Can VS2012 build a proxy in a PCL project to consume a WCF service for SP2010? We add a reference (old school works everywhere else) but once we make calls, for instance GetListsCollectionAsync(), we get all sorts of errors. When we build the proxy, VS gives a warning:
Service proxy generation failed. Proxy requires type 'System.Xml.Linq.XElement' which is not supported in portable libraries
Has anyone successfully subscribed to a SharePoint WCF using a portable class library? The same stuff works fine in .net 4.5 class libraries and in metro libraries. Only portable ones give us this problem. We have win 7 and win 8 devices in the mix - so PCL would be a really good fit.
