Hi @Chris_Venus,
Welcome to the MongoDB Community Forums! Firstly, thanks for raising that ticket, we just haven’t gotten an opportunity to tackle it given other priorities. We are actively improving our LINQv3 provider though, so we’d happily consider any contributions.
The best way to proceed is just what is mentioned in the page you linked. Feel free to raise a Pull Request and our team will take a look at it. The other option is, you can comment on the ticket itself and our team can provide any suggestions as we push that ticket back into triage.
We don’t really have a fixed release cadence for the .NET/C# driver but we have had a release historically every 1-2 months or so as needed. Hope that helps.
Thanks,
Rishit.
