I forgot to mention the new targets in the previous posts. If you want to generate either the NCover or NDepend reports like the ones available from TeamCity use these targets.
If you run
nant coverage it will enable running
nunit-console under NCover to produce the coverage XML log files, and run a build.
The target will also generate the summary coverage report.
nant ndepend will run a build and generate the report from the artifacts.
