When I attempt to get an object from my model I receive this error:
 
"{IdeaBlade.Persistence.PersistenceServerException: Could not load type 'DASvcBos.LookupPatternTypes' from assembly 'DASvcBos, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. ---> System.TypeLoadException: Could not load type 'DASvcBos.LookupPatternTypes' from assembly 'DASvcBos, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

   at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
   at System.Threading.ThreadHelper.ThreadStart()}"
 
From this code:

DASvcBos.DASvcBosDataServiceProxy myBOSDataService =DASvcBos.DASvcBosDataServiceProxy.CreateDataService();

myBOSDataService.CurrentDBConnect =DASvcBos.connectToInstance.Repository;

// Get the current DB instance PM Object

PersistenceManager mPersMgr = myBOSDataService.GetCurrentPersistenceManager();

EntityQuery query;

query = new EntityQuery(typeof(DASvcBos.LookupPatternTypes),DASvcBos.LookupPatternTypes.PatternTypeIDEntityColumn,

EntityQueryOp.IsNotNull, null);

// Next Line fails with the above error! 

EntityList<DASvcBos.LookupPatternTypes> testObject =

mPersMgr.GetEntities<DASvcBos.LookupPatternTypes>(query);

The  object in question was generated by the reverse engineer tool and is untouched.
 
What does this error mean?
 
Kind regards,

I was able to locate the problem so there's no need to respond to this.

Dominique,
 
The issue was that the object model had be re-compiled locally but the recompiled objects were not published out to the WCF Service so the class models did not match.
