Can you post how your makefile looks like? You have probably some problem in linked libraries...

Hello Yogesh,

SImply I have exported dll using extern "C" in toolkit coding & directly loaded it into my C# Program instead of add reference method

I have moved to win32 dll application instead of makefile project.
