dotnet/runtime is failing to restore from internal azdo feeds

• Is this issue blocking: no
• Is this issue causing unreasonable pain: yes

@safern reported that even after updating the version of .Net SDK to a recent one the dotnet/runtime builds are still failing to restore from internal azdo feeds. Sample build is here.

Error message:

@riarenas - we need to do a RCA on this. Perhaps open another issue? This’ll come back… 😦

Did the changes help?

Yeah, the changes fixed the problem.

I guess whenever 3.1.200 is available we could bump our global.json to that and we can then remove the workarounds.
