Is use of AntiXss library necessary/recommended in mvc 3 razor application

Is use of AntiXss library necess开发者_开发知识库ary/recommended in mvc 3 razor application? Where can I find out more about encoding options for mvc 3?

Razor automatically encodes the output to prevent XSS. If you need to output HTML mark-up then you can use the @Html.Raw(myVariable) method or make sure the variables you need to not be encoded are of type HtmlString.
