I can\'t solve this problem
I suggest I have to change c:\\Windo
Not the exact same error, but I was lead to this answer since the first half of the error matched. Your applicationhost.config file may simply be read-only. Taking that off solved the error for me. That error calls out the file specifically though, so you should be able to find it easily.
So here are the steps to fix it:
I just went to the directory named in the error and renamed the applicationhost.config and restarted and VS created a new file and ran fine.
I was facing the same issue because of my network password changed.I changed my NetExtendor login password but I have to login in my laptop with old password.
Try these steps to fix this issue:
log into the Computer with whatever password works log into vpn with whatever password works ctl-alt-del to lock the pc then use the new password to unlock it
It worked for me :-)
Thanks!
