title: Web.config is not transformed when debugging code
body: <p>I have a main <code>Web.config</code> file, and under that there is a <code>Web.Test.config</code>, <code>Web.Development.Config</code> etc.</p>
  
  <p>When I preview the transformation via SlowCheetah on the Test config, it appears to transform the values correctly.</p>
  
  <p>When I switch my build environment from Development to Testing and try to debug the application, the application runs under whatever values are in the main <code>Web.config</code> file (i.e. it is not transforming anything). </p>
  
  <p>How do I make the build environment pick the correct config when debugging rather than just always using the base <code>Web.config</code> file? Is this possible?</p>
