# Error while running MVC application
Hi all i have been developing an [MVC application](https://www.mindstick.com/forum/12932/how-to-consume-webservices-from-asp-dot-net-mvc-application) in my [remote desktop](https://answers.mindstick.com/qa/50302/how-to-speed-up-your-slow-remote-desktop-connection) . but while executing the [project](https://www.mindstick.com/articles/105927/how-to-excel-at-managing-multiple-projects) im getting the following error . And once i [deleted](https://www.mindstick.com/forum/160487/how-to-remove-the-deleted-git-code-marker-in-scrollbar-in-visual-studio-2022) the abc.dll in my bin the project get executing but why am i getting the following error frequently
**Error 22 Unable to [copy file](https://www.mindstick.com/forum/161620/how-do-you-copy-file-metadata-creation-date-attributes-along-with-the-file) "obj\Debug\abc.dll" to "bin\abc.dll".
