How to diagnose Error.WaitForScopedServiceIsCreatedTimeoutExpired?

@yallie First, hi again.

Unable to get the service registration for the problematic FactoryID=20713656

Given the FactoryID is greater than 16 bit, it means that it is actually a decorator with upper 16 bits corresponding to the Decorated FactoryID. And it's need to be fixed to account for this situation.

You may try to use this code until it's fixed:

        public static string TryGetDetails(IContainer container, ContainerException ex)
        {
            var e = ex.Error;
            if (e == DryIoc.Error.WaitForScopedServiceIsCreatedTimeoutExpired)
            {
                var factoryId = (int)ex.Details;

                // check `Request.CombineDecoratorWithDecoratedFactoryID()` for why is this logic
                // var decoratorFactoryId = 0; // todo: @wip #598 add search for the `decoratorFactoryId`
                if (factoryId > ushort.MaxValue)
                {
                    // decoratorFactoryId = factoryId & ushort.MaxValue;
                    factoryId = factoryId >> 16;
                }

                foreach (var reg in container.GetServiceRegistrations()) 
                {
                    var f = reg.Factory;
                    if (f.FactoryID == factoryId)
                        return $"The service registration related to the problem is:{Environment.NewLine}{reg}";
                    var genFactories = f.GeneratedFactories;
                    if (genFactories != null)
                        foreach (var genEntry in f.GeneratedFactories.Enumerate()) 
                        {
                            var generatedFactory = genEntry.Value;
                            if (generatedFactory.FactoryID == factoryId)
                                return $"The service registration related to the problem is:{Environment.NewLine}{reg}{Environment.NewLine}Specifically, its closed-generic factory is:{Environment.NewLine}{generatedFactory}";
                        }
                }
                return "Unable to find the service registration for the problematic factory with FactoryID={factoryId}";
            }
            return string.Empty;
        }

Also, the message doesn't have the number of ticks it waited: for the ticks.

It was fixed in #475

Hi Maksim, thanks a lot for the explanation and the code sample! 🚀
