DryIoc: Enabling 'throwIfUnresolved' always throw an exception

Question

I want to know name of dependencies that are missed (not injected)!

I Use this extensions:

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

and I tried to use throwIfUnresolved parameter to solve the problem

Like this:

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

        //...
    }

but after that I always get this exception even if there is no dependency!

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'

Answer 1

Use this:

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

        //...
    }
