title: Service Reference Update : generating redundant files
body: <p>When we <code>Add Service Reference</code>, Visual Studio creates xsd files as below:</p>
  
  <ol>
  <li>MyService1.xsd</li>
  <li>MyService2.xsd</li>
  <li>MyService3.xsd</li>
  </ol>
  
  <p>Along with wsdl and .svcmap files.</p>
  
  <p>On subsequent updates, using <code>Update Service Refernce</code>, <strong>rather than</strong> updating above files VS 2010 keep adding more &amp; more files appending their names..</p>
  
  <ol>
  <li>MyService31.xsd</li>
  <li>MyService32.xsd</li>
  <li>MyService33.xsd
  <strong>....</strong></li>
  </ol>
  
  <p>This creates trouble while checking-in files &amp; scheduled builds in continuous integration environment fails. :-( without any mistake on coding side.</p>
  
  <p>How do you handle this scenario ? Can we force <code>Visual Studio</code> to force update existing files ?</p>
