Visual Studio Console Debug Popup - visual-studio

Question

I've been running some Quickstart samples from IdentityServer4 and found that when I run a web site (e.g. the IdentityServer)... a popup shows up with messages... I am assuming it's either a logger window or the console output... but I have poked around and have no idea how this is done.
Any help?

Answer 1

So... I quickly made a project called test as an example... and in the Properties/launchSettings.json... there were two items under profiles (IIS Express and test)... then when I choose this project there is now, in 2019 at least (maybe I never noticed it before), a new combo box where I can choose between IIS Express and test... when I choose IIS Express it just shows the browser... but when I choose test it shows the browser and a command box with I believe console debugging info.
This maybe be referred to as Self Hosted, but not 100% sure.
