Hi, thanks for posting!

I have no personal experience with Swashbuckle, but my first guess would be to check that you have the pre/post build events enabled in NCrunch - http://www.ncrunch.net/documentation/reference_project-configuration_run-pre-or-post-build-events.

If this doesn't work, you may need to take a look at how Swashbuckle is tied into your build system. This means opening up your project file in a text editor and examining the XML to see how this tool is being referenced. It's possible they have code specifically designed to exclude tools like NCrunch (which you could theoretically work around).

Note that generating XML documentation on NCrunch builds will likely increase your build times significantly. It may be worth looking at ways to do this inside the test code itself so you don't add seconds to your cycle times for the majority of your tests that likely don't need it.
