How to debug dump multiple dumps

Get the Helix payload

Runfo helps get information about helix test runs and azure devops builds. We will use it to download the payload and symbols (recommended version 0.6.4 or later):

dotnet tool install --global runfo
dotnet tool update --global runfo

If prompted, open a new command prompt to pick up the updated PATH.
