I've started using NCover to monitor the test coverage on a CruiseControl.net project. Disappointed with the included version of the ncover report I quickly through together a new version of the NCover.xsl to be used by CruiseControl.net. Simply download the file and copy it to: cruisecontrol.net/webdashboard/xsl/

It's based on the original ncover.xsl but inspired by the version from Yves Lorphelin's code coverage tool NCover
