Hi Kory Kramer,
I use the in_memory workspace in ArcMap all the time and was pleased to see that ArcPro now has the memory workspace. I was trying to use the CON tool with the memory workspace today but it kept throwing an error. I then searched the help and discovered this page where it clearly states that "Raster support in the memory workspace will be added in a future release of ArcGIS Pro".
Simple question do you have any idea when this will happen?
It would be extremely useful to all of us that create temporary datasets or are testing some logic without clogging up geodatabases/folders.
