How to get terminal window inside Visual Studio 2017 / 2019?

It is now available in VS 2019 version 16.6: https://devblogs.microsoft.com/visualstudio/the-powershell-you-know-and-love-now-with-a-side-of-visual-studio/

However, I still prefer Whack Whack since you can't seem to change the font size.

This is now a native feature in the latest Preview Version (Preview 3)

How can we get that?

The Terminal Window in the video seems to comes from a VS extension Whack Whack Terminal. You can download and install it in your vs2017.

(Note:For vs2017, it should be higher versions than 15.6+)

For more details(usage and settings) please check Adding a terminal window to Visual Studio 2017 or A proper terminal for Visual Studio

Update:

1.After install the extension, ctrl+\ twice, then the terminal window will show at the bottom of vs window. And we can change the layout by draging the window like below:

2.Hope it's what you want. Also we can Go Tools=>Options=>keyboard to change the shortcut setting of this window:

Update:

VS 2019 16.3+ added the terminal window as a preview feature. Thanks for the info from Farhad and Platinums! Related info see here.
