I'm just trying to run a background job with ABP.IO project and Hangfire (I have already made it with aspnetboilerplate without any issue)
Each time my recurringjob start it throw this error :
A suitable constructor for type 'AbpIo.TachePlan.ITachePlanifiee' could not be located.
For this test I just write an Interface in Contracts project
using System;
using System.Collections.Generic;
using System.Text;
namespace AbpIo.TachePlan
{
public interface ITachePlanifiee
{
void Test();
}
}
and the implementation in Application project
using System;
using System.Collections.Generic;
using System.Text;
namespace AbpIo.TachePlan
{
public class TachePlanifiee : ITachePlanifiee
{
public TachePlanifiee()
{ }
public void Test()
{
//Great job
}
}
}
In the web project
public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
//default ABP.IO code
app.UseHangfireDashboard();
RecurringJob.AddOrUpdate<ITachePlanifiee>(x=> x.Test(), "*/15 * * * *");
}
but result is
System.InvalidOperationException
A suitable constructor for type 'AbpIo.TachePlan.ITachePlanifiee' could not be located. Ensure the type is concrete and services are registered for all parameters of a public constructor.

I need help because I don't understant where is my mistake
Regards
Thank you for you comments, they help me.
So I found my mistake.
My interface didn't implement one of these interface
ITransientDependency
ISingletonDependency
IScopedDependency
https://docs.abp.io/en/abp/latest/Dependency-Injection
using Volo.Abp.DependencyInjection;
namespace AbpIo.TachePlan
{
public interface ITachePlanifiee : ITransientDependency
{
void Test();
}
}

I am trying to create a method decorator using Fody but it gives me the following error:
I have taken specific care to not wrap my IMethodDecorator inside any namespace as has been mentioned in a lot of places online. Following is the sample code I am trying in a console app.
IMethodDecorator
using System;
using System.Reflection;
public interface IMethodDecorator
{
void OnEntry(MethodBase method);
void OnExit(MethodBase method);
void OnException(MethodBase method, Exception exception);
}
MethodDecoratorAttribute
using System;
using System.Diagnostics;
using System.Reflection;
using FODYPOC;
// Atribute should be "registered" by adding as module or assembly custom attribute
[module: MethodDecorator]
namespace FODYPOC
{
// Any attribute which provides OnEntry/OnExit/OnException with proper args
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Constructor | AttributeTargets.Assembly | AttributeTargets.Module)]
public class MethodDecoratorAttribute : Attribute, IMethodDecorator
{
// instance, method and args can be captured here and stored in attribute instance fields
// for future usage in OnEntry/OnExit/OnException
public MethodDecoratorAttribute() { }
public void OnEntry(MethodBase method)
{
Console.WriteLine();
}
public void OnExit(MethodBase method)
{
Console.WriteLine();
}
public void OnException(MethodBase method, Exception exception)
{
Console.WriteLine();
}
}
public class Sample
{
[MethodDecorator]
public void Method()
{
Debug.WriteLine("Your Code");
}
}
}
Can someone point me in the right direction. It looks pretty simple to implement and I know I am making a very silly mistake somewhere.
Apparently the latest version of MethodDecorator.Fody (Version 0.9.0.6 currently) was not working. Downgrading the version to version 0.8.1.1 fixed the issue for me.
After a little more investigation, it appears that the interface method signatures were different in the two versions. So when I had the new package, it was not expecting MethodBase as a parameter and due to not finding anything that matches the interface it expects, it was throwing the error.
I have a problem with MVC4 StructureMap configuration, when I run the project the compiler fires this error
No Default Instance defined for PluginFamily Mace_CrmSystem.Controllers.HomeController
this is my code
global.aspx code
namespace Mace_CrmSystem
{
// Note: For instructions on enabling IIS6 or IIS7 classic mode,
// visit http://go.microsoft.com/?LinkId=9394801
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteTable.Routes.MapRoute("Oqla", "Oqla", new { controller = "Home", action = "index" });
RouteConfig.RegisterRoutes(RouteTable.Routes);
ControllerBuilder.Current.SetControllerFactory(new MyCustomeFactory());
ObjectFactory.Initialize(x => x.For<string>().Use<string>());
}
}
}
MycustomeFactory class
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using StructureMap;
namespace Mace_CrmSystem
{
public class MyCustomeFactory : System.Web.Mvc.DefaultControllerFactory
{
protected override System.Web.Mvc.IController GetControllerInstance(System.Web.Routing.RequestContext requestContext, Type controllerType)
{
return StructureMap.ObjectFactory.GetInstance(controllerType) as System.Web.Mvc.IController;
}
}
}
Controller class
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace Mace_CrmSystem.Controllers
{
public class HomeController : Controller
{
//
// GET: /Home/
public HomeController(string parameter)
{
TempData["Hi"] = "Hi";
}
public ActionResult Index()
{
return View();
}
}
public class logger
{
public void log()
{
}
}
}
what I noticed that when I add a parameter of type object like
public HomeController(logger parameter)
instead of
public HomeController(string parameter)
and
ObjectFactory.Initialize(x => x.For<logger>().Use<logger>());
instead of
ObjectFactory.Initialize(x => x.For<string>().Use<string>());
it works probably but with the string parameter it does not work .
so please couold anyone explain that for me.
From my understanding of StructureMap (and someone please correct me if I'm wrong) the reason you're seeing the behaviour that you're seeing is because StructureMap will use the longest constructor by default and attempt to fill in the parameters with the default instance registered with StructureMap.
In your instance you're not providing a default instance of string so StructureMap doesn't know how to resolve it.
If you wish to do what you're trying to do then your best bet is to look at creating a custom convention (see this answer for more information), however these do rely on knowing the name of the property your constructor is expecting.
Generally though, when dealing with strings your best bet is to move the string to an intermediate type and inject that instead.
I've been trying to get the Dispose method on my IDisposable WCF service called whilst using Ninject's NinjectServiceHost without any luck. I've then downloaded the Ninject.extensions.WCF example code and tried to get the IDisposable TimeService's Dispose() method to be called, but it does not get called either.
The service is instantiated correctly, just the Dispose() doesn't get called.
Is this a bug or something that myself and the example code are missing?
I've created a stripped down service and testing host that reproduces the issue. The code is below.
I'm using Ninject 3.0.1.10, Ninject.extensions.WCF 3.0.0.5, .net 4.5
ServiceModule.cs code (for setting up bindings)
using Ninject.Modules;
namespace TestNinjectWcf
{
public class ServiceModule : NinjectModule
{
public override void Load()
{
Bind<Service1>().ToSelf();
// I've also tried Bind<IService1>().To<Service1>()
// and also tried various scopes such as InParent() and InRequestScope()
}
}
}
Console Test Program to start the service.
using System;
using Ninject.Extensions.Wcf;
using Ninject;
using TestNinjectWcf;
namespace TestConsole
{
class Program
{
static void Main(string[] args)
{
var kernel = new StandardKernel(new ServiceModule());
var service = kernel.Get<NinjectServiceHost<Service1>>();
service.Open();
Console.WriteLine("Service Started");
Console.ReadKey();
service.Close();
}
}
}
Service Implementation
using System;
using System.Diagnostics;
using System.ServiceModel;
namespace TestNinjectWcf
{
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple)]
public class Service1 : IService1, IDisposable
{
public Service1()
{
Debug.WriteLine("Constructor");
}
public string GetData(int value)
{
return string.Format("You entered: {0}", value);
}
public void Dispose()
{
Debug.WriteLine("Dispose"); // This line never gets called!
}
}
}
Maybe it is that you have created singleton service ? (InstanceContextMode.Single)
Only one InstanceContext object is used for all incoming calls and is not recycled subsequent to the calls. If a service object does not exist, one is created
First question is, how can I get the type of an object stored in a variable? Generally we do:
Type t = typeof(ClassName); //if I know the class
but, how can I say something:
Type t = typeof(varClassName); //if the class name is stored in a variable
Second question, a broader picture is, I have a WCF service that contains a DataContract class say "MyClass" and I have defined a custom attribute called "MyAttribute" to it. There is one method say "GetDataUsingDataContract" with a parameter of type MyClass. Now on client, I invoke the webservice. I use MethodInfo and ParameterInfo classes to get the parameters of the method in question. But how can I access the attributes of the method parameter which is actually a class Myclass? Here is the code that I tried:
MyService.Service1Client client = new MyService.Service1Client();
Type t = typeof(MyService.Service1Client);
MethodInfo members = t.GetMethod("GetDataUsingDataContract");
ParameterInfo[] parameters = members.GetParameters();
foreach (var parameter in parameters)
{
MemberInfo mi = parameter.ParameterType; //Not sure if this the way
object[] attributes;
attributes = mi.GetCustomAttributes(true);
}
Above code doesn't retrieve me the custom attribute "MyAttribute". I tried the concept in the class that is defined in the same project and it works. Please HELP!
but, how can I say something:
Type t = typeof(varClassName); //if the class name is stored in a variable
Try
Type.GetType("varClassName", false, true);
As to your second question:
Above code doesn't retrieve me the
custom attribute "MyAttribute". I
tried the concept in the class that is
defined in the same project and it
works. Please HELP!
Just guessing, I'm not sure that attributes are exposed to the client, by default. I think its the same issue as an untrusted assembly. Some attributes are sensitive info. See this:
http://blogs.msdn.com/b/haibo_luo/archive/2006/02/21/536470.aspx
But you could try linking the service project types into your app by first referencing the service assembly in your client project, then going to your service reference -> "Configure Service Reference" and selecting "Reuse types in all referenced assemblies". I'm not sure this option will affect the service interface classes, but I use it often with my domain objects. Worth a try.
Type mi = parameter.ParameterType; //Not sure if this the way
object[] attributes;
attributes = mi.GetCustomAttributes(true);
Ensure your proxy class has knowledge on attributes
