See attached sample: open “Form1” in designer, click “Tab 2” and press the DEL key (to delete the tab).

Visual Studio (or the designer process) crashes. Deleting it with the quick actions work.

RibbonDesignerDEL.zip

Attaching another Visual Studio debugger to the “DesignToolsServer.exe” process, I see this exception:

System.NullReferenceException
  HResult=0x80004003
  Message=Object reference not set to an instance of an object.
  Source=C1.Win.Ribbon.6.Design.Server
  StackTrace:

Hi Wolfgang,

Thanks a lot for sharing all the details. We could reproduce the issue on our end. We have reported it to the development team for further investigation and will let you know the updates soon.

[Internal Tracking ID: C1WIN-31395]

I can confirm that it works with .636.

Changelog snippet:

[NET6][NET8] Deleting RibbonTab through the designer was causing Visual Studio to crash. (Jira:C1WIN-31400)

What is the reason that currently all resolved issues are mentioned with numbers different to those that you initially wrote in my forum threads ;-)?

Best regards

Wolfgang

Hi Wolfgang,

Thank you for the confirmation.

Also, there has been a change in our internal workflow, and as a result, the JIRA ID provided to you differs from the one listed in the ChangeLog. From now on, we will update our response with the new JIRA ID after we get the update from the development team.

Thanks, and Best Regards,

Kartik

Thanks for the clarification. It would be very helpful if I could match the issue ids in the changelog with the ids provided here in the forum. So, please either post all related ids in the changelog or post them here ;-).

Best regards
