<p>I currently use AnkhSVN to integrate subversion into Visual Studio. Is there any reason I should switch to VisualSVN?</p>
<p>AnkhSVN is free (in more than one sense of the word) while VisualSVN costs $50. So right there unless I'm missing some great feature of VisualSVN I don't see any reason to switch.</p>
| <p>I used VisualSVN until Ankh hit 2.0, and ever since, I've abandoned VisualSVN. Ankh has surpassed VisualSVN in functionality, in my mind, and all the 1.x perf and integration issues are gone.</p>
| <p>The main thing is that VisualSVN uses TortoiseSVN for nearly all of its UI. So you only really have to set up one client (preferred diff viewer, etc), and you can take advantage of things like the same "Previous messages" button on the Commit dialog, whether you're committing from Explorer or Visual Studio.</p>

<p>How do I uninstall a Windows Service when there is no executable for it left on the system? I can not run <code>installutil -u</code> since there is not executable left on the system. I can still see an entry for the service in the Services console. </p>
