Migrate to a supported (stable) .NET LTS version?

[mochsner]

Wanted to reach out to the community to see if anyone's actively aiming to (or using) the basis of this project in a production system, and whether there'd be an interest either from anyone else (@tompaana or otherwise) in the community on a collaborative effort to upgrade to a later .NET (LTS) version. I see a PR for netcore 3.1 from @muratkakun 2 years ago that still wasn't merged in, somehow... any reason why not @tompaana ?)

The fact that such an interestingly useful project hasn't been touched in ~3 years definitely has sparked some concerns over Microsoft's support of this product (BotFramework) for me going forward -- are they looking to go a different direction (e.g. Health Bot or Power Virtual Framework?) because it's more profitable to advertise to business folks and say they don't need a "developer"?. If BotFramework is really here to stay, I think this repository could use some more activity and updates... it enables a lot of what is already natively available on those other offerings (e.g. hand-off to Teams for healthbot, and power-virtual-agents )

I'm not working on BotFramework long-term, but was put on a project in it a couple days ago, and I can't tell whether this (BotFramework) is something really worth investing a lot of time into. But if there is, I'd love to get on a later version.
