An activity that carries out one of many paths. This activity works similarly to Flow Decision activity, but there are more cases possible to define. Flow Switch <Int32> interprets the result of the given expression and executes activity which matches the key (expression result). By default, paths are labelled Default, Case1, Case2 and so on. Their names have to be changed in the activity properties. You can see the condition when hover mouse over the Flow Switch box.

There is a little triangular mark in the upper-right corner of the activity used in scenario. You can see it hovering mouse over the Switch box. Click on it to make the condition fixed on screen. Click again to make it disappear. To show all conditions in the scenario at once use option Show All Conditions from right-click menu (it works on Flow Decision and both Flow Switch activities). To hide them again use Hide All Conditions.

This activity is meant to be used on the flowchart.
