@jeffhandley we have 114 obsoletion attributes in this repo that link to https://go.microsoft.com/fwlink/?linkid=14202 which is of limited if any relevance to .NET Core. (Same for its sibling topics). Eg it recommends appname.exe.config. I wonder whether we should either remove the links, or generalize the topics. The details of what is obsoleted and why are linked to from there but (a) it doesn't include newer obsoletions and (b) seems to add nothing over the attributes. Just mentioning in case this connects with the other obsoletion work you think about.
