I have a WCF service which worked fine til today, an exception System.ServiceModel.FaultException was thrown, when i call a method of the this service.
using (EService = new FaService.EServiceClient())
{
DataSet ds = EService.GetCompanies(3375); // exception here
DataTable dt = ds.Tables[0];
foreach (DataRow dr in dt.Rows)
{
Companies.Add(new Company() { Name = dr["c0"].ToString() });
}
}
