Windows 8 App using COM dlls of Sharepoint gives error "Cannot resolve Assembly or Windows Metadata file 'System.Web.Services.dll'"?

Question

I have created a sample app using Windows 8 C# XAML to get site info of SharePoint 2010 using COM Dlls. I have added reference of:

1. C:\Program Files\Common Files\microsoft shared\SharePoint Client\Microsoft.SharePoint.Client.dll
2. C:\Program Files\Common Files\microsoft shared\SharePoint Client\Microsoft.SharePoint.Client.Runtime.dll

but when I build the project it gives me following error:

Error1: Cannot resolve Assembly or Windows Metadata file 'System.Web.Services.dll' E:\Windows 8 And Sharepoint Example\SharePointCOMApp\SharePointCOMApp\SharePointCOMApp.csproj

Error2: Type universe cannot resolve assembly: System.Web.Services, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a. SharePointCOMApp

How can i resolve this?

Answer 1

As far as I remember to my experiences with W8 vs. SP 2013 / O365, Managed Client Object Model assemblies (like Microsoft.SharePoint.Client.dll) cannot be directly referenced from a Windows Store App. Include your code into a wrapper class implemented as Class Library (Windows Store Apps), and reference this one from your Windows Store App.

I suspect you are targeting the wrong version of the .Net framework - you need the full framework and not the Client Profile.
