Problem:
When using the CallUnManagedDll Sample which can be found on the supportline website an COBOLRuntimeException Error appeared. 174 file not in directory.
Resolution:
As described in the readme in the demo itself (and also in the source code *text* part) you need to add the cobcdll.dll and the cobcalldll.dll in the references. Also the kernel32.dll in windows/System32 needs to be added.
