Hi,

I've used the models builder to generate the document types as models within the solution, setting the config to "LiveAppData"

I've set some as compositions, so I can then inject them in custom services, as there are generated as interfaces as well.

When injecting these into a custom service, I get following error:

    Boot failed: Umbraco cannot run. See Umbraco's log file for more details.

    -> Umbraco.Core.Exceptions.BootFailedException: Boot failed.

    -> System.InvalidOperationException: Unable to resolve type: Umbraco.Core.Composing.ComponentCollection, service name:   at LightInject.ServiceContainer.CreateDelegate(Type serviceType, String serviceName, Boolean throwError)   at LightInject.ServiceContainer.CreateDefaultDelegate(Type serviceType, Boolean throwError)   at LightInject.ServiceContainer.GetInstance(Type serviceType)   at Umbraco.Core.FactoryExtensions.GetInstance[T](IFactory factory)   at Umbraco.Core.Runtime.CoreRuntime.Boot(IRegister register, DisposableTimer timer)

In previous versions, I would get the data of the page via the interface, through a generic class where it gets the Id as well - the Umbraco 8 version of that code also threw the same error as above.

Is there a way for me to successfully inject these interfaces and use them in my custom service class?

I'm injecting as the following:

    private readonly IMicrosoftGraphApicomposition _microsoftGraphApi;
    public GraphService(ILogger logger, IMicrosoftGraphApicomposition microsoftGraphApi)
    {
        _logger = logger;
        _microsoftGraphApi = microsoftGraphApi;
    }

Thanks

As a workaround, I'm using the Concrete model and getting the path based on the alias of the document type to get the values of the item:

    var publishedContent = Umbraco.Web.Composing.Current.UmbracoHelper.ContentSingleAtXPath("//"+MicrosoftGraphApi.ModelTypeAlias);
    var microsoftGraphApisettings = new MicrosoftGraphApi(publishedContent);
