FontAwesome.Sharp.FormsIconHelper

Hi, I have a problem. One of my testers launched the application and threw this error out of him. Can I ask for help? I'm just learning C #. Thank you

Hi @Alerinos , this seems to be a known issue with legacy net-framework installations. You will probably need to

1. either install a windows KB-update or
2. downgrade the target framework of your app from .net 4.5 -> .net 4.0

Let me know if this helps.

[mkoertgen]

Even better, just use netcoreapp and use multi-targeting. Ship the net40-build to your tester, cf.:

• https://docs.microsoft.com/en-us/dotnet/standard/frameworks#supported-target-frameworks

Hi, unfortunately I can't test this problem again because the tester is on vacation. Do version 4.0 for users below windows 10 and 4.5 for windows 10 users?

[mkoertgen]

Exactly, that should be it.
