I chose to expose cli.h, since it's very simple :). My code generator is now debugged enough to generate all the things required for the ManagedAsterisk and ast_mono runtime to compile and allow access to a specific .h. Even the simple cli.h, which is only 92 lines long, requires about 500 lines of output (C and C#) to be fully wiredup (of course, this counts spacing and open/close braces).  

Anyways, a bit of tweaking the generated code (and applying the fixes to the generator), it now compiles just fine without any warnings or errors. Yey.
