I am trying to create a point file in Arcgis runtime 100.x. It seems to go well enough, except I can't see how to create an index for it. If I try to start with a blank shape file that already has and index, then it throws a bunch of nonsense errors about features having been deleted in the file. I also tried using some of the other DLLs that are out there for creating shape files but they all seem to be missing the indexing.
I am creating a point file with over 300K points in it, then using spatial queries to get information from it. Without the index it is painful.
Any thoughts on how I can do this in runtime with shape files or any other data format that runtime supports.
