How to use captcha botdetect in MVC Core 6.0?

Question

Hi I am trying to implement the captcha of botdetect in MVC Core 6. After a lots of search i don't find any solution for MVC Core 6. If Anyone have an idea for using on mvc 6.0 than tell me.

steps completed on my side are:

Installation of Captcha completed.

created a captchahelper class for for design implementation here is the code:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using BotDetect.Web.Mvc;

 namespace ePost.Common
 {
     public static class CaptchaHelper
     {
         public static MvcCaptcha GetRegistrationCaptcha()
         {
             // create the control instance
             MvcCaptcha registrationCaptcha = new MvcCaptcha("RegistrationCaptcha");
             // set up client-side processing of the Captcha code input textbox
             registrationCaptcha.UserInputID = "CaptchaCode";
             registrationCaptcha.HelpLinkEnabled = false;
             registrationCaptcha.HelpLinkText = "";
             registrationCaptcha.HelpLinkUrl = "#";
             // Captcha settings
             registrationCaptcha.ImageSize = new System.Drawing.Size(200, 50);
             registrationCaptcha.CodeLength = 4;

             return registrationCaptcha;
         }
         public static MvcCaptcha GetLoginCaptcha()
         {
             // create the control instance
             MvcCaptcha loginCaptcha = new MvcCaptcha("LoginCaptcha");

             // set up client-side processing of the Captcha code input textbox
             loginCaptcha.UserInputID = "CaptchaCode";
             loginCaptcha.HelpLinkEnabled = false;
             loginCaptcha.HelpLinkText = "";
             loginCaptcha.HelpLinkUrl = "#";
             // Captcha settings
             loginCaptcha.ImageSize = new System.Drawing.Size(200, 50);
             loginCaptcha.CodeLength = 4;

             return loginCaptcha;

         }
     }
 }

Now i am trying to display this captcha on view with using this code:

@{ MvcCaptcha loginCaptcha = CaptchaHelper.GetLoginCaptcha(); }

                  @Html.Captcha(loginCaptcha)        

                   <div class="form-card">
                       <div class="mt-4" style="margin-bottom:-40px;">
                           <label for="captchareg" class="fieldlabels">Type Above Code:</label>
                           <input asp-for="CaptchaCode" class="form-input captchaVal valid space-not textbox" id="captchareg" maxlength="10" />
                           <span class="b-placeholderreg">Type Above Code</span>
                           <span asp-validation-for="CaptchaCode" class="text-danger"></span>
                       </div>
                   </div>
               </fieldset>

@Html.Captcha(loginCaptcha) this line of code is working on normal MVC but it is not working in MVC core 6. Am i missing something please tell me. is there any need to inject this captcha service in program.cs file than please tell me.

If Anyone have a aolution for this please tell me.

Juding from the namespace using BotDetect.Web.Mvc; you referred, you codes were for Asp.Net(Not core), you have to find a solution for .net core
