When debugging on Windows using Internet Information Server, if I took too long to step through what I was debugging, it would time out and I'd have to start over. Talk about anxiety! Lol. This fixes it so you can debug and a comfortable pace:

In app/web/web.config, add

<httpRuntime executionTimeout="360" />

Restart web server.

Might also need to look at max_execution_time in php.ini
