c# How to Inject dependency on a custom handler for WebAPI using ninject

Question

I have the following handler for my c# WebAPI project.

public class CustomLogHandler : DelegatingHandler
    {
        [Inject]
        public ILogRepository LogRepository { get; set; }

        ... some methods here   
     }

This handler is registered in my WebApiConfig.cs class.

public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services

            // Web API routes
            config.MapHttpAttributeRoutes();

            ... some code here

            config.MessageHandlers.Add(new CustomLogHandler());
        }
}

Also my ILogRepository is registered in my NinjectWebCommon.cs class as my other repositories:

 kernel.Bind(typeof(ILogRepository)).To(typeof(Data.LogRepository));

The problem is that when I debug and the breakpoint hits my CustomLogHandler method, LogRepository instance is null.

Any clue?

Register the handler with the kernel as well and then resolve the instance before adding it to the handler collection — Nkosi, Jul 29 '18 at 18:07

I found a way that works great:

var service = GlobalConfiguration.Configuration.DependencyResolver.GetService(typeof(ILogRepository)) as ILogRepository;

Hope this works for someone else.

Thanks
