If you're using Local Native Connection (which is what it looks like from that stack trace calling into the official API), then it's worth noting that by default the Local Native Connection assembly still references the old v2.0.2 MapGuideDotNetApi.dll, which is 32-bit.
Maybe it's worth a try to modify the OSGeo.MapGuide.MaestroAPI.Native project to replace the old MapGuideDotNetApi reference with your 64-bit MapGuide .net assemblies and build that modified project. If not, you should check that you're referencing 64-bit MapGuide .net assemblies (with the 64-bit unmanaged dlls in the same location) - Jackie -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Maestro-3-5-API-Issues-tp7050967p7053635.html Sent from the MapGuide Users mailing list archive at Nabble.com. _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
