The following code sample demonstrates creating a FlowSwitch(T) node. This example is from the Fault Handling in a Flowchart Activity Using TryCatch sample.

FlowSwitch<string> promoCodeSwitch = new FlowSwitch<string>
    Expression = promo,
    Cases =
       { "Single", singleStep },
       { "MNK", mnkStep },
