create-codespace-prebuild.yml

# This workflow adds support for prebuilding Codespaces
# for aspnetcore. For more information on prebuilds,
# see https://docs.github.com/en/codespaces/customizing-your-codespace/prebuilding-codespaces-for-your-project.
# This change prebuilds and pools Codespace instances configured
# for the aspnetcore repo and reduces the amount of time users
# have to wait for a new Codespace to be built and initialized.
