Convert Codeigniter .htaccess file to equivallent web.config file for IIS 8

I have locally developed project using codeigniter framework and Xampp apache server, url redirection is on and rewrite rules are defined in .htaccess file and working properly, here is my .htaccess file:

RewriteEngine On
RewriteBase /myproject
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]

now suddenly client requirement has changed and he wants all windows environment, instead of apache he suggested to use IIS, so i have to move to IIS. Same project with little modifications is running and redirecting default controller which is defined in routes.php file but my other redirections are not working. I searched and found that .htaccess file does not work on IIS need to convert .htaccess file to web.config however i tried to convert my .htaccess to web.config as follows :

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
    <rewrite>
        <rules>
            <rule name="MyRule">
                <match url="^(.*)$" /> 
                    <conditions> 
                         <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> 
                         <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> 
                    </conditions> 
                    <action type="Rewrite" url="index.php/{R:1}" appendQueryString="false" />
             </rule>
        </rules>
    </rewrite>
</system.webServer>
</configuration> 

But this does work,giving following error:

HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid.

Detailed Error Information:
