The parameterless constructor is needed, but AFAIK never used.

So if you add your parameterless constructor, and assign Current.Logger to your logger property, then you should be good to go. At least, that is how I have solved this...

I will try this again.

I did add both a parameterless constructor and one with the ILogger param. But it always used the parameterless constructor..

This does not work. The system will not resolve the dependency for ILogger:

-> System.InvalidOperationException: Unresolved dependency [Target Type: XXX.Core.Events.NotifyWhenMemberApprovedComponent], [Parameter: logger(ClientDependency.Core.Logging.ILogger)], [Requested dependency: ServiceType:ClientDependency.Core.Logging.ILogger, ServiceName:] at LightInject.ServiceContainer.GetEmitMethodForDependency(Dependency dependency) in C:\projects\lightinject\src\LightInject\LightInject.cs:line 4207 at LightInject.ServiceContainer.EmitConstructorDependency(IEmitter emitter, Dependency dependency) in C:\projects\lightinject\src\LightInject\LightInject.cs:line 4154 at LightInject.ServiceContainer.EmitConstructorDependencies(ConstructionInfo constructionInfo, IEmitter emitter, Action1 decoratorTargetEmitter) in C:\projects\lightinject\src\LightInject\LightInject.cs:line 4120 at LightInject.ServiceContainer.EmitNewInstanceUsingImplementingType(IEmitter emitter, ConstructionInfo constructionInfo, Action1 decoratorTargetEmitMethod) in C:\projects\lightinject\src\LightInject\LightInject.cs:line 4081 at LightInject.ServiceContainer.EmitNewInstance(ServiceRegistration serviceRegistration, IEmitter emitter) in C:\projects\lightinject\src\LightInject\LightInject.cs:line 4038 at LightInject.ServiceContainer.<>cDisplayClass153_0.0(IEmitter ms) in C:\projects\lightinject\src\LightInject\LightInject.cs:line 3856 at LightInject.ServiceContainer.CreateDynamicMethodDelegate(Action`1 serviceEmitter) in C:\projects\lightinject\src\LightInject\LightInject.cs:line 3777 at LightInject.ServiceContainer.CreateDelegate(Type serviceType, String serviceName, Boolean throwError) in C:\projects\lightinject\src\LightInject\LightInject.cs:line 4743

public class NotifyWhenMemberApprovedComponent : IComponent
{
    private readonly ILogger _logger;
    private readonly IScopeProvider _scopeProvider;

    public NotifyWhenMemberApprovedComponent(ILogger logger, IScopeProvider scopeProvider)
    {
        _logger = logger;
        _scopeProvider = scopeProvider;
    }

...

I have solved the problem

The issue was that I had imported the wrong namespace for ILogger. I am now correctly using using Umbraco.Core.Logging.

I'll go away and shout at myself for a few hours...

is working on a reply...
