HTTP Error 500.19 - Internal Server Error - Error Code 0x80070490 - IIS 7.5 ( Works on Azure )

Question

I am executing my code in the Azure emulators. The code I have built is Thinktecture's IdentityServer2. After the emulators start running and everything is ready I get an error when I fire the URL in the browser. There is another SO thread about this issue. But the solutions don't seem to apply to my Web.Config

1. There is no URL rewrite module rule
2. Default website in IIS manager has pass-through authentication. What is this ?
3. Gave full control to users to access wwwroot.
4. virtual folder>basic settings> Connect As > Path credentials has pass-through authentication

What else should I do ?
