Authentication issue when debugging in VS2013 - iis express

Question

I'm trying to pick up the windows username when debugging in Visual Studio 2013. I am simply using:

httpcontext.current.user.identity.name

If I run this on my Dev Server it works fine, if I run it in debug mode on any previous version of Visual Studio it also works fine.

My problems is - If i run this on visual studio 2013 I get an empty string.

My web config is as follows.

<system.web>
    <authentication mode="Windows"/>
    <identity impersonate="false"/>
    <authorization>
       <allow users="*"/>
    </authorization>
    <compilation debug="true" strict="false" explicit="true" targetFramework="4.0"/>
    <customErrors mode="Off"/>
</system.web>

As I was researching this I found my answer, but can't find the answer on the internet, so I thought I'd share this:

I fixed my issue by modifying my applicationhost.config file. My file was saved in the "\My Documents\IISExpress\config" folder.

It seems that VS2013 was ignoring my web.config file and applying different authentication methods.

I had to modify this portion of the file to look like the below. In truth, I only modified the anonymousAuthentication to be false and the windowsAuthentication mode to true.

<authentication>

  <anonymousAuthentication enabled="false" userName="" />

  <basicAuthentication enabled="false" />

  <clientCertificateMappingAuthentication enabled="false" />

  <digestAuthentication enabled="false" />

  <iisClientCertificateMappingAuthentication enabled="false">
  </iisClientCertificateMappingAuthentication>

  <windowsAuthentication enabled="true">
    <providers>
      <add value="Negotiate" />
      <add value="NTLM" />
    </providers>
  </windowsAuthentication>

</authentication>
