Visual Studio Project Load Error: Invalid Cookie : Parameter name: Cookie -

-

i experiencing problem. has encountered before or know how resolve this. uninstalled iis express , reinstalled 1 project gives me error. others load fine.

enter image description here

the following worked me , didn't require uninstall/reinstall of iis express:

  1. open "applicationhost.config" file located in "%userprofile%\documents\iisexpress\config".
  2. delete "site" nodes located in "sites" node (or perhaps site associated failing project).

upon opening project , starting web application, site node recreated minus customizations may have made it.
