#8917 (comment)
Background
#6215
This subitem is focused on making sure that https://aka.ms/msbuild/eventargs / https://learn.microsoft.com/en-us/dotnet/api/microsoft.build.framework.custombuildeventargs contains information about CustomBuildEventArgs deprecation, reasoning, suggested replacements and possibly planned timelines (for Core and for FullFw)
Suggested approach
Put together the required information (based on #8917), create documentation bug https://github.com/dotnet/docs/issues and cooperate with @ghogen on apropriate planning and execution or directly create proposal PR in the doc repo [internal] https://github.com/MicrosoftDocs/visualstudio-docs-pr
