I ‘m trying to capture trace for argument named “arg1”
and i use this tracking profile
private MyTrace CreateTrace()
{
string all="*"
MyTrace trace = new MyTrace();
trace.TrackingProfile = new TrackingProfile()
{
ImplementationVisibility = ImplementationVisibility.All,
Name = "CustomTrackingProfile",
Queries =
{
new CustomTrackingQuery()
{
Name = all,
ActivityName = all
},
new WorkflowInstanceQuery()
{
// Limit workflow instance tracking records for started and completed workflow states
States = {WorkflowInstanceStates.Started, WorkflowInstanceStates.Completed }
},
ActivityStateQuery query = new ActivityStateQuery()
new ActivityStateQuery()
{
ActivityName = "*",
States = { ActivityStates.Executing ,ActivityStates.Closed},
Arguments={"arg1"}
}
}
};
return trace;
}
Activity to trace : (It’s very simple arg1=”value”)

When i execute activity(Workflow1) , i recive this trace ouput:

Why argument (arg1) only notify changed when Workflow1 is closed?
Whats happend with assing arg1=”value”? I think it must notify argument was changed
Use the tracking participant created by Ron Jacobs. It’s really easy to query after the activity has run because it has structured results and you’ll be able to pick up that argument at every stage actually. It actually uses the Microsoft.Activities.UnitTesting framework for the participant. This participant can actually track child workflows at the same time as well!
Here are some blog articles where Ron explains how to use it.

EDITED
I am editing this to clarify that if you must get more frequent updates you’ll need to track a variable and not the argument. So, set the value of a variable to that of the argument, and then if you need to before leaving the workflow, set the value of the argument to that of the variable but setting the InArgument at the end of the workflow is really of none effect because nobody is going to be using it (at least I’m assuming).
