Tonight, when trying to use Friends League's latest social sharing SDK, the official demo doesn't make much of a change, it removes the sharing of pairs, Facebook and Twitter. And then after the operation has been an error:
{System.IO.FileLoadException:Could not load file or assembly ' System.Xml.XPath, version=4.0.0.0, Culture=neutral, Publickeytoken=31bf3856ad364e35 ' or one of its dependencies. The located assembly ' s manifest definition does not match the assembly reference. (Exception from hresult:0x80131040)
File name: ' System.Xml.XPath, version=4.0.0.0, culture=neutral, Publickeytoken=31bf3856ad364e35 '
At System.Windows.Navigation.PageResourceContentLoader.EndLoad (IAsyncResult asyncResult)
At System.Windows.Navigation.NavigationService.ContentLoader_BeginLoad_Callback (IAsyncResult result)}
The HTML Agility Pack and the friend League share SDK obtained by NuGet were used in the project.
The same error was found: http://ylad.codeplex.com/discussions/430095 (example), because the System.Xml.XPath conflict. Well, he was suggesting that you use the HTML Agility pack instead of using System.Xml.XPath instead of using Linqtoxml instead. I'm not going to do it right now.
Use HTML Agility pack in WP8 to share the System.Xml.XPath load problem with allies in the SDK
