i have created one SequentialWorkflow project and placed IfActivity

and put one codeActivity1 in elsebranch1 and CodeActivity2 in elsebranch2

when i set Rule condition it automatically creates one .rules file.

but from host i need to apply new .rules file?

i have given following code

---------------------

static void ChangeRules(WorkflowInstance Instance)

if (wasChanged)

return;

wasChanged = true;

// Dynamic update of rule

WorkflowChanges workflowchanges = new WorkflowChanges(Instance.GetWorkflowDefinition());

CompositeActivity transient = workflowchanges.TransientWorkflow;

RuleDefinitions ruleDefinitions = (RuleDefinitions)transient.GetValue(RuleDefinitions.RuleDefinitionsProperty);

WorkflowMarkupSerializer serializer = new WorkflowMarkupSerializer();

object obj = serializer.Deserialize(new XmlTextReader("C:\\DynamicRulesWorkflow.rules"));

ruleDefinitions = (RuleDefinitions) obj ;

Console.WriteLine(ruleDefinitions.Conditions[0].ToString());

but it is taking old .rule file

what is the solution for this issue?

Replace the statements:

RuleDefinitions ruleDefinitions = (RuleDefinitions)transient.GetValue(RuleDefinitions.RuleDefinitionsProperty);

ruleDefinitions = (RuleDefinitions) obj ;

with:

transient.SetValue(RuleDefinitions.RuleDefinitionsProperty, obj );
