dotnet core, angular, aspnet framework 4.7.1, 6.8.0 I want to implement a third party widget on the header bar to display a drop down menu with contextual help. How can I pass variables from the current page to the widget? I want the drop down menu to have instructions for the current page. Is there some way I can do this with a publish/subscription model? What's the best way of doing this whilst making minimal changes to Zero code (i.e. reducing merge conflicts from the latest Zero branch)?
