.NET Core portable assemblies package.config generator. Convert* your .NET Standard project to .NET Core.

portable_packages.py

# Copy your .NET standard project files to an empty .NET core project and build it
# Save the error log to a file (eg. builderrors.log)
#
# Usage:
# python portable_packages.py builderrors.log packages.config
#
# NOTE: NOT ALL ASSEMBLIES IN .NET STANDARD ARE SUPPORTED BY .NET CORE
