Precompilation related error from an ASP.NET website that is NOT precomplied

Question

I have an ASP.NET website that is XCOPIED to production. I do not publish this website using Visual Studio. I just copy all the aspx and code behind pages to production. There is no publish config file. My production server is running IIS 7.5, integrated pipeline. If I add an App_Code directory to the root directory of the website I get the following error:

The directory /App_Code is not allowed because the application is precompile

Another issue I noticed is that my global.asax file's Application_Start is not being called. (I know this for sure as I Throw an Exception from it)

Answer 1

Somehow a precompiled.config file had made it to production. Don't know how but deleting that file resolved the App_Code directory error and the Application_Start method not being called.
