Problem with C# SDK ver 5 -

I'm trying to run the MVC website sample and running into this problem; Microsoft JScript runtime error: Syntax error in regular expression

var a=document.cookie.match('\\bfbs_'+FB._apiKey+'="([^;]*)\\b'

What am I dong w开发者_JAVA百科rong ??

The document.cookie.match() is unclosed. There seems to be a trailing " that isn't present (at a guess) and also the FB._apiKey may contain some reserved characters that need escaping.
