Debugging is not supported under current trust level settings?

Today When I was debugging a test website I created for learning I got the error “Debugging is not supported under current trust level settings?”

This error normally occurs when you keep the website directly under C:\inetpub\wwwroot folder. Anyway that is not a subject here. We will directly go to the simple solution to resolve the issue.

Open your Web.config and add below line in

<system.web>
    <trust level="Full"/> 
    .....
    .....
</system.web>
