<p>What does this option do? It is accessible from the Build menu.</p>
| <p>It deletes all the compiled and temporary files associated with a solution. It ensures that the next build is a full one, rather than only changed files being recompiled.</p>
| <p>FYI, neither Clean nor Rebuild will delete non-build files, eg files copied during a pre-build command. I had been confused about that!</p>
