I have an SO Clone IN ASP CORE. How do we feel about building on that?

First of all: Awesome. I’ll look at it tomorrow/on the weekend.

You wondered, why the other post was locked. The reason is that it attracted a lot of discussion that would (probably) not lead to any consensus. Per this post we closed the thread and started a vote. If you have a specific dev-related question, you can (and should) ask it here in the Software Development category.

This is definitely an important point. I think the whole decision kind of depends on this (Ruby for ever/now).
