            {
                ICrmService service = context.CreateCrmService(true);
                Guid initiatingUserId = context.InitiatingUserId;
                DynamicEntity entity = (DynamicEntity)context.InputParameters[ParameterName.Target];

    Hi.

    You should use following code:

     

    Picklist StageCodePicklist = null;

    if (entity.Properties.Contains("new_stage"))

    StageCodePicklist = (Picklist)entity.Properties["new_stage"];

     

    But in the case new_stage field is not inside of your entity - StageCodePicklist variable will be null.

    Bhaskar,

    Before assignment check for

    if (entity.Properties.Contains("new_stage")) as Andriy mentioned, then you should not get any error
