How to redirect from http to https in ASP.NET Core?

In asp.net core, you can set up a redirect from HTTP to HTTPS on the web-server or use middleware Rewrite in your startup.cs 

  var options = new RewriteOptions()
                .AddRedirectToHttps(StatusCodes.Status301MovedPermanently, 44384);
 
            app.UseRewriter(options);

Complete code would look like this

 public void Configure(
            IApplicationBuilder app, 
            IHostingEnvironment env)
        {
            var options = new RewriteOptions()
                .AddRedirectToHttps(StatusCodes.Status301MovedPermanently, 44384);
 
            app.UseRewriter(options);
 
            app.UseMvcWithDefaultRoute();
        }

In startup.cs you can configure Https redirect by using code below

public void ConfigureServices(
            IServiceCollection services)
        {
            //add the MVC filter for https 
            services.AddMvc(options =>
            {
                options.Filters.Add(new RequireHttpsAttribute());
            });
        }
