Hello, I'm having some problems with the fact of some Layer class not being marked as Serializable.
for instance:
System.Runtime.Serialization.SerializationException: Type 'ThinkGeo.MapSuite.Core.GeoTiffRasterLayer' in Assembly 'MapSuiteCore, Version=4.0.0.0, Culture=neutral, PublicKeyToken=0828af5241fb4207' is not marked as serializable.
But I also found it in HeatLayer, and some others.
