Syntax error on javascript due to conversion VS2008 to VS2012

Recently I installed visual studio 2012. I converted my project in the log it seems to be fine, No errors. When I look in the code in the javascript at the end of the sentence he marks the ; red and gives the error: "syntax error". Weirdly of all the line of code still works but I only get this error in VS2012 and not in VS2008. The projects still builds because this is javascript. Any idea why this is marked as an error in VS2012?

public string getJsonSiteIDs()
        {   //list to javascript for autocorrect on site id's
            return (new JavaScriptSerializer()).Serialize(siteIdsList.Distinct().ToList());
        }

        public string getJsonCountries()
        {   //list to javascript for autocorrect on countries
            return (new JavaScriptSerializer()).Serialize(countryList.Distinct().ToList());
        }
