Visual Studio 2013 Javascript无法识别“ <％=％>”吗？

Question

When I am upgrading from Visual Studio 2010 to Visual Studio 2013. The code in Javascript in VS 2010 shown red text in between ' ' and the website is working fine,

id = '<%= Company.NEAt.GetUserID().ToString() %>';

But in VS 2013, it doesn't show red text in between ' ' and I got error on website saying,

System.NullReferenceException: Object reference not set to an instance of an object.

Anyone know why?

Answer 1

I found a solution that I wasn't expecting.

All I had to do is disable anonymous Authentication in IIS and it worked fine. It because this code is waiting to get window authentication, not anonymous.
