I don't know if this is a regression or not, but I added a fix to specflow to include an additional #line pragma which enabled the starting markers to show up in the feature files when using scenario outlines:

I've noticed that this is no longer working with the latest version of ncrunch in VS2015. When I check with the same version of NCrunch in 2013 I get the markers by the examples allowing me to start the tests. When I check in VS2015 I don't see the markers. I checked with 2.20.04 in both after noticing when I had 2.23.03 installed for VS2015, in case it was an issue in a newer version.
I havn't checked in the lastest version with VS2013, but will try and do that today.
