How do I enable IIS during installation?

The following article uses options that are available starting with the Professional edition and project type.

To enable IIS on the target machine during installation you can go in the Prerequisites view and add a Windows Feature bundle.

Select IIS from the available Windows Features list. Filter this list using keywords in the top right search box (Filter Windows Features) or by selecting the corresponding OS from the Target Operating Systems section.
Please note that the IIS Windows Feature may have other dependencies (shown in its tooltip) so when selecting it in the list, its dependencies will be selected as well. When applying a filter, the result Features' dependencies will be listed as well even if their name doesn't match the filter keyword.

Below there is a short video with the above steps.
