While trying to debug an ASP.NET MVC project using the recently released VS 2013 Preview I get this message:

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

Please contact the website owners to inform them of this problem.

In Firebug I see this error message:

SecurityError: The operation is insecure

Tried with Google Chrome and IE 11 and the same problem happens.

What is causing this?

Note: I'm on Windows 8.1 and debugging the site using IIS Express at http://localhost:7777

I can debug it just fine using VS 2012.
