LamarMissingRegistrationException - No Service registered

[zish82]

I am getting following error when i am registering simple asp.net core 2.1 app

An error occurred while starting the application. LamarMissingRegistrationException: No service registrations exist or can be derived for Microsoft.AspNetCore.Mvc.Internal.MvcRouteHandler

Lamar.IoC.Scope.GetInstance(Type serviceType)

I can see it's failing at UseMvc call in Configure method. Here is my Startup class

public class Startup { public Startup(IConfiguration configuration) { Configuration = configuration; }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    //public void ConfigureServices(IServiceCollection services)
    public void ConfigureContiner(IServiceCollection services)
    {
        services.Configure<CookiePolicyOptions>(options =>
        {
            // This lambda determines whether user consent for non-essential cookies is needed for a given request.
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });           

        services.AddMvcCore().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            app.UseHsts();
        }

        app.UseHttpsRedirection();
        app.UseStaticFiles();
        app.UseCookiePolicy();

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });
    }
}
