title: Configure WPF client to run 64bit
body: <p>We have some code that uses Entity Framework against a DB2 database. </p>
  
  <p>When we try to use transaction scope, we get a message "The Under lying provider failed on Open".</p>
  
  <ul>
  <li>We only get this error when to run from the WPF client. </li>
  <li>We do not get this error when we run from a unit test.</li>
  <li>The DB2 provider is 64bit</li>
  </ul>
  
  <p>The difference that we have been able to find is that the unit test is configured as Any CPU, but the WPF project is configured as x86.</p>
  
  <p>The problem is that the Visual Studion UI does not allow us to select anything other than x86 for the WPF project. </p>
  
  <p>Is this a limitation of WPF projects? If not how do we configure a WPF project as Any CPU?</p>
