使用Ninject Dispose的WCF未在requestscope中触发 [英] WCF using Ninject Dispose not triggering in requestscope

问题描述

这是我的模块

internal class WebServiceConfiguration : NinjectModule
{
    public override void Load()
    {
        Bind<IWebService>().To<WebService>().InRequestScope();
    }
}

这是global.asax

Here is the global.asax

public class Global : NinjectHttpApplication
{
    protected override IKernel CreateKernel()
    {
        return new StandardKernel(new WebServiceConfiguration());
    }
}

我还尝试了InScope(c => OperationContext.Current)

I also tried InScope(c => OperationContext.Current)

这是我在IWebService中具有IDisposable的服务

Here is my service with IDisposable in IWebService

[ServiceBehavior(InstanceContextMode = InstanceContextModeDefinition.Mode)]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class WebService : IWebService
{
    private readonly ISomeService _someService;

    public WebService(ISomeService someService)
    {
        _someService = someService;
    }

    public void Dispose()
    {
        _someService.Dispose();
    }

这是服务标记中的ServiceHostFactory

Here is the ServiceHostFactory in the service markup

<%@ ServiceHost Language="C#" Debug="true" Factory="Ninject.Extensions.Wcf.NinjectDataServiceHostFactory" Service="WCFTest.Services.WebService" CodeBehind="WebService.svc.cs" %>

注入依赖项是可行的.我唯一担心的是，当客户端关闭服务调用时，不会触发dispose方法.

The injection of dependencies works. My only concern is that the dispose method is not being triggered when the Client closes the service call.

我试图删除Factory ="Ninject.Extensions.Wcf.NinjectDataServiceHostFactory"只是为了测试是否将调用Dipose，并且确实调用了Dipose，但是我当然不会进行自动注入.因此，可能是我在设置中做错了什么?还是ninject没有调用Dispose的错误?

I tried to remove the Factory="Ninject.Extensions.Wcf.NinjectDataServiceHostFactory" just to test if the Dipose will be called, and it did call but of course i won't have auto injection. So there might be something i'm doing wrong in the setup? or there is a bug on ninject not calling Dispose?

注意:我在ninject wcf扩展中获取了示例设置，只是添加了一些DI.

Note: I grab the sample setup in ninject wcf extension and just added some DI.

您的帮助将不胜感激.

顺便说一句:我正在使用Ninject 3.0.0.15，Ninject.Extensions.Wcf 3.0.0.5，Ninject.Web.Common 3.0.0.7

BTW: I'm using Ninject 3.0.0.15, Ninject.Extensions.Wcf 3.0.0.5, Ninject.Web.Common 3.0.0.7

推荐答案

使用

Bind<IWebService, WebService>().To<WebService>().InRequestScope();
