Accessing the NXOpen.Features.FeatureCollection through NXOpen .NET binding in NX 2312.5001 throws a System.EntryPointNotFoundException:
"Unable to find an entry point named 'XJA_FeatureCollection_enumerate' in DLL 'libpartmodl'".
SolutionAs immediate workaround, the user can safely backup and overwrite the related library "NXBIN\managed\NXOpen.dll" in NX 2312.5001 with the version from an earlier NX 2312 release, for example from NX 2312.4001.
This issue will be fixed as soon as possible with an upcoming update.
