This is because Semantic Kernel supports .NET Framework 4.6.2 but MongoDB C# Driver 3,x requires .NET Framework 4.7.2 or later.

[damieng]

Same cause as #11652

[roji]

Damien Guard (@damieng) wanted to check where we are on this - do you need anything from us?

[damieng]

We've talked at length and supporting 4.6.2 is a no-go for us for a number of previously-stated reasons.

I think if you're okay with the min req for the Semantic Kernel MongoDB driver changing to 4.7.2 then we can submit a PR.

As well as some new features it also has made the test runs a lot more stable on our end.

[roji]

Absolutely - as discussed you're the ones best-placed to make decisions for what you support and what you don't. Definitely feel free to submit a PR for that.
