WCF IIS server configuration

Question

I have Windows Server 2008 R2 with IIS7 on it. I deployed WCF service on it. When I specify WCF service address in browser (local or external machine) http://sbkisourcedev01/VCIndex/Calculator.svc?wsdl I am getting service description in browser. However when I am trying to add reference to the project to that service I am getting following error:

The document was understood, but it could not be processed.  

  - The WSDL document contains links that could not be resolved.
  - There was an error downloading 'http://sbkisourcedev01/VCIndex/Calculator.svc?xsd=xsd0'.
  - The underlying connection was closed: An unexpected error occurred on a receive.
  - Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
  - An existing connection was forcibly closed by the remote host

Metadata contains a reference that cannot be resolved: 'http://sbkisourcedev01/VCIndex/Calculator.svc?wsdl'.
Content Type application/soap+xml; charset=utf-8 was not supported by service http://sbkisourcedev01/VCIndex/Calculator.svc?wsdl.  The client and service bindings may be mismatched.
The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'..
If the service is defined in the current solution, try building the solution and adding the service reference again.

I have this service running on Windows 7 and it is okay. So I believe there is something with my W2K8 IIS configuration settings.

Here is my config file:

  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="basicHttpBindingConfig" />
      </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="serviceBehavior">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    <services>
      <service behaviorConfiguration="serviceBehavior"
               name="WCFVCIndex.Calculator">
        <endpoint address=""
                  binding="basicHttpBinding"
                  contract="WCFVCIndex.ICalculator"
                  bindingConfiguration="basicHttpBindingConfig" />
        <endpoint address="mex"
                  binding="mexHttpBinding"
                  contract="IMetadataExchange" />
      </service>
    </services>
  </system.serviceModel>

Thanks in advance.

The problem was with WCF identity permissions. The identity that is used for the application pool that hosts the WCF service must have full NTFS permissions on the %WINDIR%\temp folder. After changing that permission to my identity (LOCAL SERVICE) on C:\Windows\Temp I was able to add service reference to WCF service.
