Hi there!
There is no such method. Once application is registered, it takes from a few seconds (on fast systems) to a about a minute (on a slow VM) for an application to start. To wait for an application to start you may simply fire off WebRequest periodically until you get a response. In most cases, however, you won't need to do that, as applications start quite reliably.
