System.Web.HttpException (0x80004005): The file '/Views/Shared/_Layou.cshtml' has not been pre-compiled, and cannot be requested.

Hello,

I have a MVC site (mvc 5.2.3.0 version) installed on a Windows Server 2012 standard, that is working properly for over a year. The last 2 months I have faced repeatedly the following issue.

I have deployed changes and the site is working perfectly. I should mention that I publish the site pre-compiled. Also the application pool is set to "Always running", so that there is no loading time. After a week (5-7 days) it crushes without having changed (I have validated that there is nothing changed) with the following error:

System.Web.HttpException (0x80004005): The file '/Views/Shared/_Layout.cshtml' has not been pre-compiled, and cannot be requested.

I have tried several things to restore it, but nothing is working, change the user to the application pool, restart the machine, IIS and it is major that the site should not crush. So the only way I have found to recover is to rebuild it and redeploy it, the same source code, the dlls are the same, nothing is missing or corrupted.

I suspect after searching for this, that there is a problem with my mvc dll version. I read that nuget packages might come with updates and that might not always load from the site's folder, so that could make an issue if the downloaded version does not apply to mvc dll in my folder. Could that be the case and if so how can I solve it? (I ask here because all the errors I find is during deploy but in my case deploy solves my problem so I am kind of stuck an how can I solve this?)
