CS0016 & Temporary ASP.NET Files Errors…）

I have been seeing many people with issues related to the “Temporary ASP.NET Files””

CS0016:
Could not write to output file
'c:"WINDOWS"Microsoft.NET"Framework"v1.1.4322"Temporary ASP.NET
Files"application"…….' . The directory name is invalid.

You could also be getting an “Access Denied” message.

Here is a collection of fixes which I have found:

You might also need to set the correct security permissions on the folder for your user (aspnet, networkservice or other)

When all else fails I have also attempted to simply delete Temporary ASP.NET Files"*.*, all sub folders and files. You might need to IISReset in order to release the files. Also
consider reading the index server stuff above incase it has the files
locked.  Perform the iisreset, and worst case scenario reboot and try
again!
