Unable to read the project file 'project.' The Web Application Project proj1 is configured to use IIS

If you ever com up with the error "Unable to read the project file 'project.' The Web Application Project proj1 is configured to use IIS"  edit the .csproj with notepad and change this line :

<WebProjectProperties>
          <UseIIS>True</UseIIS>

To :
<WebProjectProperties>
          <UseIIS>False</UseIIS>
