I need to consume an external WCF (soap) web service from a web resource via javascript. I've been unsuccessful searching for an example demonstrating how this could be done. Where could find sample code? I don't see anything in the SDK.
You would need to look at the SDK or documentation for the external WCF service. If there isn't any documentation then check out articles about consuming a WCF service with javascript like the one below. The fact that you are calling it from
a CRM web resource shouldn't matter with the exception that the WCF service will need to allow cross domain access assuming it isn't hosted on the CRM server.
