    <!-- Due to known error (http://stackoverflow.com/questions/12576662/msdeploy-skip-rules-when-using-msbuild-publishprofile-with-visual-studio-2012)
    we should use MsDeployExe for delivery, if we want to skip only several folders  
    And as we are skipping SeoChecker.config update - we shall use it always-->
    <UseMsDeployExe>true</UseMsDeployExe>
