Calling irServer SOAP Endpoint using a Service Reference

Prerequisites: A valid Service Reference
The following sample represents how to call irServer Rule Execution Service using a service reference:
using (RuleEngineServiceClient proxy = new RuleEngineServiceClient()) 
{ 
 try 
 { 
 // Get RuleApp as defined in the config (RepositoryRuleApp or FileSystemRuleApp) 
 RepositoryRuleApp rules = new RepositoryRuleApp(); 
 rules.RepositoryServiceUri = "http://server/InRuleCatalogService/Service.svc"; 
 RepositoryRuleAppRevisionSpec spec = new RepositoryRuleAppRevisionSpec(); 
 spec.RuleApplicationName = "MortgageCalculator"; 
 rules.RepositoryRuleAppRevisionSpec = spec; 
 rules.UserName = "Admin"; 
 rules.Password = "password"; 
 // Create new ApplyRulesRequest 
 ApplyRulesRequest request = new ApplyRulesRequest(); 
 request.RuleApp = rules; 
 request.EntityName = "Mortgage"; 
 request.RuleEngineServiceOutputTypes = new RuleEngineServiceOutputTypes(); 
 request.RuleEngineServiceOutputTypes.ActiveNotifications = true; 
 request.RuleEngineServiceOutputTypes.ActiveValidations = true; 
 request.RuleEngineServiceOutputTypes.EntityState = true; 
 // Load state XML 
 Console.WriteLine("- Loading XML state for 'Invoice'..."); 
 request.EntityState = `"<Mortgage><LoanInfo><Principal>500000</Principal><APR>6.875</APR>< TermInYears > 30 </TermInYears ></LoanInfo ><PaymentSummary/ ></Mortgage > "`; 
 Console.WriteLine("Input State:"); 
 Console.WriteLine(request.EntityState); 
 Console.WriteLine(""); 
 // Submit Request 
 Console.WriteLine("- Calling ApplyRules() from RuleEngineService..."); 
 RuleEngineServiceResponse response = proxy.ExecuteRuleEngineRequest(request); Console.WriteLine("Active Notifications:"); 
 foreach (Notification notification in response.ActiveNotifications) { 
 Console.WriteLine(notification.NotificationType + ": " + notification.Message); } 
 Console.WriteLine(""); 
 Console.WriteLine("Active Validations:"); 
 foreach (Validation validation in response.ActiveValidations) { 
 Console.WriteLine(validation.InvalidMessageText); 
 } 
 Console.WriteLine(""); 
 Console.WriteLine("Output State:"); 
 // Note: XML formatting not maintained in response 
 Console.WriteLine(response.EntityState); 
 Console.WriteLine(""); 
 } 
 catch (Exception ex) { 
 Console.WriteLine("Unknown exception occurred during RuleEngineService request: " + 
ex.ToString()); } 
} 
Console.WriteLine("[END ServiceReferenceConsumer Sample]");
