Code Snippet

using (OCUserProfileService.UserProfileServiceSoapClient service =
new TestAndDestroy.OCUserProfileService.UserProfileServiceSoapClient(GetWcfBinding())) {

                    service.ClientCredentials.Windows.AllowedImpersonationLevel = TokenImpersonationLevel.Impersonation;

                    PropertyData[] properties = service.GetUserProfileByName("domain\\user.name");

                    foreach (PropertyData p in properties) {
                        Console.WriteLine(p.Name);
                        Console.WriteLine(p.Values);
                    }

produces....
The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://microsoft.com/webservices/SharePointPortalServer/UserProfileService:GetUserProfileByNameResponse. The InnerException message was 'Error in line 1 position 392. 'Element' 'IsPrivacyChanged' from namespace 'http://microsoft.com/webservices/SharePointPortalServer/UserProfileService' is not expected. Expecting element 'Name | Privacy'.'. Please see InnerException for more details.

I'm totally stumped, any ideas???

The good news is I can confirm this behavior. The bad news is I'm also looking for a fix. =(

I was able to reproduce as well. The WSDL doesn't match the shape of the XML that is being returned from SharePoint. The short-term fix is to change the generated proxy code to match the shape of what SharePoint is actually returning (versus what is exposed in its WSDL). The actual shape of the message is:

Code Snippet

<s:complexType name="PropertyData">

<s:sequence>

<s:element minOccurs="1" maxOccurs="1" name="IsPrivacyChanged" type="s:boolean" />

<s:element minOccurs="1" maxOccurs="1" name="IsValueChanged" type="s:boolean" />

<s:element minOccurs="0" maxOccurs="1" name="Name" type="s:string" />

<s:element minOccurs="1" maxOccurs="1" name="Privacy" type="s0:Privacy" />

<s:element minOccurs="0" maxOccurs="1" name="Values" type="s0:ArrayOfValueData" />

</< FONT></s:sequence>

</< FONT></s:complexType>

Notice that the IsPrivacyChanged and IsValueChanged elements need to appear first in the sequence. For instance, you can change the generated WCF proxy type for the PropertyData class to look like the following:

Hi kirke!

I have replace my PropertyData class, by your code, but it not help me.

Now I have other similar error:
"Error in line 1 position 11015. 'Element' 'Privacy' from namespace 'http://microsoft.com/webservices/SharePointPortalServer/UserProfileService' is not expected. Expecting element 'Name | Group | Email | Title | Url | IsInWorkGroup'."

Unfortunately, I was never successful at calling SharePoint web services by adding a service reference. You can add a regular .net 2.0 service reference by clicking on the "Advanced" button when adding a service reference and then clicking on "Add Web Reference"

You need to add the SharePoint Service as normal ASMX service reference i.e; Web Reference from the Add Service Reference wizard and it should be always basicHttpBinding, otherwise it wont work.

Thanks for the response Steve. That option is not available in my Advanced dialog. Must have something to do with this being a Silverlight project.

Ok Silverlight is different. Chakkaradeep was pointing the correct way. When you add a service reference just point to the ASMX url, like http://localhost/sitename/_vti_bin/lists.asmx and then open up your ServiceReferences.ClientConfig file in your project and make sure it is using basicHttpBinding like below

<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="ListsSoap" maxBufferSize="2147483647"
                    maxReceivedMessageSize="2147483647">
                    <security mode="None" />
                </binding>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost/_vti_bin/lists.asmx"
                binding="basicHttpBinding" bindingConfiguration="ListsSoap"
                contract="ListsClient.ListsSoap" name="ListsSoap" />
        </client>
    </system.serviceModel>
</configuration>

Then you can create the web service proxy like so and call the methods on it asynchronously:

ListsSoap ls = new ListsSoap("ListsSoap", "http://localhost/sitename/_vti_bin/lists.asmx);

Thanks guys. The issue appears t be with the UserProfileService. In your examples you are using Lists.asmx. I am calling UserProfileService.asmx. It appears that the XML result is malformed. It works in 2.0 applications but not 3.5 applications.

I cannot mark your advice as an answer because it still does not work for the scenario that started the thread (though your advice may help others using the Lists.asmx or other SharePoint web service).

I'll write my own WCF compliant service and use that.

Thanks!
