How to comment multiple lines in visual studio using "//" instead of "/*"

When using the comment shortcut Ctrl+K+C it comments like this:

/*totaly();
legit.code()*/

This is very inconvenience when you what to uncomment just part of the code. Is there a way to comment multiple lines at the same time like this?

//totaly();
//legit.code()

I am using normal Visual Studio, not VS Code.
