I have a SP2013 Provider-hosted app with DevExpress controls that was working fine until just recently. I am getting the following error when I try to F5 DEBUG:
"Error occurred in deployment step 'Install app for SharePoint': The file exists."
The app actually installs and executes but the debugger detaches very quickly plus it is prompting with the nagging aforementioned message. There are no AppUninstall / AppInstall / AppUpgraded events being handled.
Thanks in advance.
