Close Incident in CRM 2011 with Silverlight - silverlight

Question

I have an big issue to close an incident with the Dynamics CRM 2011 Organization Service. There is no CloseIncidentRequest class avaiable and also with fetch xml I've no chance:
public void CloseCase(Guid pCaseId)
{
FetchExpression fetch = new FetchExpression();
String requestMain = "";
requestMain += "<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">";
requestMain += " <s:Body>";
requestMain += " <Execute xmlns=\"http://schemas.microsoft.com/xrm/2011/Contracts/Services\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">";
requestMain += " <request i:type=\"b:CloseIncidentRequest\" xmlns:a=\"http://schemas.microsoft.com/xrm/2011/Contracts\" xmlns:b=\"http://schemas.microsoft.com/crm/2011/Contracts\">";
requestMain += " <a:Parameters xmlns:c=\"http://schemas.datacontract.org/2004/07/System.Collections.Generic\">";
requestMain += " <a:KeyValuePairOfstringanyType>";
requestMain += " <c:key>IncidentResolution</c:key>";
requestMain += " <c:value i:type=\"a:Entity\">";
requestMain += " <a:Attributes>";
requestMain += " <a:KeyValuePairOfstringanyType>";
requestMain += " <c:key>incidentid</c:key>";
requestMain += " <c:value i:type=\"a:EntityReference\">";
requestMain += " <a:Id>{0}</a:Id>";
requestMain += " <a:LogicalName>incident</a:LogicalName>";
requestMain += " <a:Name i:nil=\"true\" />";
requestMain += " </c:value>";
requestMain += " </a:KeyValuePairOfstringanyType>";
requestMain += " <a:KeyValuePairOfstringanyType>";
requestMain += " <c:key>subject</c:key>";
requestMain += " <c:value i:type=\"d:string\" xmlns:d=\"http://www.w3.org/2001/XMLSchema\">Parent Case has been resolved</c:value>";
requestMain += " </a:KeyValuePairOfstringanyType>";
requestMain += " </a:Attributes>";
requestMain += " <a:EntityState i:nil=\"true\" />";
requestMain += " <a:FormattedValues />";
requestMain += " <a:Id>{1}</a:Id>";
requestMain += " <a:LogicalName>incidentresolution</a:LogicalName>";
requestMain += " <a:RelatedEntities />";
requestMain += " </c:value>";
requestMain += " </a:KeyValuePairOfstringanyType>";
requestMain += " <a:KeyValuePairOfstringanyType>";
requestMain += " <c:key>Status</c:key>";
requestMain += " <c:value i:type=\"a:OptionSetValue\">";
requestMain += " <a:Value>5</a:Value>";
requestMain += " </c:value>";
requestMain += " </a:KeyValuePairOfstringanyType>";
requestMain += " </a:Parameters>";
requestMain += " <a:RequestId i:nil=\"true\" />";
requestMain += " <a:RequestName>CloseIncident</a:RequestName>";
requestMain += " </request>";
requestMain += " </Execute>";
requestMain += " </s:Body>";
requestMain += "</s:Envelope>";
fetch.Query = String.Format(requestMain, pCaseId.ToString(), pCaseId.ToString());
_orgService.BeginRetrieveMultiple(fetch, CloseCaseResult, null);
Any idea to solve this problem?
Best Regards

Recheck following article about calling of IOrganizationService in silverlight - http://mileyja.blogspot.com/2011/06/retrieve-entity-in-microsoft-dynamics.html
First part of code (creation of request) should be replaced with following code:
Entity incidentresolution = new Entity()
{
LogicalName = "incidentresolution"
};
incidentresolution["subject"] = "Incident was closed";
incidentresolution["incidentid"] = new EntityReference()
{
Id = Guid.Empty,
LogicalName = "incident"
};
OrganizationRequest request = new OrganizationRequest()
{
RequestName = "CloseIncident"
};
request["incidentresolution"] = incidentresolution;
request["status"] = new OptionSetValue()
{
Value = -1
};
Of course you should replace Guid.Empty with id of incident you want to close.
