Hi @dubstab96 ,
Thanks for reaching out. Can you provide some more context, e.g. what specific icons and with what controls you use them?
Im using mostly IconButton and IconPictureBox in my application. Sometimes there are no icons showing, sometimes some shows and some others not and sometimes everything works just fine. Here are some screenshots of different runs.
Successfull run:
Not successfull run:
I don't know if this is kind of VStudio Debugger problem, seems to happens on builded app also. I might have to mention that i also use MaterialSkin controls (https://github.com/IgnaceMaes/MaterialSkin) and in one on thousands an exeption will occur on startup, stating that "Roboto" font does not support style "Regular".
Looks cool! There were some recent fixes regarding WinForms font selection, e.g. by explicitly setting the FontStyle, cf.:
Not sure what NuGet-version you are using.
Im using FontAwesome.Sharp version 5.15.3 Seems to be the latest.
Ok, did you tree setting the FontStyle explicitly?
Yes, just found out that it was set to Auto. I will set every control with the right IconFont and i will let you know if the problem is solved :) Thank you very much
After setting the IconFont property of some of the controls an ArgumentNullExeption was thrown
Again this exeption is not thrown every time application start. After two retries the app started just fine.
Ok, this looks like a problem with initialization order, i.e. fonts are not yet fully loaded. The IconFont-setter should be this line, cf.:
Could you provide the whole stack-trace here?
i'm not sure if this is what you need.

Looks like this line here, cf.:
Yes, this should help.
Just for completeness: Which .NET/Core- and OS-version are you using?
Will also check for possible side-effects with https://github.com/IgnaceMaes/MaterialSkin
Not sure when i can promise you feedback on this.
Would you be able or willing to submit a pull request?
I am using .NET Version 4.8.04084 Windows 10 build 19042.867
I am sorry but this project is taking the 110% out of me. Maybe some time in the future :)
Thank you for your help, Always happy to hear from you.
Ok, no problem. Target system is the same i guess, i.e Win10, net48?
Yes, I tried to remove completely every reference of the MaterialSkin and after two whole days, no problem occured. Everything works just fine. Seems that there are side effects when MaterialSkin and Fontawesome.Sharp is loaded
Hi @dubstab96, ok for you to close the issue then?
Of course. Thank you very much for your help
I have a WinForms application that i am building with C# and sometimes the icons is not showing at all. After an app restart maybe they will.
