I am in the process of adding support for more map file formats in our application which uses ArcGISRuntime v100.0. I am currently trying to do this by starting a LocalServer and adding a LocalMapService to it. The idea is that a client can convert from a number of formats into a .mpk file in ArcMAP, which we can then add to our application by using the LocalServer. However, I don't have a lot of experience in using ArcMAP, so I am spending a lot of time trying to create som test data. Is there somewhere I can download some test data from, that could help me test my implementation of LocalMapService?
