Sporadic error: The file has not been pre-compiled, and cannot be requested : <p>Symptoms: ASP.NET Web Forms website on Azure sporadically crashes and all .aspx page requests fail with this error. The problem seems random and only happens once in a great while. The site may run for months with no issues then out of the blue it will stop serving any .aspx pages and gives the error on every .aspx page request. A restart of the website is the only solution (or redeploy, which causes the same thing).</p>

<p>This was a very difficult problem to debug since it was so sporadic and none of the other answers I found helped, they did not address the problem where the site would deploy and run for long periods of time then crash with this error seemingly randomly. In the end I got some help from Microsoft.</p>
