[MonoDevelop] "File->New->Solution" code invocation??

[Vasili I. Galchin]

Hello,

    Where in "core" source code is the function that gets invoked when
I select "File->New->Solution" from the MonoDevelop IDE? I want to be
more self-sufficient in order to read code, i.e. follow bread crumbs.
;^)

Thanks,

Vasili
