Unless I am missing something it doesn't appear that I can edit a WFS-T service in ArcGIS Desktop even with the Data Interoperability Extension. When is this functionality going to be implemented in ArcGIS, or are there other 3rd party plugins available to do this?
Seems odd that you can create WFS-T services in ArcGIS Server, but you have no way of editing them without using an open source product like QGIS, etc.
