# These packages are implicitly references by the build process,
# based on the specific project configurations (RIDs, used features, etc.)
# They are always referenced with the same version as the SDK used for building.
# Since we lock nuget dependencies, when these packages are included in the generated
# lock files (deps.nix), every update of SDK required those lock files to be
# updated to reflect the new versions of these packages - otherwise, the build
# would fail due to missing dependencies.
#
# Moving them to a separate list stored alongside the SDK package definitions,
# and implicitly including them along in buildDotnetModule allows us
# to make updating .NET SDK packages a lot easier - we now just update
# the versions of these packages in one place, and all packages that
# use buildDotnetModule continue building with the new .NET version without changes.
#
# Keep in mind that there is no canonical list of these implicitly
# referenced packages - this list was created based on looking into
# the deps.nix files of existing packages, and which dependencies required
# updating after a SDK version bump.
#
# Due to this, make sure to check if new SDK versions introduce any new packages.
# This should not happend in minor or bugfix updates, but probably happens
# with every new major .NET release.
