Thanks for tackling the line normalizations, I can imagine how annoying this must 🙈
there still appear to be 2 failures related to that:

I think I need to scrap this and start over. I believe the problem is with the O# implementation of ILegacyGlobalOptionsWorkspaceService that I added to Roslyn. I let it take all defaults because I didn't expect a lot of things to still be using the Legacy options, however, I see where it could be inheriting Environment.NewLine as its NewLine character instead of taking the appropriate formatting option.
