MSI Factory

Fragments are files that can be used to separate a WiX installer into separate files. They can be compiled separately but then linked into one Windows Installer database. You do not generally need to define or add your own fragments in order to create an installer with MSI Factory, however they are supported here if you wish to use them.

MSI Factory makes use of fragments when it generates and builds your project. As well, UI sets make use of fragments to store dialog definitions, error mappings and other data. The fragments that are in the fragments list when you start a new project are put there automatically according to the UI set being used. You should not generally remove fragments from your project unless you put them there yourself.

To add a new fragment file to your project, click the Add button. This will open the Fragment Properties dialog and allow you to include a new fragment in your project. Note that adding a fragment does not merge it into your project file, it just stores a reference to the fragment file on your system and works with it from its source location.
