Don’t forget to enable the designer in Tools > Options > Environment > Preview Features.
Many of you may remember that we open-sourced Windows Forms and ported it to .NET Core with .NET Core 3.0. Since then, we’ve been hard at work bringing the Windows Forms designer experience to .NET Core. While we are getting closer to completion, we are continuing work on the designer and plan on bringing more functional and performance improvements in the near future.
How to use the designer
- Install Visual Studio 2019 version 16.6 or Visual Studio 2019 version 16.7 Preview 1.
- To enable the designer in Visual Studio, go to Tools > Options > Environment > Preview Features and select the Use the preview Windows Forms designer for .NET Core apps option.
After completing these steps, once you double-click on your form in the Solution Explorer, the designer will open automatically the same way it is for .NET Framework applications.
Improving the performance is our next goal after we complete the functionality work, so don’t get upset if it’s not as fast as you envisioned while the designer is in the preview, that’s something we will improve in the future.
Currently the new Windows Forms designer works only on Windows 10.
