I'm working in MVC 5 application, and all was working well. but after time of edits and updates, I get a blank page when I try to run or debug it in my local machine.

the blank page come if I working under local IIS or IIS Express or VS development server, all return a blank page.

The response header of the request is 503 Service Unavailable

Solved:

I find the app_offline.htm file in the directory of my application which cause this behavior...

just write for who may get this later, I don't know how/when this file come there.

It may be because the application pool that contains your application is in stopped status. Restart the app pool for your application in IIS as in screenshot below.
