To make attribute routing fewer repetitive, route characteristics around the controller are combined with route characteristics on the person steps.

Token substitute may be custom made employing a parameter transformer. A parameter transformer implements IOutboundParameterTransformer and transforms the worth of parameters.

Order of Parameters: Optional parameters ought to be at the end of the route template. If an optional parameter precedes a demanded parameter, the routing could become ambiguous and should not behave as expected.

Routes may be developed by including them on the RouteCollection or by decorating steps or controller with attributes.
