DryIoc：启用 'throwIfUnresolved' 总是抛出异常

Question

我想知道遗漏（未注入）的依赖项的名称！

我使用这个扩展：

• DryIoc.dll v4.0.7
• DryIoc.WebApi.dll v4.0.0
• DryIoc.Web.dll v4.0.0

我尝试使用throwIfUnresolved参数来解决问题

像这样：

    public static void Register(HttpConfiguration config)
    {
        var container = new Container().WithWebApi(config, throwIfUnresolved: type => true);

        //...
    }

但在那之后我总是得到这个异常，即使没有依赖！

DryIoc.ContainerException: 'Unable to resolve ModelMetadataProvider IsResolutionCall from Container with ambient ScopeContext DryIoc.AsyncExecutionFlowScopeContext without Scope Where no service registrations found and no dynamic registrations found in 0 of Rules.DynamicServiceProviders and nothing found in 0 of Rules.UnknownServiceResolvers'

使用这个：

    public static void Register(HttpConfiguration config)
    {
        var container = new Container()
            .WithWebApi(
                config,
                throwIfUnresolved: type => type.IsController());

        //...
    }
