I have a custom solution based on ArcGIS Pro configuration with a custom startup page.
I now want to offer a solution where the user could return to the startup page as an entry of a new project.
I am not sure, if it is a "open startup page"-workflow or it should better be a "close application and begin opening a new application instance".
Could you give me your ideas and how this could be solved?
The start page displayed by your configuration is shown at Application startup and cannot be displayed again.
One idea is to re-use your start page user control and display it from a tab button (OnClick override of the button) in Pro's backstage.
