Problem: Programmatically deleting a geometric network, then deleting Dataset in Treeview, will cause ArcCatalog to fatal

Description

Cause

This is a known issue.

Solution or Workaround

There are two workarounds for this problem:

  • Do not delete the feature dataset following this operation. Close and re-start ArcCatalog to delete the dataset.
