How to avoid copying a blank line in Visual Studio
Many times I find myself copying some piece of code, then
positioning in a blank line where I want to paste it, and
then mistakenly pressing Ctrl+C again instead of
Ctrl+V. This copies a blank line to the clipboard
overwriting what I had originally copied, so when I finally
manage to paste it, it is not what I wanted.
It
was a great surprise to discover that this behavior is
configurable in Visual Studio:
Just go to
Tools/Options/Text Editor/All Languages, and
uncheck the box where it says
“Apply Cut or Copy commands to blank lines when there is
no selection”.
