# This file is a temporary workaround for internal builds to be able to restore from private AzDO feeds.
# This file should be removed as part of this issue: https://github.com/dotnet/arcade/issues/4080
#
# What the script does is iterate over all package sources in the pointed NuGet.config and add a credential entry
# under <packageSourceCredentials> for each Maestro's managed private feed. Two additional credential 
# entries are also added for the two private static internal feeds: dotnet3-internal and dotnet3-internal-transport.
#
# This script needs to be called in every job that will restore packages and which the base repo has
# private AzDO feeds in the NuGet.config.
#
# See example YAML call for this script below. Note the use of the variable `$(dn-bot-dnceng-artifact-feeds-rw)`
# from the AzureDevOps-Artifact-Feeds-Pats variable group.
