title: In visual studio 2013 ctrl/f7 doesn't work
body: <p>I'm using Visual Studio Express 2013. I noticed sometimes <kbd>ctrl</kbd>/<kbd>F7</kbd> does not compile the file. It doesn't give any errors and doesn't list the file. Here is a sample:</p>
  
  <pre><code>1&gt;------ Build started: Project: DSM Driver, Configuration: Debug Win32 ------
  ========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
  </code></pre>
  
  <p>I added a line with <code>...</code> which would create an error (C code). So I know it is not trying to compile. If I use <kbd>F7</kbd> it does compile and does spot the intentional error line.</p>
  
  <p>A file in another project from the same solution does compile when I use <kbd>ctrl</kbd>/<kbd>F7</kbd>.</p>
  
  <p>So, I ran <code>Build-&gt;Clean</code> Solution but that did not help.</p>
  
  <p>It is not a matter the file being already up to date because <kbd>ctrl</kbd>/<kbd>F7</kbd> will always compile even if the file has not changed.</p>
  
  <p>Does anyone have any ideas?</p>
