Why isn't the Error List in Visual Studio 2017 showing all errors and how do we fix it?

Question

I have two coworkers that just installed Visual Studio 2017. On some solutions, they're not seeing errors in the Error List when they rebuild or run a solution. All of these solutions were originally created in Visual Studio 2015; don't know if that matters. On the Output tab, they can see the errors along with warnings, but when they go to the Error List tab, it says 0 errors. I've found examples of other people having this problem, but can't find any solutions:

How do I get the Error List so it shows errors again?

I experienced something similar, but in my case it was my fault. On the top of the errorlist, there is a combo box. In my case, it was at the state of "Only build", but in order to see all errors, switch it to "Build+IntelliSense". Maybe this simple solution might help some of you. In VisualStudio forums, they recommend you to disable lightweight solution: https://developercommunity.visualstudio.com/content/problem/26498/erorr-list-not-updating.html
