CS0016: Could not write to output file up vote 11 down vote favorite 1 In Brief When I attempt to browse my website, I get the following error message: CS0016: Could not write to output file 'c:\Windows\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files\www\xxx\yyy\zzz\a.b.dll' - 'The directory name is invalid' In Detail I have two web-sites on my Development PC (fictitious names): Web2 - this is written in ASP.NET could not write to output file access is denied visual studio using .NET 3.5 and runs in an AppPool that addresses the v2.0 .NET framework and runs in an Integrated mode. This is developed using Visual Studio 2010 Web4 - this is written in ASP.NET using .NET 4.5 and runs in an AppPool that addresses the v4.0 .NET framework and runs in an Integrated mode. This is developed using Visual Studio 2012. Recently, I've been working in VS2012 on Web4 almost constantly and it works fine, however the other day I tried to run Web2 and got the exception displayed above. Bizarrely, part of the path (which I replaced above with letters "zzz") appear to point to a German language path, since it's "\de-DE\" - I'm not operating in German, so I've no idea where it got this idea from. One thing that is almost certainly un-related, but for some unknown reason I feel it's important to mention: I was using the Performance Analysis tool in Visual Studio 2012 the day before this problem first appeared and I don't know if this might have made some changes to my computer...?? Attempted fixes There are quite a few threads regarding this on

or Impersonating thread identity required NTFS access to the resource. The reason I like working here in PSS is because you get to work on issues which will blow your mind (EVERYDAY). http://stackoverflow.com/questions/15119880/compilation-error-cs0016-could-not-write-to-output-file Most customers would have already Googled for a solution and tried an extensive list of things trying to fix the issue. If they haven't already done that, then they are calling because the WebSite is down and the business impact $$$$$$$$ is "HUGE". In this case the customer was of the former type. He had tried everything to fix the issue but to no avail. https://blogs.msdn.microsoft.com/viag/2007/02/08/compiler-error-message-cs0016-could-not-write-to-output-file-cwindowsmicrosoft-netframeworkv1-1-4322temporary-asp-net-filesmyappfadda49ebbdb0b87eqdatzch-dll-access-is-denied/ To give you a little background on the issue, the Web Server was a Windows 2003 SP1 server(IIS 6.0) running an ASP.NET WebService. The App used to work fine until it threw the above error. According to the customer, the only way to recover from the problem was to repeatedely reboot the machine and the error would go away. I had never heard of anything like this before. Neither have the 3 Engineers who worked on this issue before engaging me to have a go at the problem heard of anything like this. The typical way to troubleshoot this problem would be to verify that all the permissions and policies were in place as per the knowledge base article Process and request identity in ASP.NET: http://support.microsoft.com/kb/317012 . The AppPool identity was the default "Network Service" account. After verifying kb317012 a dozen times we were still getting the error. The bizzare part was that "Network Service" account had Full Control on "c:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files" folder but running Filemon would still show Access Denied for the "Network Service" account on "c:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files" folder. The Engineers had tried various way to troubleshoot the problem. They tri

recieved an error stating that the compiler couldn't write to the "Temporary ASP.NET Files" folder because the path was invalid. Eventually I tracked down the resolution : http://support.microsoft.com/default.aspx?scid=kb;en-us;825791 Cause The system TEMP and TMP variables point to a folder that does not exist. The compiler generates temporary files in the folder where the TEMP and the TMP variables point to before the files are copied to the Temporary ASP.NET Files folder. However, the folder where the system variables point to is deleted when you restart the computer. Therefore, the compiler cannot generate the temporary files. Resolution Create a temporary folder under , and then name it Temp. Grant full permissions on the Temp folder to the NETWORK SERVICE user account. Right-click My Computer, and then click Properties. On the Advanced tab, click Environment Variables. Select the TEMP variable under System variables, and then click Edit. Type \TEMP in the Variable Value box, and then click OK. Repeat last two steps to edit the TMP variable. Click OK two times. Click Start, and then click Run. To reset Internet Information Services (IIS), type iisreset on the command prompt. Note If the error message that is mentioned in the "Symptoms" section of this article persists, restart the computer.
