Cs0016: The Directory Name Is Invalid
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 the internet; some threads end in success where file access permissions have been altered whilst others finish on a somewhat desperate sounding note... I have gone through the process of comparing the NTFS permissions on all relevant sounding directories on my PC with that of a colleagues on whose machine this is still working. Unfortunately, no joy to be had there. I have also un-installed asp.net 2.0 and re-installed it using: C:\Windows\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -u C:\Windows\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -ir and again, no joy

After much wrangling, I setup up the application, but when I navigate to the application, I get an error message: Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. Compiler Error Message: CS0016: Could not write to output file 'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\scom_sibyll\8c0b945e\9329016\App_global.asax.eagmqgcd.dll' -- 'Access is denied. ' I have hunted the web to the best of my ability, and have changed the permissions on the Temporary ASP.NET Files fodler to allow the Network Service account full rights, and done the same with the Temp folder. It copies a number of files before failing, so it has write permissions presumably, so I checked the permissions to read from my source folder, and that is working as well. I additionally noted it's crapping out when it tries to to cache the DLL file
