I am also having the same problem in my application, and I have not found a
workaround other than to write the code in C++, compile it in a shared
library, and import the functions into my Mono application. I am curious to
know if you or anyone else has found a solution to this problem, as the
shared library approach is undesirable for portability reasons.
