How to Create captcha in asp.net core Asp.net Mvc 6?
<p>I am developing asp.net MVC 6 application in asp.net core , and i want to create a captcha for my login page. in previous .net frameworks i used the system.drawing to create a captcha but since in .net framework core we dont have system.drawing , how can i achieve this ?</p>

<p>one solution is to reference full .net framework but this is not what i want. i want to use the core framework.</p>

<p>another one is to create a project with .net framework 6 and Mvc 5 and use a web api to get the captcha image , but also this is not what i want.</p>

<p>is there another solution ? </p>
