title: FxCop indirect reference to System.Core version 2.0.5.0
body: <p>I've got a project that uses Autofac, and the WebAPI integration</p>
  
  <p>We run FxCop over our solution, and on opening autofac, I get the following:</p>
  
  <blockquote>
    <p>The following indirectly-referenced assembly could not be found. This
    assembly is not required for analysis, however, without it, analysis
    results could be incomplete. This assemble was referenced by
    Autofac.dll</p>
    
    <p><strong>System.Core, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes</strong></p>
  </blockquote>
  
  <p>This causes the following error on our CI server:</p>
  
  <blockquote>
    <p>FxCop return code (516): PROJECT_LOAD_ERROR ASSEMBLY_REFERENCES_ERROR</p>
  </blockquote>
  
  <p>Is there a way to tell FxCop to ignore this?</p>
