While we commit files to SVN, we encounter that some files need to be deselect from commit list. In fact, we do not want to commit these files to repository always such as dll, pdb or web config files etc. Yet, these files come up with your working files again and again at the same time when your attempt to commit your working files. It may annoy you and you may kill a great deal of your valuable time of development.
To avoid it, we can use a simple feature of SVN which is “Move to changelist -> ignore-on-commit” command. Please see the following image to use the command. I consistently use it and get benefit :)
