In VB, I would change the name of controls often. I'd start with textBox1 and later change it to txtInput or whatever. C# doesn't like this. When I do this, I get errors that the control with the old name is missing.
Change the name on the fly without the errors. Do I do a global search and replace or a rename or what? What is the easiest way to do this?
The easiest way is to refactor the names, refactoring makes sure that in case you have used the name already, that it also updates the places where it founds the old name and replaces it with the new name.
