Why is my custom HTML Helper result getting html encoded?

I've got the following custom html helper in asp.net mvc 3

public static string RegisterJS(this HtmlHelper helper, ScriptLibrary scriptLib)
{
   return "<script type=\"text/javascript\"></script>\r\n";
}

The problem is that the result is getting html encoded like so (I had t开发者_Go百科o add spaces to get so to show the result properly:

   <script type="text/javascript"></script>

This obviously isn't much help to me.. Nothing I've read says anything about this.. any thoughts on how I can get my real result back?

You're calling the helper in a Razor @ block or an ASPX <%: %> block.
These constructs automatically escape their output.

You need to change the helper to return an HtmlString, which will not be escaped:

return new HtmlString("<script ...");
