Answer 1

In ASPNET CORE 2.0, The following works for me

   public void ConfigureServices(IServiceCollection services)
    {

        services.Configure(options =>
        {
            options.Filters.Add(new CorsAuthorizationFilterFactory("AllowSpecificOrigin"));
        });
        services.AddCors(options =>
        {
            options.AddPolicy("AllowSpecificOrigin",
                builder => builder.WithOrigins("http://localhost:5000").AllowAnyHeader()
                .AllowAnyMethod());
        });

        services.AddMvc()
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {

        loggerFactory.AddConsole();
        loggerFactory.AddDebug(LogLevel.Information);

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        // Shows UseCors with named policy.
        app.UseCors("AllowSpecificOrigin");

        app.UseStaticFiles();
        app.UseAuthentication();


        app.UseMvcWithDefaultRoute();
    }
}
