An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.(the project does not even run locally)

This same question was posted in the site and the suggested answer was to use.

<configuration>
    <system.webServer>
        <validation validateIntegratedModeConfiguration="false" />
    </system.webServer>
</configuration>

but adding the above mentioned line does not solve the issue.

Most likely cause

• This application defines configuration in the system.web/httpHandlers section.

And

Module     ConfigurationValidationModule
Notification       BeginRequest
Handler    ExtensionlessUrlHandler-Integrated-4.0
Error Code     0x80070032

moreover my project does not seem to load locally as well, where as the question i mentioned earlier worked fine locally.

How do i Solve this error?

Thank you in advance. :)

Removing the following line from the web.config file fixed the issue for me.

<system.web>
    <httpHandlers>
      <add path="*.less" verb="GET" type="dotless.Core.LessCssHttpHandler, dotless.Core" />
    </httpHandlers>
  </system.web>
