@dmitrii-drobotov I suspect based on previous issues the winforms team will ask you to add this to your teams backlog.

@ravipoddar10 - can you help me understand your user scenario for needing to have a designer during runtime? Happy to look into it, just wanting to make sure we enable the right scenario 😄

Hi merriemcgaw

Our team develop a DataEntry product and where user can design our customs control in a predefine form and after that, user build the designer surface generated code.... and that dll is use in runtime where a dataentry operator enter and post the data

sample code (https://learn.microsoft.com/en-us/answers/questions/1187787/private-member-code-generation-and-resize-issue-wi)

@dmitrii-drobotov can your team look into porting these designers so folks can use them at runtime as well?

[16:00:14.298963] warn: [IntegraNet]: Could not resolve type for Microsoft.WinForms.DesignTools.Designers.TableLayoutPanel.TableLayoutPanelDesigner+DesignerTableLayoutControlCollectionCodeDomSerializer.

This seems to look to happen when I open a Form with a TableLayoutPanel
