How to programmatically check WCF Http/Non-Http Activation components?

Question

I need to detect if WCF Http/Non-Http Activation Components is installed during the installation of my product. How can I do so?

Thanks.

Answer 1

For IIS7, check the following Registry Key:

HKEY_LOCAL_MACHINE\Software\Microsoft\InetStp\Components\

For the following components:

• Process Model - ProcessModel
• .NET Environment - NetFxEnvironment
• Configuration APIs - WASConfigurationAPI

From this page: http://learn.iis.net/page.aspx/135/discover-installed-components/

UPDATE: Since the above is true even when the components are not installed, try running this command from the command line:

sc query nettcpactivator

If the service is stopped or does not exist, the WCF Non-HTTP Activation components are likely not installed. To install them, run this command:

pkgmgr /iu: WCF-NonHTTP-Activation
