[Edit] The problem is BitDefender anti virus. I followed the instructions on how to install asp.net 5 beta 8. I was able to install all the necessary files without any problem.

    Start your application from the command prompt with dnx web or dnx-watch web, or select VS2015 todo so.

    Watch the console window for any errors.

    HTTP Error 502.3 - Bad Gateway
    

    You will see these errors only on your screen if you use dnx web.

    I also got this error. and it was caused by a bug in EF. You can get this error if IIS express can't communicate with kestrel anymore because kestrel stop responding.

    Be sure you select the correct dnx version by running dnvm use. to show the list of dnx version available use dnvm list

    :\git\Other\Templates\test\Microsoft.Web.Templates.StarterWeb.AI.IndividualAuth.Tests>dnvm list
