Following from another question I had, I can see Umbraco8 provides the lightinject DI setup. I could possibly switch to use this for basic DI.

What I was particularly struggling with is that I am factory class (pattern) which worked great with AutoFac and the named and keyed services. Autofac adds this to a IIndex.

In the DI I had this ...

            builder
            .RegisterAssemblyTypes(assembly)
            .Where(type => type.GetInterfaces().Contains(typeof(ITransform)))
            .Keyed<ITransform>(transform => transform.Name);

then in the factory class constructor I had ...

public TransformFactory(IMyAwesomeContext awesomeContext, IIndex

I had a number of classes implementing ITransform. Within the factory I could then simply do this ... to get at the required object.

            switch (nodeTypeAlias.ToLowerInvariant())
            {
                case "user":
                    _transforms.TryGetValue("UserTransform", out transformObject);
                    break;
            }

so my question is, how do I do that with lightinject within Umbraco8 ? ...

I am hoping I can stick with Autofac to be consistent with my Umbraco7 project. Will be a little confused if I need to change the DI to sit with lighinject (seeing Umbraco let us use our own DI packages).

Thanks ...
