I have an InMemoryFeatureLayer with some 40k features in it and they all need to be deleted. The current method being used is to delete them individually, but it's taking a really long time to do. Is there anyway to just delete them all at once? It seems like it ought be a routine thing to do, but in all my searching I cant seem to find any way to do it.
The person who normally does the GIS development is out and I'm not very familiar with Map Suite so I apologize if this is an obvious question.
