Hi @Lord Marte , Welcome to Microsoft Q&A,
There are some limitations when using .NET Core to develop WinForms applications under the Linux platform, because WinForms is a desktop application framework for Windows operating systems. Although .NET Core is cross-platform on Linux, WinForms support on non-Windows platforms is implemented through the Wine library, which may cause some compatibility and performance issues.
Currently, Microsoft does not directly provide official support for developing WinForms applications using .NET Core on the Linux platform. WinForms is a GUI framework designed specifically for the Windows platform.
Thanks for your understanding.
Best Regards,
Jiale
