Unable to debug ASP.NET Core RC1 using IIS Express with Visual Studio 2015

When I am trying to debug an ASP.NET Core application in Visual Studio 2015, I am getting following error:

An error occurred attempting to determine the process id of the DNX process hosting your application

It is only happening in Windows 10. I tested with Windows 7 and I did not run into this error.

I am able to run using "web" option in Visual Studio 2015, but the error is happening with IIS Express. When I hit Ctrl+F5 (run without debugging), the browser window opens and just sits there doing nothing (cursor spins forever).

snapshot of toolbar:

The Output -> Debug window is empty, so not sure what is the root cause of this error. Not sure if there is anywhere else I have to look for more error details.

I have

• Microsoft Visual Studio Professional 2015 Version 14.0.25123.00 Update 2
• Microsoft .NET Framework Version 4.6.01038
• Windows 10 pro v1511 OS build 10586.218
• DNVM 1.0.0-rc1-15540
• Microsoft .NET Development Utility Clr-x86-1.0.0-rc1-16609

I even tried a dnvm upgrade, which upgraded dnx to dnx-clr-win-x86.1.0.0-rc1-update2, but error is still occurring.

I tried most of the solutions listed in

An error occurred attempting to determine the process id of the DNX process hosting your application

and

An error occurred attempting to determine the process id of the DNX process hosting your application on clean installed windows 10 + vs2015

and none of them worked.

Here is a simple test application if any one wants to look at it.
