Can't open localhost in Microsoft Edge (Project Spartan) in Windows 10 preview

Question

I installed Windows 10 preview and installed IIS.

Open \"http://localhost\" in Project Spartan can\'t connect.

IE has no problem. What\'s the problem?

Answer 1

For the latest build (10158), the following command did it for me:

CheckNetIsolation LoopbackExempt -a -n=Microsoft.MicrosoftEdge_8wekyb3d8bbwe

The trick is to use the Get-AppxPackage PowerShell command to find out the family name of Edge app as vcsjones mentioned.
