@isidore can you please update the version and package? I'm ok to leave this without creating a new package and it will simply be included in the next release and I can create my own extension method in my project as a temporary until it's available.

This project is not being actively maintained. Instead consider using Verify. See Migrating from ApprovalTests for more information.

Don't do any special work for me, I'm writing code mostly in Golang nowdays. If I do any more C# I'll switch to use Verify as suggested above. Txs for all the work! cheers, Alan
