How to see workflow variables values when debugging WF 4 Workflow Activity

Question

I am new to Workflow Foundation and I am unable to see what value the Activity variable is being set to. I have set a break point in the activity but the locals window does not show anything.

How do I check the Activity variable's values when debugging?

Answer 1

What is the thing you are you calling "Activity variable"? Are you referring to the In/Out Arguments of an Activity?

Answer 2

You can view the value of an "In" argument by viewing the activity in its XAML (code) definition and hovering over the argument's attribute value when the debugger is paused. You can also dig around inside the private properties of the DataContext member of the activity's execution Context to see all the information about the Variables. Sadly, it is far from intuitive, but sometimes gives you enough information to figure out what's happening for yourself.
