hi @kkkmail, thank you for your contribution and sorry for the late reply. I have a request for you: could you rebase your PR to the developer branch? i have a few changes coming too and i will test them together with your changes on that branch before merging into master and updating the nuget package

[kkkmail]

@kMutagene Sure. Give me a day or so, please.

1. Done. I resolved merge conflicts and switched the base to developer as it seems more appropriate.
2. Please, double check lib\Formatting folder as it looks that it is missing proper .gitignore - it pushes DLLs and other stuff, which is not really supposed to be pushed to the repo.
3. Please, feel free to merge the branch when it seems fit.

Thanks.

Thank you.

Im afraid this is working as intended. The files there are a temporary fix for the unfinished transition to .netcore of FSharp.Formatting, the tool we use to build the docs. It is currently not possible to display plotly charts on the generated pages without this custom version i placed in the .lib folder. I hope i can remove them soon.
