So you can easily just change a build flag without touching any XAML or creating a new project and everything just works?

I was quite explicit

There are just a few differences in the APIs, but that is about it.

Meaning that of course some changes are required.

It is like when one changes SQL queries among RDBMS servers, of course some things change, but one doesn't have to throw out all the SQL knowledge out the window just because of that.
