So I already have  cs-parser.cs, the problem is that the unknown format file cs-parser.jay is used instead of cs-parser.cs,
I see this while I'm debugging the program. How to fix that?
My program is using NRefactory v5.2
Here is program uploaded:

Noticed under cs-parser.cs the presence of
#line 2940 "cs-parser.jay"

so I've replaced all strings "#line " with "//#line "  - just mark these wit comment
And I got it working.
