an these are my classes of communication with the host application:
namespace WFReclamation{

ExternalDataExchange]publicinterfaceIRecService{
eventEventHandler<RecEventArgs> RecPriseEnCharge;}}
__
namespace
WFReclamation{
publicclassRecService :IRecService{
publicvoid RaiseRecPriseEnChargeEvent(string RecId,Guid instanceId){
if (RecPriseEnCharge !=null){
RecEventArgs e =newRecEventArgs(instanceId, RecId);RecPriseEnCharge(
this, e); //the error was raised here}
}
#region IRecService Members
publiceventEventHandler<RecEventArgs> RecPriseEnCharge;
}
}
namespace
WFReclamation{
[
Serializable]publicclassRecEventArgs :ExternalDataEventArgs{
privatestring RecIdValue;public RecEventArgs(Guid instanceId,string RecId):
base(instanceId){
RecIdValue = RecId;
}
publicstring RecId{
get {return RecIdValue; }set { RecIdValue =value; }}
}
}

So How Can I resolve this? Thanks .
