comment Why ArcMap.Application.Document is null on run?
Did you try casting the hook passed to the constructor as an IApplication member variable and calling that instead?

comment GIS software recommendation
Are you wanting to do custom indoor routing? If so, you may want to refine your question. I think that will certainly narrow the field of potential candidates.

comment Unable to create object class extension COM component?
Of course the best thing to do would be to find the dll and register it in the "GeoObject Class Extensions" category using categories.exe.

comment Unable to create object class extension COM component?
Programmatically this can be done via IFeatureWorkspaceSchemaEdit.AlterClassExtensionCLSID. Not sure of a way to do it through the UI. If it's a personal mdb, you might try looking for a row in the ObjectClasses table for your featureclass, and clear out the EXTCLSID value for that row. Back up your mdb first.

Do you know if these featureclasses relied on custom class extensions?

comment Count overlapping polygons in single shape file with R
Here's a rather old VBA solution that leverages map topologies. It could be updated to C#, and maybe python, but not certain. forums.esri.com/Thread.asp?c=93&f=982&t=84656#249735

comment How to Predict demand on a bus route, considering variaton in kms and price?
I think this topic (referred to as "Elasticity of Demand") is relevant. Transit agencies have been accused of raising the price of bus transit (used by captive riders) to offset cost of funding rail transit (used by choice riders).

comment How can I delete relationship classes?
See my update. Sometimes deleting an element can confuse the implementation of the enumerator.
