I have a WCF service and I am trying to install it using installutil, so when performing the installation below errors are raised:
The service MyService has been installed correctly.
Creating the EventLog source MyService in the Application Registry...
Exception during the installation phase.
System.ArgumentException: The source code MyService already exists in the local machine.
Then it rollback and uninstall it.
I have below classes to install service and EventLog:
[RunInstaller(true)]
public class MyEventLogInstaller : Installer
{
private EventLogInstaller myEventLogInstaller;
public MyEventLogInstaller()
{
//Create Instance of EventLogInstaller
this.myEventLogInstaller = new EventLogInstaller();
// Set the Source of Event Log, to be created.
this.myEventLogInstaller.Source = "TEST";
// Set the Log that source is created in
this.myEventLogInstaller.Log = "Application";
// Add myEventLogInstaller to the Installers Collection.
Installers.Add(this.myEventLogInstaller);
}
}
[RunInstaller(true)]
public class ProjectInstaller : Installer
{
private ServiceProcessInstaller process;
private ServiceInstaller service;
public ProjectInstaller()
{
this.process = new ServiceProcessInstaller();
this.process.Account = ServiceAccount.LocalSystem;
this.service = new ServiceInstaller();
this.service.ServiceName = "MyService";
Installers.Add(process);
Installers.Add(service);
}
}
They are both in the same namespace.
Also in the constructor of the WCF Service I have the following lines:
if (!System.Diagnostics.EventLog.SourceExists("TEST"))
{
System.Diagnostics.EventLog.CreateEventSource("TEST", "Application");
}
this.eventLog = new System.Diagnostics.EventLog();
this.eventLog.Source = "TEST";
this.eventLog.Log = "Application";
Any ideas?

Whenever I try to restart Avalonia application form base application, I get an exception: "Setup was already called on one of AppBuilder instances." on SetupWithLifetime() call.
Application Startup code is:
public static void Start()
{
lifeTime = new ClassicDesktopStyleApplicationLifetime()
{
ShutdownMode = ShutdownMode.OnLastWindowClose
};
BuildAvaloniaApp().SetupWithLifetime(lifeTime);
lifeTime.Start(new[] { "" });
}
public static AppBuilder BuildAvaloniaApp()
=> AppBuilder.Configure<App>()
.UsePlatformDetect()
.LogToTrace()
.UseReactiveUI();
Application shutdown code is:
lifeTime.Shutdown();
lifeTime.Dispose();
Here's a link to functional example code, which produces this error: https://pastebin.com/J1jqppPv
Has anyone encountered such problem? Thank you
SetupWithLifetime calls Setup which can only be called once. A possible solution is to call SetupWithoutStarting on BuildAvaloniaApp, which can only be called once as well, for example:
private static AppBuilder s_builder;
static void Main(string[] args)
{
s_builder = BuildAvaloniaApp();
}
public static void Start()
{
lifeTime = new ClassicDesktopStyleApplicationLifetime()
{
ShutdownMode = ShutdownMode.OnLastWindowClose
};
s_builder.Instance.Lifetime = lifeTime;
s_builder.Instance.OnFrameworkInitializationCompleted();
lifeTime.Start(new[] { "" });
}
private static AppBuilder BuildAvaloniaApp()
=> AppBuilder.Configure<App>()
.UsePlatformDetect()
.LogToTrace()
.UseReactiveUI();
Additional note: Restarting the app probably won't work on macOS.
I am wondering what the best approach to toggling App.Config settings for C# would be. This is involving our test suite, and we would like the option to either choose a remote or local environment to kick the tests off. We use LeanFT and NUnit as our testing framework, and currently in order to get tests to run remote we have to add an <leanft></leanft> config in the App.config file. How can I specify different configurations at run time when I kick these tests off thru the command line? Thanks!
Any leanft configuration can be modified at runtime, by using the SDK namespace or the Report namespace.
Here's an example using NUnit 3 showing how you can achieve this
using NUnit.Framework;
using HP.LFT.SDK;
using HP.LFT.Report;
using System;
namespace LeanFtTestProject
{
[TestFixture]
public class LeanFtTest
{
[OneTimeSetUp]
public void TestFixtureSetUp()
{
// Initialize the SDK
SDK.Init(new SdkConfiguration()
{
AutoLaunch = true,
ConnectTimeoutSeconds = 20,
Mode = SDKMode.Replay,
ResponseTimeoutSeconds = 20,
ServerAddress = new Uri("ws://127.0.0.1:5095") // local or remote, decide at runtime
});
// Initialize the Reporter (if you want to use it, ofc)
Reporter.Init(new ReportConfiguration()
{
Title = "The Report title",
Description = "The report description",
ReportFolder = "RunResults",
IsOverrideExisting = true,
TargetDirectory = "", // which means the current parent directory
ReportLevel = ReportLevel.All,
SnapshotsLevel = CaptureLevel.All
});
}
[SetUp]
public void SetUp()
{
// Before each test
}
[Test]
public void Test()
{
Reporter.ReportEvent("Doing something", "Description");
}
[TearDown]
public void TearDown()
{
// Clean up after each test
}
[OneTimeTearDown]
public void TestFixtureTearDown()
{
// If you used the reporter, invoke this at the end of the tests
Reporter.GenerateReport();
// And perform this cleanup as the last leanft step
SDK.Cleanup();
}
}
}
I am using #RabbitListner annotation to recieve messages from a RabbitMq queue.
Although I have done all steps required to do this (i.e. Add #EnableRabbit annotation in my config class) and declare SimpleRabbitListenerContainerFactory as a bean , still my method is not recieving messages from the queue . Can anybody suggest what I am missing :
I am using Spring Boot to launch my application
My launch class
#Configuration
#EnableAutoConfiguration
#EnableRabbit
#EnableConfigurationProperties
#EntityScan("persistence.mysql.domain")
#EnableJpaRepositories("persistence.mysql.dao")
#ComponentScan(excludeFilters = { #ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = ApiAuthenticationFilter.class),#ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = ApiVersionValidationFilter.class)},basePackages = {"common", "mqclient","apache", "dispatcher" })
public class Application {
public static void main(final String[] args) {
final SpringApplicationBuilder appBuilder = new SpringApplicationBuilder(
Application.class);
appBuilder.application().setWebEnvironment(false);
appBuilder.profiles("common", "common_mysql_db", "common_rabbitmq")
.run(args);
}
#Bean
#Primary
#ConfigurationProperties(prefix = "spring.datasource")
public DataSource primaryDataSource() {
return DataSourceBuilder.create().build();
}
}
Here is my Bean to define SimpleRabbitListenerContainerFactory inside a component class
#Component(value = "inputQueueManager")
public class InputQueueManagerImpl extends AbstractQueueManagerImpl {
..///..
#Bean(name = "inputListenerContainerFactory")
public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory()
{
SimpleRabbitListenerContainerFactory factory = new
SimpleRabbitListenerContainerFactory();
factory.setConnectionFactory(this.rabbitConnectionFactory);
factory.setConcurrentConsumers(Integer.parseInt(this.concurrentConsumers));
factory.setMaxConcurrentConsumers(Integer.parseInt(this.maxConcurrentConsumers));
factory.setMessageConverter(new Jackson2JsonMessageConverter());
return factory;
}
}
And finally my Listener inside another Controller component
#Controller
public class RabbitListner{
#RabbitListener(queues = "Storm1", containerFactory = "inputListenerContainerFactory")
#Override
public void processMessage(QueueMessage message) {
String topic = message.getTopic();
String payload = message.getPayload();
dispatcher.bean.EventBean eventBean = new dispatcher.bean.EventBean();
System.out.println("Data read from the queue");
Unfortunately , I am sending the messages to the queue but the code inside processMessage is not getting executed ever.
I am not sure what is the problem here . Can anybody help ??
By default, the Json message converter requires hints in the message properties as to what type of object to create.
If your producer does not set those properties, it won't be able to do the conversion without some help.
You can inject a ClassMapper into the converter.
The framework provides a DefaultClassMapper which can be customized - either to look at a different message property than the default __TypeId__ property.
If you always want to convert the json to the same object, you can simply set the default type:
DefaultClassMapper classMapper = newDefaultClassMapper();
classMapper.setDefaultType(QueueMessage.class);
Jackson2JsonMessageConverter converter = new Jackson2JsonMessageConverter();
converter.setClassMapper(classMapper);
factory.setMessageConverter(new Jackson2JsonMessageConverter());
The documentation already shows how to configure this.
I have these three packages loaded to my WCF service project:
EnterpriseLibrary.Common Version 6.0.1304.0
EnterpriseLibrary.ExceptionHandling 6.0.1304.0
EnterpriseLibrary.ExceptionHandling.WCF Version 6.0.1304.0
Here is the service interface and MyTestFault DataContract:
[ServiceContract]
public interface IRepairService
{
[OperationContract]
[FaultContract(typeof(MyTestFault))]
string SaveRepairCode(string failureCode, string description);
}
[DataContract]
public class MyTestFault
{
#region Member Fields
private string _message = "An unexpected error occured while executing the service method.";
#endregion
#region Properties
[DataMember]
public string Message
{
get { return _message; }
set { _message = value; }
}
#endregion
#region Constructor(s)
public MyTestFault() { }
#endregion
}
Here is the implementation of the service:
[ExceptionShielding("TestPolicy")]
public class RepairService : IRepairService
{
#region Private members
private WimDAL wimDAL;
ExceptionManager exManager;
#endregion
#region Constructor(s)
public RepairService()
{
wimDAL = new WimDAL();
var testPolicy = new List<ExceptionPolicyEntry>
{
{
new ExceptionPolicyEntry(
typeof(SqlException),
PostHandlingAction.ThrowNewException,
new IExceptionHandler[]
{
new FaultContractExceptionHandler(
typeof(MyTestFault),
"SqlException Occurred.",
new NameValueCollection(){ { "Message", "Message" }})
})
},
{
new ExceptionPolicyEntry(
typeof(Exception),
PostHandlingAction.ThrowNewException,
new IExceptionHandler[]
{
new FaultContractExceptionHandler(
typeof(MyTestFault),
"Exception Occurred.",
new NameValueCollection(){ { "Message", "Message" }})
})
}
};
var policies = new List<ExceptionPolicyDefinition>();
policies.Add(new ExceptionPolicyDefinition(
"TestPolicy", testPolicy));
exManager = new ExceptionManager(policies);
}
#endregion
/// <summary>
/// Insert a new fail code with description into RPCODE.
/// Duplicate primary key will throw SqlException that should be processed by EHAB
/// </summary>
public string SaveRepairCode(string failureCode, string description)
{
using (TransactionScope txScope = new TransactionScope())
{
WimSQLCommand sc = new WimSQLCommand() { StoredProcedure = "Repair.RPCODE_Insert" };
sc.Parameters.Add(new SqlParameter("#FailureCode", failureCode));
sc.Parameters.Add(new SqlParameter("#Desc", description));
exManager.Process(() => wimDAL.Execute_NonQueryNoReturn(sc), "TestPolicy");
txScope.Complete();
return "<Save_Repair_Code></Save_Repair_Code>";
}
}
}
Now, I have a TestClient console application that is part of the same project that has a reference to the project and a service reference. From there I call the SaveRepairCode() method and try to catch the specific fault exception like so:
ServiceReference1.RepairServiceClient r = new ServiceReference1.RepairServiceClient();
Console.WriteLine("Enter a new repair code:");
string repairCode = Console.ReadLine();
Console.WriteLine("Enter description:");
string description = Console.ReadLine();
try
{
r.SaveRepairCode(repairCode, description);
}
catch (FaultException<MyTestFault> ex)
{
//do something
throw;
}
catch (FaultException fex)
{
//do something
throw;
}
Finally, I run the console app and try to save a duplicate repair code. I know through debugging that this causes the SqlException to occur. After I step over the SqlException, I see the "FaultContractWrapperException was unhandled by user code" exception and it has the message I specified in the policy of "SqlException occurred.". When I step over that I get back to the client and see this error:
CommunicationException was unhandled
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
PS - this is Enterprise Library 6 with WCF and I made no manual changes to the web.config... and yes, includeExceptionDetailInFaults is set to false.
What am I missing here? Thanks in advance.
UPDATE
Looks like I was missing this one line of code after instantiating the new ExceptionManager.
ExceptionPolicy.SetExceptionManager(exManager);
Nice to see that this one line of code is NOT in the Enterprise Library 6 - April 2013.chm but it IS in the "Developer's Guide to Microsoft Enterprise Library-Preview.pdf" on page 90 of 269. After including that one line I get into the proper FaultException catch on the client.
With that being said, I still can't get other MyTestFault properties on the client. For example, if I add public string StoredProcedureName to MyTestFault and map it to the SqlException's "Procedure" property, I always see null on the client. The only change in the policy for this would be to add the mapping like so:
new NameValueCollection(){ { "Message", "{Message}" }, { "StoredProcedureName", "{Procedure}" } }
It turns out this line was the culprit.
exManager.Process(() => wimDAL.Execute_NonQueryNoReturn(sc), "TestPolicy");
Insead of using the ExceptionManager's Process method, just execute the command you expect a potential exception for like so.
wimDAL.Execute_NonQueryNoReturn(sc);
This does not follow what the "Developer's Guide to Microsoft Enterprise Library-Preview.pdf" says but I guess the documentation is still a work in progress. I hope this helps someone else.
I'm trying to run a self hosted executable as a Windows service. I'm using the MVC 4 beta Web API. First I used Derik Whittaker's blog for setting up the basic console application and tested it with positive results.
I then used Einar Egilsson's blog to make it work as both a console application and a windows service. The application installed as a service just fine. I set the service logon to use my own for this basic testing; it failed to bind to the socket without this. When the service starts up I see all my trace logs as expected there are no fatal errors. The application appears to be running normally. When I test using fiddler using the same request for the console application I get a "HTTP/1.1 500 Internal Server Error".
Using this same code when I turn off the service then launch using F5 in VS the application starts up just fine and serves the same request!? The log entries are identical within the same execution paths.
public partial class TestService : ServiceBase {
private static readonly Logger Logger = LogManager.GetCurrentClassLogger();
private HttpSelfHostServer _server;
static void Main(string[] args) {
Logger.Debug("Main Called");
var service = new TestService();
if (Environment.UserInteractive) {
Logger.Debug("Environment.UserInteractive == true");
Console.WriteLine("Press any key to stop program");
service.OnStart(args);
service.OnStop();
} else {
Logger.Debug("Environment.UserInteractive == false");
try {
Run(service);
} catch(Exception exception) {
Logger.Fatal(exception.Message, exception);
}
}
}
protected override void OnStart(string[] args) {
Logger.Debug("OnStart called");
var hostUri = string.Format("http://{0}:{1}", Environment.MachineName, ConfigurationManager.AppSettings["Service.Port"]);
Logger.Debug("URL:" + hostUri);
var selfHostConfiguration = new HttpSelfHostConfiguration(hostUri);
selfHostConfiguration.Routes.MapHttpRoute(
name: "DefaultApiRoute",
routeTemplate: "endpoints/{controller}",
defaults: null
);
Logger.Debug("Routes registered");
try {
using (_server = new HttpSelfHostServer(selfHostConfiguration)) {
Logger.Debug("Hosting at " + hostUri + "/endpoints/{controller}");
_server.OpenAsync().Wait();
if (Environment.UserInteractive) { // *** I've tried this commented out as well
Console.ReadLine();
}
Logger.Debug("End of using");
}
} catch(Exception exception) {
Logger.Fatal(exception.Message, exception);
if(exception.InnerException != null) {
Logger.Fatal(exception.InnerException.Message, exception.InnerException);
}
}
}
protected override void OnStop() {
_server.Dispose();
}
}
It has been some time since you posted this but I wanted to input.
I don't know why this is, but the internal error comes from initializing the self host inside the onStart method. You must initialize it in the constructor of the service and then only call the _server.OpenAsync() in the onStart method.
Or at least that is what worked for me.
Use TopShelf. I just blogged about how to do that.
as i can see, you use _server.OpenAsync().Wait(); in OnStart method. This just makes your initialization code to freeze, all code after that line will not execute. To avoid this try to remove .Wait() from the OpenAsync().
