Hi @DcraftBg ,
Welcome to Microsoft Q&A forum.
Which version of Visual Studio are you using? Have you tried to update and use the latest version(16.11.15) of VS 2019?
Please also try following suggestions and let me know if it works.
- Right-click your WinForm project node in Solution Explorer > Unload Project > Right-click it again > Reload Project and then check if
View Designer
works. - Open Visual Studio Installer > find Visual Studio 2019 > More > Repair.
- Create a new Windows Forms project and try to target other .NET/.NET Framework and check if it works.
Besides, there should be no need to install a separate extension to show Designer view. And about the missing package folder, not sure, did you install .NET 6 separately?
Best Regards,
Tianyu
