Runtime exception : eKey not found on plugin

[Anonymous]

I'm writing a plug-in for ACAD 2012 that makes a data extraction and outputs it to a txt file. I am developing on VS2015; targeting the .Net 3.5 framework.

I have been debugging a script that uses the code for the data extraction class based on this post . however, when the command runs, I get an error at the line  setting.DrawingDataExtractor.DiscoverTypesAndProperties(dwgpath); which causes  Autocad to throw a runtime exception: eKeyNotFound.

I traced the stack calls and the error says it is in the  AcdbMgd.dll that the error is being thrown; Stack trace and command code  function included below. I Don't really know where to go from here. AutoCAD seems to recover on small dwgs after throwing the error, but on a more complex dwg, it just throws the exception repeatedly and stalls out.

Never mind, apparently the hang time was caused by the extra info in the Debug version of the dll. the Release configuration had no such issues when loaded in autocad (not debugging)

Hi friend, did you manage to find a solution? I'm experiencing a similar problem.
