  Aaaarrggghhhhh.
  
  I tried writing my own plugin after experimenting with the plugin walkthroughs in the CRM 4.0 SDK.  I wrote, signed, compiled, deployed, registered the assembly.  The assembly creates a new Task on update of a Case with all the Case notes in the new Task description.  The registered step is setup as as Post Stage and synchronous, on Update of incident entity.  I'm getting the error below.  I have noooo idea what I'm doing wrong.  I'm very new to writing plugins for CRM.  I can't tell if this is something in my code or my deployment.
  
  Thanks in advance for any help.

  Here is my code.  It was borrowed from some code posted on this newsgroup.  It's written in Delphi.NET (which is now Oxygene (Pascal)).
  
  

   

   

   

  method CopyNotesToCase.Execute(context : IPluginExecutionContext);
  var
     caseId : Guid;
     currentCase : DynamicEntity;
     service : ICrmService;
     req : RetrieveMultipleRequest;
     qe : QueryExpression;
     resp : RetrieveMultipleResponse;
     annotationStrings, taskDescription : StringBuilder;
     t : task;
  begin
  
     caseId := context..OutputParameters[ParameterName.Id] as Guid; 
     currentCase := context.InputParameters[ParameterName.Target] as DynamicEntity;
     service := context.CreateCrmService(true); 
     req := new RetrieveMultipleRequest(); 
  
     qe := new QueryExpression(EntityName.annotation.ToString()); 
     qe.Criteria.AddCondition('objectid', ConditionOperator.Equal, caseId); 
     qe.ColumnSet := new AllColumns(); 
     req.Query := qe; 
     resp := service.Execute(req) as RetrieveMultipleResponse; 
  
     annotationStrings := new StringBuilder(); 
  
     for each a1 : annotation in resp.BusinessEntityCollection.BusinessEntities do 
     begin 
       annotationStrings.AppendLine('<Start> '); 
       annotationStrings.Append(a1.subject); 
       annotationStrings.AppendLine(a1.notetext); 
       annotationStrings.AppendLine(' <End> '); 
     end;
  
     taskDescription := new StringBuilder(); 
     taskDescription.Append(currentCase['title'].ToString()); 
     taskDescription.Append(annotationStrings.ToString()); 
     t := new task(); 
     t.subject := 'SamplePlugin Task for ' + context.PrimaryEntityName + ' , stage = ' + context.Stage.ToString() +' , mode = ' + context.Mode.ToString() + ' , at ' + DateTime.Now.ToString(); 
     t.description := taskDescription.ToString();
  
     service.Create(t);
  end;
