Google Recaptcha in ASP.net 4.7.2

I am trying to install Recaptcha in my project. In order to accomplish that, I downloaded

 recaptcha-dotnet-1.0.5.0-binary.zip

from here

https://code.google.com/archive/p/recaptcha/downloads

I unzipped the zip file and placed the Recpatcha in my project references:

I added Recaptcha in my asp.net page like so:

enter image description here

I put the below tag in my asp.net web form

  <%@ Register TagPrefix="recaptcha" Namespace="Recaptcha" Assembly="Recaptcha" %>

then I added the code in my aspx page like so:

<form id="form1" runat="server">
        <div>

          <recaptcha:RecaptchaControl
              ID="recaptcha"
              runat="server"
              Theme="red"
              PublicKey="xxxx"
              PrivateKey="xxxxx"
              />

          <asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" style="height: 26px" />
        </div>
    </form>

when I run the asp.net application by pressing F5. I don't see anything on my web page except the submit button:

enter image description here

I am not sure what am I doing wrong and how can I see Recaptcha.

I also followed this article :

https://www.codeproject.com/Tips/884193/Google-ReCaptcha-ASP-net-Control

and put the same GoogleREcaptcha that is mentioned in the article. I am getting the following error if I use the same dll as mentioned in the article

enter image description here

Any help will be highly appreciated.

Where is your code-behind? In any case, there are three versions of the Google ReCaptcha. Version 1.0 which you are using from an old archive is deprecated. At a minimum you should be using version 2.0

Here is an article which I often refer to when adding ReCaptcha 2.0 to Web Forms projects. If you follow these steps it should work for you:

Google ReCaptcha 2.0 - ASP.NET Control

Bear in mind the the keys you register for your live site will not work on your local machine. You can obtain free dev keys for developing locally.
