How to troubleshoot issues with Windows Forms designer

Background/Situation

While developing a Windows Forms project, an unexpected behavior was observed: some controls don't render, the whole form (designer) doesn't load, or the IDE throws related errors.

Question

How to report such an issue to the Rider team, so that they can investigate and fix the issue? What diagnostic information is needed for troubleshooting?

Answer

To troubleshoot the issue, the team will require:

• Rider logs with the "WinForms" trace scenario enabled (see How to collect Rider logs with Traces).
• If possible (highly appreciated) also share:
  • A recording that demonstrates the issue;
  • A project where the issue occurs;

Share these files in the request you report:

• Report a bug;
• Or contact Rider support;
• Or in any other communications channel;

Upload files to the JetBrains Uploads service and mention the Upload ID, so that the team can access the files you upload.

Or archive the files into .zip, and then attach it to the request/response if the contact form allows it (there might be a size limitation).
