[MonoTouch] Binding to 3rd party frameworks

[Andrew Young]

 Ok. So I've figured out that in order to bind to a 3rd party framework you need to add these extra args. 

-F{path to frameworks} -framework {framework name}

But now that the app can compile and deploy to the phone, it is crashing after I click a button which in turn performs an async web call using RestSharp saying:

"Job appears to have crashed: Segmentation fault: 11"

RestSharp seems like a pretty unrelated place in the code to crash in and the project doesn't crash when I remove all traces of the 3rd party framework. Crash reports seen in Xcode shows a different Exception Type varies each time I run it making debugging difficult.

EXC_BAD_ACCESS (SIGSEGV) KERN_PROTECTION_FAILURE  at 0x2fd00fe0
EXC_CRASH (SIGBUS) 0x00000000, 0x00000000
EXC_BAD_ACCESS (SIGSEGV) KERN_INVALID_ADDRESS at 0x00000000

Am I missing any extra args here?

After creating the bindings and adding it to my  MonoTouch proj, I get a "Undefined symbols for architecture i386" from mtouch. It is trying to reference a header that belongs to the 3rd party framework.
