Cannot serve WCF services in IIS on Windows 8

Question

Seemed to be a no brainer; the WCF service should be enabled using Programs and Features -> Turn Windows features on or off in the Control Panel. Go to .NET Framework Advanced Services -> WCF Services and enable HTTP Activation as described in this blog post on mdsn.

From the command prompt (as admin), you can run:

C:\> DISM /Online /Enable-Feature /FeatureName:WCF-HTTP-Activation
C:\> DISM /Online /Enable-Feature /FeatureName:WCF-HTTP-Activation45

If you get an error then use the below

C:\> DISM /Online /Enable-Feature /all /FeatureName:WCF-HTTP-Activation
C:\> DISM /Online /Enable-Feature /all /FeatureName:WCF-HTTP-Activation45

For Windows Server 2012, the solution is very similar to faester's (see above). From the Server Manager, click on Add roles and features, select the appropriate server, then select Features. Under .NET Framework 4.5 Features, you'll see WCF Services, and under that, you'll find HTTP Activation.

Please do the following two steps on IIS 8.0

Add new MIME type & HttpHandler

1. Extension: .svc, MIME type: application/octet-stream

2. Request path: *.svc, Type: System.ServiceModel.Activation.HttpHandler, Name: svc-Integrated

You can also achieve this by Turning windows feature ON.

This is really the same solution as faester's solution and Bill Moon's, but here's how you do it with PowerShell:

Import-Module Servermanager
Add-WindowsFeature AS-HTTP-Activation

Of course, there's nothing stopping you from calling DISM from PowerShell either.
