Are WCF Web services compatible with Sharepoint?

Question

I am trying to place a dataview webPart on a WSS page through Sharepoint designer, consuming a WCF Web service, buth when I place the WSDL of my Web Service, it gives me an error. I migrated the WS to ASP.Net WS and it work perfectly.

The error is related to the Soap envelope. I am using anonymous consumption for now (don't want to add complexity to the task)

Is there something I have to do on WCF to make it 'compatible' with WSS?

Answer 1

It sounds like you are trying to put a WCF web service within SharePoint, right? If that is the case I ran into just this problem recently. You basically have two approaches:

1. Transforming SharePoint's web.config such that it can use full-blown WCF.
2. Write your own HTTP Handler with minimal (if any) changes to the SharePoint web.config.

I have opted for the latter, but go into detail on both at the ThreeWill SharePoint Depth wiki here: Hosting WCF-like REST and JSON Services in SharePoint.

By default OOTB you can't consume a WCF service through SharePoint Designer (afaik).

However "Consume WCF service using Sharepoint Designer" describes a workaround to adjust the datasource so you can read it in SharePoint Designer.
