title: ASP.Net Core 1.0 RC2 : What are LAUNCHER_PATH and LAUNCHER_ARGS mentioned in web.config?
body: <p>There are <a href="https://www.youtube.com/watch?v=Vc4nBxcVe7I&amp;list=PL0M0zPgJ3HSftTAAHttA3JQU4vOjXFquF&amp;index=2">breaking changes</a> in ASP.NET 5 RC2 release:</p>
  
  <ul>
  <li>It is rebranded to ASP.NET Core 1.0 (<a href="http://www.hanselman.com/blog/ASPNET5IsDeadIntroducingASPNETCore10AndNETCore10.aspx">ASP.NET 5 is dead</a>)</li>
  <li>Good bye <code>dnvm</code> and <code>dnu</code> command line, they are replaced by <code>dotnet</code></li>
  <li>Various necessary code changes</li>
  </ul>
  
  <p>I am trying to deploy the files generated by <code>dotnet publish</code>. The files structure is different from RC1. I see the following error in the Event Viewer:</p>
  
  <p><code>Failed to start process with commandline '%LAUNCHER_PATH% %LAUNCHER_ARGS%', Error Code = '0x80070002'.</code></p>
  
  <p>These environment variables are mentioned in <code>web.config</code>, which is taken from the <a href="https://docs.asp.net/en/latest/migration/rc1-to-rc2.html">official rc1-to-rc2</a> document.</p>
  
  <pre><code>&lt;configuration&gt;
    &lt;system.webServer&gt;
      &lt;handlers&gt;
        &lt;add name="aspNetCore" path="*" verb="*"
                modules="AspNetCoreModule" resourceType="Unspecified"/&gt;
      &lt;/handlers&gt;
      &lt;aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%"
          stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout"
          forwardWindowsAuthToken="false"/&gt;
    &lt;/system.webServer&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>What are the correct values for <code>%LAUNCHER_PATH%</code> and <code>%LAUNCHER_ARGS%</code> ? These values are not mentioned in their <a href="https://github.com/GuardRex/Docs/blob/master/aspnet/publishing/iis.rst">github publish document</a>. </p>
