asp.net - WCF Service Error : Exception Details: System.Net.WebException: The remote server returned an error: (400) Bad Request

Question

I created a web service to upload files over http but on my first try, it is failing.

My web service is running on my local computer's IIS 7, under ASP.NET 4 Integrated App Pool. Here this is my web service's web.config;

<?xml version="1.0"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>

  <system.serviceModel>

    <behaviors>

      <serviceBehaviors>

        <behavior>
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>

        <behavior name="TransferServiceBehavior">
          <dataContractSerializer maxItemsInObjectGraph="2147483647" />
          <serviceThrottling maxConcurrentCalls="500"
                             maxConcurrentSessions="500" maxConcurrentInstances="500" />  
        </behavior>

      </serviceBehaviors>

    </behaviors>

    <bindings>
      <basicHttpBinding>

          </security>
        </binding>
      </basicHttpBinding>
    </bindings>

    <services>

      <service behaviorConfiguration="TransferServiceBehavior" name="TransferService">

        </endpoint>
      </service>

    </services>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" />

  </system.serviceModel>

 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

  <system.web>
    <!--<httpRuntime maxRequestLength="2097151" />-->

                 useFullyQualifiedRedirectUrl="true" executionTimeout="14400"   />

This is the web.config file of the client;

              </binding>
            </basicHttpBinding>

        <client>

                name="BasicHttpBinding_ITransferService" />
        </client>

    </system.serviceModel>
</configuration>

Here is the error I receive;

The remote server returned an error: (400) Bad Request.

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.225

The file that I am trying to upload is 217 KB so I am guessing the file size is not the problem here.

What do you think causing the error?
