Can you try VS 16.5 P1? https://docs.microsoft.com/en-us/visualstudio/releases/2019/release-notes-preview#16.5.0-pre.1.0 As per @OliaG's blog post https://devblogs.microsoft.com/dotnet/updates-to-net-core-windows-forms-designer-in-visual-studio-16-5-preview-1/ VS 16.5 P1 is required for the designer to work with 3.1.

@RussKie we want existing (at least .NET Core 3.0 Windows Forms Desinger to work on v16.4.0 no to install preview of visual studio completely since we are not allowed to use preview version of Visual Studio only extensions - because of ability to unistall them)

Same issue for me and in VS 16.5 P1 I create a new Windows Forms Net Core 3.1 solution and when you right click on the form and select view designer, VS displays message that it is opening the file and never stops and VS Memory increases continuously. After 5 minutes It finally opens with blank Windows Forms (Empty as expected since it is a new solution.) My issue is why does it take so long to open a blank windows Form in the designer.

vs Winform Message

Update: Once the first time the opening file took 5 minutes. Same and other solutions no-longer have this issue.

@SFC-Sarge if you continue to experience problems, please do file a VS Feedback item. That will help give us the telemetry that might help us figure out what the issue is.

After repairing VS 2019 preview it now works loads slow the first time but then is find after the initial load. Just waiting for full functionality to be added. I only use it because WinPE does not support WPF applications, so limited to Windows Forms for workstation provisioning solutions.
