comment Why do ArcMap.exe processes stay open after I close ArcMap?
Also, sometimes when the act of being just visible may not necessarily be enough to cause the circular reference - it may require some event to happen for that condition to manifest itself. For example, the command can be visible and everything is fine and dandy waiting for the "StartEditing" event to happen. Once that triggers, it decides to start grabbing references to other things - and there it sets up its other references which do cause the circular condition. This was a classic problem with VB extensions and even more with .NET commands because of the non-deterministic garbage collection

comment How to bypass 10 character limit of field name in ShapeFiles?
hahaha nice one @whuber :) I would argue that as consultants, it is our job to find sustainable solutions for our customers and avoid despair.com/consulting.html as much as possible. Sure you can actually build a field mapper that works as a library which is consumed by an ArcObjects Feature Class Extension (and thus honored by ArcMap/ArcCatalog) or ArcGIS Editor Extension. You could then patch every single other piece of software that is involved in your workflow to use your field mapper (QGIS/GDAL/Mapserver/whatever). Doable,expensive,and still requires a custom field mapper :(

I updated my answer above to explain why work-arounds are a bad idea when your customer just wants shapefiles.

comment Working with temporary files in ArcObjects using Geodatabases?
If memory serves me right, the InMemoryWorkspace will switch internally to a ScratchWorkspace once it hits a threshold of certain amount of features and then rearrange its internal references to make it transparent. So you are then really interacting with a ScratchWorkspace, you just do not know it. I don't remember if I added code for that or not, but I think I did... or maybe it was the ArcGIS Server folks when they were implementing disconnected editing, but I think that is how it works.

No no, there are so many cities that it seems to be a straight continuos line, but it is not :)
