[mapguide-users] eplot from winform

[Kenneth]

You should fully qualify the name of the map, eg:

Library://Folder/Map.MapDefinition

And use that with the ResourceIdentifier, and ResourceService.Open.

The map.Open() that you are using is a wrapper that allows reading a map 
from the session repository. As you do not have such a map, it won't 
work (you create a new session, that is per default empty).

Beware also that the session map is not the same as the MapDefinition 
(it may have been changed), and the viewer does not store current zoom 
and other properties in this session map. Also, the session map is not 
stored in Xml, but an internal binary format.
