title: Why am I getting error 500.0 in when using IIS Express (significant debug info included)
body: <p>I created a blank MVC 3 application on VS2010 SP1, and set the app to use IIS Express. When I debug, I get error 500.0  (0x80070585)</p>
  
  <p>I am able to succesfuly run the app using the VS dev server</p>
  
  <p>I have set the app directory to Full Permissions for Everyone, just to eliminate all possibility of security issues. I have further verified that IIS express is able to hit the web.config by confirming it using SysInternals ProcMon. ProcMon does <strong>not</strong> show the IISExpress process attempting to read from any other files in my application directory.</p>
  
  <p>I have followed the suggestions in the following question, but it does not give me any better information. <a href="https://stackoverflow.com/questions/4416068/http-500-internal-error-iis-websites">HTTP 500 Internal Error - IIS websites</a></p>
  
  <p>No logs are generated in the IISExpress directory in either the Logs or TraceLogs directory, but a log is created in Temp, however it is not very useful.</p>
