title: SSRS error on preview : "The size necessary to buffer the XML content exceeded the buffer quota" hides original error
body: <p>I understand that there is definitely something wrong with my report (e.g. columns missmatcch) and I need to correct it but what I see is the WCF error message that hides actual problem and exactly this hiding irritates me much more than original problem: columns missmatch.</p>
  
  <p>I guess we need to adjust the WCF 'buffer size' and we will get original problem message. But where is the config file?
  Text search of "system.serviceModel" in the C:\Program Files (x86)\Microsoft Visual Studio 10.0  doesn't bring good idea... </p>
  
  <p>P.S. Since this is just preview of report I do not think that it is SSRS configuration problem. Problem localised somewhere in DevStudio process or int the DevStudio's internal web server process ...</p>
  
  <p>P.P.S Please help me too improve the question. I see that responders doesn't understand what kind of help I need.</p>
