service1">
        <host>
          <baseAddresses>
            <add baseAddress = "http://localhost:8732/Design_Time_Addresses/WCFandEFService/ProductService/" />
          </baseAddresses>
        </host>
        <endpoint address=""  binding="wsHttpBinding"    contract="DecryptCookie.IService1">
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract = "IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>  
</configuration>

When I try to consume the service, I am getting an error like this:

Error: The server was unable to process the request due to an internal error. 
For more information about the error, either turn on
IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from
the configuration behavior) on the server in   order to send the exception
information back to the client, or turn on tracing as per the Microsoft .NET
Framework 3.0 SDK documentation and inspect the server trace
logs.System.Exception {System.ServiceModel.FaultException}

I am not sure what the problem is.

When I get these cryptic errors, I turn on tracing and create a service log (.svcLog). You can then load/read this file using the Service Trace Viewer tool. This will give you detailed data regarding the error(s). Follow the instructions on this link – http://msdn.microsoft.com/en-us/library/ms732023.aspx
