.NET Maui font problems

Hi,
I am building an app in .Net Maui. I use custom fonts. They worked very well and suddenly, the program started to crash, saying the fonts uri was not correct. I haven't moved anything. I opened a similar project and it worked well, same configuration. I simply do lot get it.

        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                    fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
                    fonts.AddFont("BLOOMINGS.OTF", "Bloomings");
                    fonts.AddFont("FUTURA BOOK FONT.TTF", "FuturaBook");
                    fonts.AddFont("FUTURA BOOK ITALIC FONT.TTF", "FuturaBookItalic");
                });

#if DEBUG
            builder.Logging.AddDebug();
#endif
          return builder.Build();
        }
    }

        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                    fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
                    fonts.AddFont("BLOOMINGS.OTF", "Bloomings");
                    fonts.AddFont("FUTURA BOOK FONT.TTF", "FuturaBook");
                    fonts.AddFont("FUTURA BOOK ITALIC FONT.TTF", "FuturaBookItalic");
                });

#if DEBUG
            builder.Logging.AddDebug();
#endif
          return builder.Build();
        }
    }

FontFamily="FUTURA BOOK FONT"

leowest•2/15/24, 5:19 PM

u named it FuturaBookItalic when u add it

leowest•2/15/24, 5:19 PM

so you should call FontFamily="FuturaBookItalic"

leowest•2/15/24, 5:20 PM

if you still have issues I would try to rename the otf file to lower case and remove the space to see if it finds it first

EmmanuelOP•2/15/24, 5:58 PM

I use FUTURA BOOK. I tried renaming too. Matched perfectly, without success, with or without spaces.

leowest•2/15/24, 6:08 PM

and have u tried to name the otf file all lower case with no space?

leowest•2/15/24, 6:08 PM

in your solution explorer

leowest•2/15/24, 6:09 PM

I've seen Maui having issue with files with name spaces and upper case letter some times

leowest•2/15/24, 6:09 PM

leowest•2/15/24, 6:12 PM

u can also open the otf/ttf file and use the name inside

leowest•2/15/24, 6:12 PM

because it can sometimes contain multiple types
so here I can use

FontFamily="Eina03-Bold"

FontFamily="Eina03-Bold"

EmmanuelOP•2/15/24, 6:54 PM

Pretty sure I did, will try again and get back to you! Thanks!

EmmanuelOP•2/15/24, 7:23 PM

EmmanuelOP•2/15/24, 7:24 PM

csproj

EmmanuelOP•2/15/24, 7:24 PM

EmmanuelOP•2/15/24, 7:25 PM

EmmanuelOP•2/15/24, 7:25 PM

Somehow it gets stuck on this capital letter thing

EmmanuelOP•2/15/24, 7:25 PM

Even though it's nowhere

EEmmanuel Click to see attachment

leowest•2/15/24, 7:41 PM

u have to remove the other 2 with space on the name

EEmmanuel csproj

leowest•2/15/24, 7:41 PM

from here I mean, otherwise it will still try to load the wrong named fonts and fail

leowest•2/15/24, 7:42 PM

~~wait why they marked as none remove~~

leowest•2/15/24, 7:42 PM

ah no that's right mine is the same thou it should be something else

EmmanuelOP•2/15/24, 7:43 PM

Yeah, they are genuinely nowhere and not referenced either

leowest•2/15/24, 7:43 PM

in the properties its marked as MauiFont right?

EmmanuelOP•2/15/24, 7:43 PM

yep

leowest•2/15/24, 7:43 PM

EEmmanuel Click to see attachment

leowest•2/15/24, 7:44 PM

I mean in here you still have the 2 entries of the files with space on the name

leowest•2/15/24, 7:44 PM

u need to remove those

EmmanuelOP•2/15/24, 7:45 PM

My problem was fixed, but it crashes anyway

EmmanuelOP•2/15/24, 7:46 PM

I do not get the error caused by the fonts though

leowest•2/15/24, 7:46 PM

try to clean the solution

leowest•2/15/24, 7:46 PM

then rebuild

EmmanuelOP•2/15/24, 7:50 PM

The rebuild succeeded but it crashes when i Debug

leowest•2/15/24, 7:51 PM

in xaml how are u calling the font inthe fontfamily

EmmanuelOP•2/15/24, 7:51 PM

EmmanuelOP•2/15/24, 7:51 PM

as I should

EmmanuelOP•2/15/24, 7:52 PM

as far as i know

leowest•2/15/24, 7:52 PM

and does it work if u remove it?

EmmanuelOP•2/15/24, 7:52 PM

nope

leowest•2/15/24, 7:52 PM

and if u comment the 2 entries loading the fonts in the maui cs file

leowest•2/15/24, 7:52 PM

does it work?

EmmanuelOP•2/15/24, 7:53 PM

fonts.AddFont("bloomings.otf", "bloomings");
fonts.AddFont("futurabook.ttf", "futurabook");
fonts.AddFont("futurabookitalic.ttf", "futurabookitalic"); These?

EmmanuelOP•2/15/24, 7:53 PM

crashes too

EmmanuelOP•2/15/24, 7:53 PM

This is insane

EmmanuelOP•2/15/24, 7:53 PM

It worked all afternoon
