The Create Map Tile Package tool sees the map in the project and gives a drop down but Manage Tile Cache does not and I can find nothing it likes.

Nope, the Problem still persists.
Version: 1.4.1 -> GDB Mosaic Dataset, Raster Layers or Map Documents(MXD) are 4 choose.
There is still no way to generate a TileCache out of ArcGis Pro !
I tried to load an MXD File(10.3), this forced the Error 999999 😕
You're right, I wasn't looking at that tool. The create map tile package tool works fine, however.
Problem is back in 2.0. The Manage Tile cache tool still requires a .mxd. When I make a mxd in ArcMap and try to use it i get a weird 9999 error.

When can we use these tools in Pro?
