Versioning and Dynamic
Update
var identity = new WorkflowIdentity("My Workflow",
new Version(1, 0, 0, 0));
var workflow = new WorkflowApplication(
new Activity1(), identity);
workflow.Run();
// get the instance data but do not bind to definition
var instance = WorkflowApplication.GetInstance(
instanceId, instanceStore);
// get the definition associated to the identity
var definition = definitions[instance.DefinitionIdentity];
// Create the update map
DynamicUpdateMap map =
DynamicUpdateServices.CreateUpdateMap(definition);
instance = WorkflowApplication.GetInstance(id,
CreateInstanceStore());
application = new WorkflowApplication(targetActivity,
targetIdentity);
// apply the update to the instance
application.Load(instance, this.currentUpdateMap);
