@Kevin-Mok That's a different issue. Can you create a separate ticket for it, and describe how you're launching the installer and what terminal you use?

@tstaples This seems to happen if you don't have Visual Studio 2017, since code analyzers are a pretty new feature.

I was compiling with VS2017 though. Perhaps I need to update though? What version are you running?

@tstaples I have VS Community 2017 15.6.6. Do you have an older version?

Yeah I was using VS Community 2017 15.1. Updating fixed it.

@mralbobo Thanks! I expanded your addition a bit.

Just throwing this out there, but it might be worth mentioning this in the migration guide.
(I added a quick mention to it)
