Look in the .config file - it's currently configured there.

There is an XML section called 'bindings" and inside there your bindings and options are set. Here's an example:

<system.serviceModel>
      <bindings>
        <basicHttpBinding>
          <binding name="BasicHttpBinding" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="2147483600" maxBufferPoolSize="2147483600" maxReceivedMessageSize="2147483600" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
            <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/>
            <security mode="Transport">
              <transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
              <message clientCredentialType="UserName" algorithmSuite="Default"/>
            </security>
          </binding>
        </basicHttpBinding>
