I'm on Visual Studio Code and I'm wondering what the shortcut is for creating documentation in C# for functions, variables, and classes since in VS Studio it's just pressing / three times.

Update Dec 16, 2020

This is now included in the default c# extension as of v1.23.8

You'll have to go to Preferences > Text Editor > Formatting and enable Format on Type

Or add the following in your settings.json file:

{
    "editor.formatOnType": true,
}

Then adding three slashes /// above a member will auto-generate the XML doc comment.
