Looks like there was a bug in the single-argument Parser() constructor,
so Parser(lang) always gets the wrong answer.  You should be able to use:
   Parser(lang, null, null)
in the released software to get the "ntriples" or any other parser.

I've commited a fix to SVN csharp file Parser.cs to make the single
argument form work in:
