Question

在工作中我们需要一个小应用程序，并决定测试一些我们并不熟悉这个项目的东西。

我开始使用控制台应用程序，使用topshelf通过nancy selfhosting包托管nancy。所有这一切都有效。

现在我想将DryIoc容器连接到nancy bootstrapper中，并出现以下错误：

System.MissingMethodException
  HResult=0x80131513
  Message=Method not found: 'DryIoc.Rules DryIoc.Rules.With(DryIoc.FactoryMethodSelector, DryIoc.ParameterSelector, DryIoc.PropertiesAndFieldsSelector, Boolean)'.
  Source=Nancy.Bootstrappers.DryIoc

   at Topshelf.Hosts.ConsoleRunHost.Run()

我的引导程序：空，没有注册，因为我首先要测试它在使它变得更复杂之前

public class Bootstrapper : DryIocNancyBootstrapper
{
    protected override void ApplicationStartup(IContainer container, IPipelines pipelines)
    {
        //No registrations should be performed in here, however you may
        //resolve things that are needed during application startup.
        base.ApplicationStartup(container, pipelines);
    }

    protected override void ConfigureApplicationContainer(IContainer container)
    {
        //Perform registation that should have an application lifetime
        base.ConfigureApplicationContainer(container);
    }

    protected override void ConfigureRequestContainer(IContainer container, NancyContext context)
    {
        //Perform registrations that should have a request lifetime
        base.ConfigureRequestContainer(container, context);
    }

    protected override void RequestStartup(IContainer container, IPipelines pipelines, NancyContext context)
    {
        // No registrations should be performed in here, however you may
        // resolve things that are needed during request startup.
        base.RequestStartup(container, pipelines, context);
    }
}

在我的.Start方法中通过topshelf获取分配引导程序的服务

public void Start()
{
    var hostConfig = new HostConfiguration() { UrlReservations = new 
    UrlReservations { CreateAutomatically = true } };
    var uri = new Uri(_hostUrl);
    _nancyHost = new NancyHost(uri, new Bootstrapper(), hostConfig);
    _nancyHost.Start();
}

新NancyHost发生错误（uri，new Bootstrapper（），hostConfig）;一旦我将新的Bootstrapper（）添加到参数

中

听起来像版本问题。检查.config文件以获取dryioc的绑定重定向。

似乎DryIocNancyBootstrapper认为它使用的是DryIOC的X版本，而是使用版本Y（由于绑定重定向），但没有使用该方法（要么它被删除，要么它是一个尚未拥有它的旧版本。

找出DryIocNancyBootstrapper想要的版本（即上例中的版本X）并引用该版本。

nancy selfhost，with dryioc和bootstrapper - ＆gt;方法未找到异常
