Font Family Import not Working

[hamzaanjum]

I have added Montserrat font in my project. I have tried every possible way to import the font (all variants as a single resource, so I can use font weight property later on).

<FontFamily x:Key="Montserrat">Montserrat*,Montserrat Alternates*,ms-appx:///Fonts/Montserrat-Regular.ttf#Montserrat</FontFamily>

Only the last method (with the full URI to a single font file) worked, but this isn't something I want. Because when I use this FontFamily in any TextBlock control, then the FontWeight Property is not working anymore.
