Is there an equivalent package for .NET Core?

Really trying to find how to connect in Amazon Neptune from an AWS Lambda outside the VPC, we created a network balancer but can't seem to find a way to sign requests from our .NET Core application.

The issue names no source files, tests, or entry points. Start by reviewing the repository's Java client and AWS Signature Version 4 scope, then determine the requirements for a .NET Core equivalent in the stated Lambda and Neptune setup; done requires a clearly scoped, supported solution.
