@tmat can you point me to the targests in arcade that do sourcelink? I think the easiest way forward is to copy those

Alright, there is no easy path forward. The existing repotoolset targets set out-of-date properties that interfere with sourcelink. We either need to move off of repotoolset entirely or move to...

@davkean pull down the branch from https://github.com/dotnet/project-system/pull/5620 you will get this build error ``` C:\Users\vsagent\.nuget\packages\roslyntools.repotoolset\1.0.0-beta-62705-01\tools\RepositoryInfo.targets(65,5): error : SourceRoot contains duplicate items 'F:\workspace\_work\1\s\' with conflicting metadata 'SourceControl': 'git' and 'Git' [F:\workspace\_work\1\s\setup\ProjectSystemSetup\ProjectSystemSetup.csproj]...

I suppose some careful over-ridding of targets could make things work. I will freely admit that is beyond me. Look forward to seeing the solution

I believe the problem is we never set up a process to track publishing them regularly after balaji left.

@jaredpar can I get another review pass now that I've implemented this running the bootstrap build if there are compiler changes?

verified these changes in https://github.com/dotnet/roslyn/pull/63368
