Is there a way to notify teamcity when ever someone does a commit to a repository on visual svn? This is so every time someone commits to the repository a build in teamcity will trigger immediately without the developer having to wait for polling to kick in on its set time interval.
You could probably do something using Subversion hooks to achieve that, but is it really worthwhile? You could set your TeamCity server to poll every 10 seconds, which is nothing in terms of a performance hit to the SVN repository and probably nothing much in terms of the wait for developers. (I mean, how long does your build take?)
