Добрый день?
Пишу тест приложение, получающее данные из MS CRM 3.0
например вот так:

CrmService service = new CrmService();
service.Credentials = System.Net.CredentialCache.DefaultCredentials;
service.Url = "http://crm:5555/mscrmservices/2006/crmservice.asmx";
opportunity crmOpportunity = new opportunity();
Guid custAccountGuid = new Guid("F4D00C90-89C9-DA11-86AF-000BDB5C46AB");
crmOpportunity.customerid = new Customer();
crmOpportunity.customerid.Value = custAccountGuid;
crmOpportunity.customerid.type = EntityName.account.ToString();
crmOpportunity.opportunityratingcode = new Picklist();
crmOpportunity.opportunityratingcode.Value = 2;
crmOpportunityId = service.Create(crmOpportunity);
Guid crmOpportunityId;

то пример работает, а если выполнить запрос, например вот так

string fetch1 = "<fetch mapping='logical'>";
fetch1 += "<entity name='account'><all-attributes/>";
fetch1 += "</entity></fetch>";
String result1 = service.Fetch(fetch1);

то падает с ошибкой
"The underlying connection was closed: The connection was closed unexpectedly."
