Better error message for invalid license in MVC sites
When creating an MVC project and using an invalid or expired license, the mvc application is showing a 503.0 error. There should be a friendly message to guide you to look at the Event Log application. Also, the message in the log should be in Error state instead of Warning to really catch your eyes. An invalid or expired license is preventing the application from running, so for example, if we have cron jobs that look for error types and send emails, we won't catch that error in production if the filter is for Error only.
