visual studio putting wrong path for virutalDirectory in applicationhost.config?

Question

I recently moved my "My Documents" folder from the C: to the D: drive. This seems to have broken my ability to debug web app in Visual Studio. I'm assuming that visual studio creates entries like the following in applicationhost.config, and I am wondering where the first physicalPath for the root virtualDirectory comes from, as I am fairly certain that is the problem (I've pretty much confirmed that VS creates an entry like the following when a solution is opened):

            <site name="My.Application-Site" id="2">
            <application path="/" applicationPool="Clr4IntegratedAppPool">
                <virtualDirectory path="/" physicalPath="C:\Users\myname\Documents\My Web Sites\My.Application-Site" />
            </application>
            <application path="/My" applicationPool="Clr4IntegratedAppPool">
                <virtualDirectory path="/" physicalPath="D:\repos\MyCheckout\My\My.Application" />
            </application>
            <bindings>
                <binding protocol="http" bindingInformation="*:49924:localhost" />
            </bindings>
        </site>

When I try to run the app in debugger, the browser pops up with an error, the relevant bits of which are below. Notice the path to web.config still uses C:, even though it seems to know the right place for tracelogfiles:

HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.

Config Error       Cannot read configuration file
Config File    \\?\C:\Users\myname\Documents\My Web Sites\My.Application-Site(2)\web.config
Requested URL      http://localhost:50616/My/
Request Tracing Directory      D:\users\myname\My Documents\IISExpress\TraceLogFiles\

So the question is where in Visual Studio (or IIS) is the path for the web.config file determined, and how do I change it. And/or is there some other reason or insight anyone can provide as to why I am getting this 500.19 error?

Another recent change (other than moving My Documents) is I uninstalled a trial of VS Ultimate 2013 and installed VS Pro 2013 -- could that have somehow caused this? Both of changes have been made between the time I was last able to debug the app normally and getting this error.

For someone looking for an answer to "where in Visual Studio (or IIS) is the path for the web.config file determined, and how do I change it" or "I moved my application from its origin folder"

Right-click in Project Properties > Web Tab and Create Virtual Directory buttom.

It all happened when I was developing (and debuging, of course) my application on two different machines, with different paths (and Drives) to the source code managed by git.

Hope it helps
