The WixBA.Run() method calls the Dispatcher.Run(). The dispatcher is the message pump for the UI. Without the message pump, the WPF UI won't do respond (even to redraws <smile/>). So, for the WixBA, it needs to run this way.
If you do not have a UI then you technically can do everything via the callbacks. It's actually a pretty cool way to run but you really have to think asynchronously and catch all the potential "exit points" so that Engine.Quit() gets called eventually. Note: Engine.Quit() tells the Burn engine to exit it's processing loop. The process starts shutting down from there. You cannot callback to the engine after calling Quit(). I remember a bug the Visual Studio guys were saying was Burn's fault because they called Engine.Quit() then tried to Log a message. The log was closed and threw an exception so they blamed it on me. <smile/> Don't call any Engine methods after Quit().
