Issue running code coverage with dotCover in release mode

Question

Has anyone successfully run coverage reporting using dotCover (and ideally TeamCity) while targeting release mode in the application? Here's the error message I received (this configuration works in debug mode):

Generate dotCover report (6s)

We would like to produce one set of compiled artifacts to pass through the delivery pipeline (including deployment). We didn't run into this problem with NCover - it was able to produce coverage on our release build.

Note: .pdb files are being generated in release mode

According to the logs, snapshot was taken normally and coverage statistics must be presented. Looks like source code build and coverage analysis are in different build configurations. You can either put build and coverage analysis in a single configuration or configure source code mapping by TC-parameter

dotNetCoverage.dotCover.source.mapping (format: path1 => path2)

Current checkout dir can be specified as % teamcity.build.checkoutDir%
