  <p>I have tried the following:</p>
  
  <ol>
  <li>Clean the solution and rebuild</li>
  <li>Remove the reference for the Business connector and then rebuild</li>
  <li>Added the reference for the Business connector for all the projects in my solution</li>
  <li>Changed the Build property Platform Target to x86 for all the projects</li>
  <li>Cleaned the Temp folder for the project</li>
  </ol>
  
  <p>Nothing seems to solve the problem.</p>
