Cannot write configuration file RRS feed

  • Question

  • Hello,

    I have a problem loading up a project I have taken over from some one else. I need some guidance as I can't seem to find the solution. However im not that familiar with .NET or MVS as I once was. The message I get is as follows :-

     

    ---------------------------
    Microsoft Visual Studio
    ---------------------------
    Creation of the virtual directory localhost:49623/ failed with the error: Filename: \\?\C:\Users\firstname.surname\Documents\IISExpress\config\applicationHost.config

    Error: Cannot write configuration file

    However I have checked the permissions and can't see anything obvious. Under guidance from another developer I have also updated :-

    www.nuget.org/

    and

    www.nuget.org/packages/Microsoft.AspNet.Mvc

    I am using a Windows 7 enterprise edition Dell Lattitude laptop. With MVS as follows

  • I see some others have had success by removing encryption on the IISExpress folder and removing the Read Only attribute as well.

    See this post for details.

    Others have had success by doing the following:

    - Run Command Prompt (cmd) in Admin Mode
    - Enter the following command: DISM /Online /Cleanup-image /Restorehealth

    ...as detailed here.

  • Thanks, the removal of encruption on IISExpress folder seems to have sorted me out. I will check out the link you share if I get any more problems. And of course post anything new in forums.asp.net/ as advised earlier.

  • Try to change to another port and see. Sometime the virtual directory in IIS Express might gives you problem.

    To confirm this is an IIS Express issue you can also try to enable your IIS (not IIS Express). Windows 7 enterprise comes with IIS so you can make use of it.
