I have a complex set of add-in's that we need to run in ArcMap, ArcServer, and ArcGIS Explorer for Desktop. We are experimenting with changing from the old Web Reference service connection to a WCF Service Reference connection.
When I try to create the client it cannot find the configuration settings to create the client. When I add just the URI to the embedded Settings.settings file, and create an EndpointAddress and Binding object to pass to the client, I get a client but my first attempt to access the server fails.
So how do I access the WCF service configuration data from inside an ArcMap Addin?
Properties.Settings.Default.<yourSettingName>
should work.
