WCF: The connection was closed unexpectedly

When SoapUI gives you a hard time and just closing connection, you should try this out.

Insert this config into your x.config file:

<system.diagnostics>
    <!-- This logging is great when WCF does not work. -->
    <sources>
      <source name="System.ServiceModel" switchValue="Information, ActivityTracing" propagateActivity="true">
        <listeners>
          <add name="traceListener" type="System.Diagnostics.XmlWriterTraceListener" initializeData= "c:\temp\trace.svclog" />
        </listeners>
      </source>
    </sources>
  </system.diagnostics>


And use svctraceviewer.exe to view the file.
