How can I do WCF Non-HTTP Activation with .Net 4?

I have a .Net 3.51 service which uses Non-HTTP Acti开发者_C百科vation. This works fine. I want to convert it to .Net 4.

In Windows 7, if you go to Control Panel, Add Remove Programs, Turn Windows Features on or off, there is a "Microsoft .NET Framework 3.5.1, WCF Non HTTP Activation" item.

How would I do this for .Net 4 ?

In fact turning it on for 3.5.1 turns it on for 4 too. I got exceptions because the appdomain reverted to .net 2. The non http activation works fine.

Posting what worked for me since there's a few conflicting or outdated instruction sets out there.

Select Programs and Features.

Click Turn Windows Components on or Off.

Expand the Microsoft .NET Framework 3.0 node and check the Windows Communication Foundation Non-HTTP Activation feature.

I just did it for 4.5:
