Question

我注册了我的实例ConfigureApplicationContainer：

public class Bootstrapper : DefaultNancyBootstrapper
{
    // The bootstrapper enables you to reconfigure the composition of the framework,
    // by overriding the various methods and properties.
    // For more information https://github.com/NancyFx/Nancy/wiki/Bootstrapper
    IParameterGetSetEngine _parameterGetSetEngine;

    public Bootstrapper(IParameterGetSetEngine parameterGetSetEngine)
    {
        _parameterGetSetEngine = parameterGetSetEngine;
    }

    protected override void ConfigureApplicationContainer(TinyIoCContainer container)
    {
        container.Register<IParameterGetSetEngine>(_parameterGetSetEngine);
        base.ConfigureApplicationContainer(container);
    }

}


public class ParametersModule : NancyModule
{
    IParameterGetSetEngine _parameterGetSetEngine;
    public ParametersModule(IParameterGetSetEngine parameterGetSetEngine)
    {
        _parameterGetSetEngine = parameterGetSetEngine;

        Get["/"] = parameters =>
        {
            return "Test";
        };
    }

}

当Nancy尝试创建ParametersModule时发生崩溃。看起来它试图创建ParameterGetSetEngine的实例。为什么它不使用我注册的实例？

好的从这里得到答案： Registering dependencies within TinyIOC for use in NancyFX

任何注册都应在以下情况发生：

base.ConfigureApplicationContainer(container);

Nancy TinyIoc不使用已注册的实例
