Errors when changing Service reference URL in SDK Silverlight samples

Hey,

When I open the "soapforsilverlight" and change the Service Reference to my CRM server, I can't compile anymore since there's a lot of errors in the SilverlightExtensionMethods.cs.

A lot of them are related to:

Error 7 Instance argument: cannot convert from 'SoapForSilverlightSample.CrmSdk.AttributeCollection' to 'System.Collections.Generic.IList<SoapForSilverlightSample.CrmSdk.KeyValuePair<string,object>>' 

C:\CRM2011JanuarySdk\sdk\samplecode\cs\silverlight\soapforsilverlight\SoapForSilverlightSample\SilverlightExtensionMethods.cs 62 17 SoapForSilverlightSample

any clues on how to get this to Work?
