Block commenting VB/VB.NET code

Question

How to comment multiple lines of code/block of code in VB?

Answer 1

VB doesn't have such a construct at the language level. It has single line comments using apostrophe character:

' hello world
' this is a comment
Rem this is also a comment

However, Visual Studio has a functionality to automate this task. Select the lines you want and press Ctrl+K+C for commenting and Ctrl+K+U for uncommenting (General Development Settings shortcuts, look at the "Edit -> Advanced" menu while selecting some code to see the shortcuts).
