Hi, I'm having some trouble trying to figure out why build tools says that app.xaml path on Xamarin Forms is not supported, I can see in the error list window, file column specifically that it's duplicated somewhere, the path shown is repeated and also the warnings say something about preprocessor tokens being duplicated as well, I don't know where do I have to change those values or if there is any workaround for this issue.

    How long is the path for the Xamarin forms project app.xaml. If you are using windows and the path is greater than 240 characters it can cause problems.
