In addition to this integration, providing basically nothing more but developer comfort, WiX offers another level of integration, far more advantageous than the first one: the integration of the setup development process with that of the application. Traditionally, setup programs were only written when the main application had already been finished; often even by different developers. This approach requires a tedious and error prone process of collecting information about all the resources making up the application. While the files themselves are usually obvious, registry entries, services and most forms of inter-resource dependencies are often hard to reconstruct in a later stage: if solid development documentation is lacking, the setup developers have to collect all pieces of information from the original developers or try to extract it from the source code.
