Just to let you all know:
We are using beta versions instead of latest stable builds. When branching off to a new version build of our app, I updated our ThinkGeo references/dependencies. After the updates, whenever I tried to show a polygon on our map, the app would crash. I checked the ThinkGeo version differences, and rolled them back one by one until everything worked as expected. I ended up rolling back 3 dependencies, in this order:
MapSuiteDesktopForWinforms-BareBone from beta 48 to 47
MapSuiteDesktopForWinforms-Standard from beta 48 to 47
ThinkGeo.MapSuite from beta 66 to 65
After rolling back ThinkGeo.MapSuite, the app ran as expected. We are running fine now.
Here is the exception info we encountered. Hope it helps:
