title: Assembly references missing errors while building solution on TFS 2013
body: <p>i have a solution which contains 3 projects (DAL,BLL and Utility) and one website.</p>
  
  <p>I tried to build solution locally but it was giving some missing references errors. i added missing dll's and build was success locally.</p>
  
  <p>i checked in whole solution to TFS 2013 server. and tried to build solution on tfs through build definition. Butbuild fails with many errors (missing assembly reference).</p>
  
  <p>in source control i cant see any bin file so that i can add dlls.</p>
  
  <p>What am i missing? how can i add referenced to a project on TFS?</p>
