There's a lot of people on here trying to trade for Foligno, but regardless of the value here, I'm just curious if there's one example besides Matthew Tkachuk of a player getting traded after signing an extension. Because that one was an obvious sign and trade. Offers for Foligno have been all over the place, but I just don't see any realistic world he's traded. He also has a NMC, so that just adds to that thought...

Tkachuk didn't get traded after signing a in\mid season extention.
Calgary and Florida did a sign and trade, Calgary ''signed him'' because they could give him the 8yrs and than Florida acquired him but, Tkachuk wouldn't have signed the deal without the trade in place. If that's the standard for signing before being traded, Severson did that last year too. I'm not gonna deep dive but, it's fairly common.

Foligno's case is different though he signed in-season, saying he wants to stay and the team wants him to stay, those types of trades are rare but, I'm guessing it has happened a few times. (I.e. signing the contract with one GM and a mid-season firing, new GM has a different view of the team and trades the player)
I would guess that Minny doesn't trade him though, sends a bad message about respect for future signings and contract negotiations

Foligno was one of my top targets for the offseason, alot of people thought I was crazy. He would make this team so much better right now.

A deal like this Middleton and foligno would need a bit more from the red wings to Minnesota. Don’t get me wrong the wild can use the cap space and have defenders coming up to make up for Middleton but those 2 are a combo of size and go power every team needs, so there would need to be a bit more added.

I’d be pretty comfortable adding a pick or a defense prospect to something like this. The Wings desperately need the things you mentioned there, and these guys fit the timeline where our prospects who’d add the same quality (Kasper, Mazur, etc) will be on the team.

Jack Campbell when LA traded him to Toronto is the only case I can think of where a player signed an extension and then was traded before it kicked in. He signed his deal September 7th, 2019, was traded February 5th, 2020 to the Leafs, and his extension kicked in July 1st 2020.
