How to use Windsor IoC in ASP.net Core 2

How can I use Castle Windsor as an IOC instead of the default .net core IOC container?

I have built a service resolver that depends on WindsorContainer to resolve services.

Something like:

public class ServiceResolver
{
    private static WindsorContainer container;
    public ServiceResolver()
    {
        container = new WindsorContainer();
        // a method to register components in container
        RegisterComponents(container);
    }

    public IList<T> ResolveAll<T>()
    {
        return container.ResolveAll<T>().ToList();
    }
}

Can not figure out how to let my .net core 2 web API use this resolver as a replacement for IServiceCollection.

For others Reference In addition to the solution Nkosi provided.

There is a nuget package called Castle.Windsor.MsDependencyInjection that will provide you with the following method:

WindsorRegistrationHelper.CreateServiceProvider(WindsorContainer,IServiceCollection);

Which's returned type is IServiceProvider and you will not need to create you own wrapper.

So the solution will be like:

public class ServiceResolver{    
    private static WindsorContainer container;
    private static IServiceProvider serviceProvider;

    public ServiceResolver(IServiceCollection services) {
        container = new WindsorContainer();
        //Register your components in container
        //then
        serviceProvider = WindsorRegistrationHelper.CreateServiceProvider(container, services);
    }

    public IServiceProvider GetServiceProvider() {
        return serviceProvider;
    }    
}

and in Startup...

public IServiceProvider ConfigureServices(IServiceCollection services) {
    services.AddMvc();
    // Add other framework services

    // Add custom provider
    var container = new ServiceResolver(services).GetServiceProvider();
    return container;
}
