Edit: While it still works, things changed a bit since I wrote this answer. Please check D.L.MAN's more up to date answer: https://stackoverflow.com/a/56800707/844207

In asp.net Core 2 you can use an URL Rewrite independent of the Web Server, by usingapp.UseRewriter in Startup.Configure, like this:

        if (env.IsDevelopment())        {            app.UseBrowserLink();            app.UseDeveloperExceptionPage();        }        else        {            app.UseExceptionHandler("/Home/Error");            // todo: replace with app.UseHsts(); once the feature will be stable            app.UseRewriter(new RewriteOptions().AddRedirectToHttps(StatusCodes.Status301MovedPermanently, 443));        }

Actually (ASP.NET Core 1.1) there is a middleware named Rewrite that includes a rule for what you are trying to do.

You can use it on Startup.cs like this:

var options = new RewriteOptions()    .AddRedirectToHttpsPermanent();app.UseRewriter(options);

In ASP.NET Core 2.2 you should use Startup.cs settings for redirect http to https

so add this in ConfigureServices:

public void ConfigureServices(IServiceCollection services){    services.AddHttpsRedirection(options =>    {        options.HttpsPort = 443;    });                           // <=== Add this (AddHttpsRedirection) =====    services.AddRazorPages();  }

and add this in Configure :

public void Configure(IApplicationBuilder app, IHostingEnvironment env){    if (env.IsDevelopment())    {        app.UseDeveloperExceptionPage();        app.UseDatabaseErrorPage();    }    else    {        app.UseExceptionHandler("/Home/Error");        app.UseHsts();            // <=== Add this =====    }    app.UseHttpsRedirection();    // <=== Add this =====}

in launchSettings.json check blow items exsits:

{  "iisSettings": {    "windowsAuthentication": false,    "anonymousAuthentication": true,    "iisExpress": {      "applicationUrl": "http://localhost:63278",      "sslPort": 44377      // <<===  check this port exists.    }  },  "YOUR_PROJECT_NAME": {      "commandName": "Project",      "dotnetRunMessages": "true",      "launchBrowser": true,      "applicationUrl": "https://localhost:5001;http://localhost:5000",  // <=== check https url exists.      "environmentVariables": {        "ASPNETCORE_ENVIRONMENT": "Development"      }    }  }}

then enjoy it.
