Spring.Social WP8 C#

Hi.

I'm having one problem that I can't resolve.

I want to create new share (I think that's the correct word linkedin is using) on linkedin social network (this is the link to do that on the console: http://api.linkedin.com/v1/people/~/shares). I'm using .NET/C# language on Windows Phone 8 platform. Authetication and getting some profile data works great, but there is a problem when I try to do some POST. What is the correct rest operation to do that and how do I format XML object? Obiously the input XML file is the problem, but I can't figure out why.

This is my sample code:

Spring.Http.HttpEntity entity = new Spring.Http.HttpEntity(
"<?xml version=\"1.0\" encoding=\"UTF-8\"?><share><comment>Check out the LinkedIn Share API!</comment><visibility><code>anyone</code></visibility></share>");
entity.Headers.Add("Content-Type", "application/xml");
ILinkedIn linkedInClient = Classes.LinkedIn.Service.GetApi(Classes.LinkedIn.A uthToken, Classes.LinkedIn.AuthSecret);

linkedInClient.RestOperations.PostForObjectAsync<s tring>("/v1/people/~/share", entity, response =>
{
if (response.Error == null)
{
}
});

Classes.LinkedIn.Service.GetApi() method always gets the correct linked client (that's my method for doing that).

This is the error message I get:

POST request for 'https://api.linkedin.com/v1/people/~/share' resulted in 400 - BadRequest (Bad Request).

This is the stack trace if you need it:

at Spring.Rest.Client.Support.DefaultResponseErrorHan dler.HandleError(Uri requestUri, HttpMethod requestMethod, HttpResponseMessage`1 response)
at Spring.Rest.Client.Support.DefaultResponseErrorHan dler.HandleError(Uri requestUri, HttpMethod requestMethod, IClientHttpResponse response)
at Spring.Rest.Client.RestTemplate.HandleResponseErro r(Uri uri, HttpMethod method, IClientHttpResponse response, IResponseErrorHandler errorHandler)
at Spring.Rest.Client.RestTemplate.ResponseReceivedCa llback[T](ClientHttpRequestCompletedEventArgs responseReceived)

Maybe I'm using wrong post method. Or maybe entity object is wrong.

If you need more information please let me know.

Thanks,
Slobodan.
