Silverlight/WPF Geometry Serialization problem

[BrianBorg]

I have a map control developed with v1.2 and SL3 and a number of Arcobjects webservices used to update spatial data. The webservices accept ESRI geometries as part of the signature.

Recently I have migrated to API v2.0 and SL4. After the migration there seems to be a problem with the geometry serialization. The only webservice that is working is the one that accept Mappoints. Has anyone encountered this problem.

Could you give more info about this serialization issue?

There is many working samples which are serializing polylines and/or polygons:(http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#Lengths, http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#AreasAndLengths, ...).

So the issue is probably depending on your context.
