I am aware of this tutorials http://wix.tramontana.co.hu/tutorial/getting-started/putting-it-to-use http://www.codeproject.com/KB/install/WixTutorial.aspx
... but I can't find a quick solution for installing web sites and configuring IIS. Is it necessary to manually add each file of the site?
You don't need to add each file manually. Instead, you can use Paraffin to harvest the files needed from your web project.
I configured it so that it is automatically run during a build (local or on the server) by manually modifying the Wix project file to add a BeforeBuild action. Here is an example, you can use this as a starting point.
<Target Name="BeforeBuild">
<!-- Set the WebClient.wxs file as not read-only -->
<Exec Command="attrib -R "$(ProjectDir)WebClient.wxs"" />
<!-- Run paraffin to generate the wix component for the web client. This assumes that web project has already been packaged.
This is automatically done on the build server by setting the property 'DeployOnBuild' to true. -->
<Exec Command="paraffin -update WebClient.wxs -dir ..\RM.Web\obj\$(Platform)\$(Configuration)\Package\PackageTmp\" />
<!-- Set the WebClient.wxs file back as read-only -->
<Exec Command="attrib +R "$(ProjectDir)WebClient.wxs"" />
</Target>
