the code is not compiled with mcs or csc, it's compiled with the bf
compiler.

the only thing that is compiled with mcs or csc is the bf compiler, but that
has no effect on what the bf compiler outputs.

there's only one function ;-)

the compiled program contains only about 10 to 15 of the simplest opcodes. I
don't think the problem is in the lack of 'ahead-of-time' compilation as the
program is very small and it has passed all possible code-paths within a
second. The real problem becomes apparent a few seconds later when it
becomes increasingly difficult to find the next prime number.
