Great Info: Here's my work flow.
1. Add Aerial or Feature Class
2. Set Data Frame Properties
a. Custom Extent - Current View
b. Define Projection to Data Frame to (Mash w/ BING) - WGS 1984 Web Mercator (Auxiliary Sphere).
3. Save MXD
4. Publish MXD or MSD to AGS
5. Cache Service
a. Have tried many formats
b. Aerial preferred JPEG or PNG32
c. 72,222 down to 1000 scales
6. Anti - Aliasing
a. Force and Best
7. Add Service as Base Map in MPC
8. Save AS Mobile Project directly to AGS
9. Open in ArcGIS Mobile
If I Add a Published Dynamic Operational Layer on top of Cached Aerial the Dynamic Service only appears.
I've tested this with just the cached Aerial as well, it does not show.
Please help and thank you
