301 redirection - Trailing Slash web.config

Question

I want to do permanent 301 redirect from http://www.example.com/ to http://www.example.com .

I had tried below code in web.config, but not working. Is there anything other changes I have to do?

<rule name="SEO - Remove trailing slash" stopProcessing="false">
         <match url="(.*)/$" />
         <conditions>
           <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
           <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
         </conditions>
         <action type="Redirect" url="{R:1}" />
       </rule>

You don't need to redirect the root domain, read this
