[Solved] Cross-Origin XMLHttpRequest in .Net Web application

Hello guys,
I guess most of you have faced this kind of problem where an error of this kind written in console
"Cross-Origin XMLHttpRequest is blocked due to security reasons"
 when you are either calling a webservice or webapi from a different origin in your project/solution.
Actually it simply means that your browser has blocked the XMLHttpRequest because your current application has different origin compared to originating Webapi or Webservice.

A simple solution to this is try to add these lines in your webconfig file which will allow the cross-origin XMLHttpRequest by your browser by default.

<system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*"/>
      </customHeaders>
    </httpProtocol>

<system.webServer>

thanks. Have a nice day
