When I build in Visual Studio the site and then I publish to the IIS,Could you please give more detail to the steps you take?
when I start the site with the explorer I'm not asked about the possibility to choose the razor-html-xslt configuration
Is it normal?
In general, you can have either an initialized site (where you have already completed the initial setup wizard - choosing the starter site, languages, admin's password etc),
or a non-initialized site (where you haven't run the wizard yet).
So you'll get whatever you publish to IIS. If you run your non-initialized website from Visual Studion (say, on IIS Express or on ASP.NET Dev Server) and complete the wizard and then publish it to IIS, you'll get an initialized website and you won't have an option of selecting the site type (architecture).
