>I added the nugget package jquery ui and after install tried to use their accordion tool. I have verified via developer tools that to code.jquery.com are returning valid css and script. I coped most of the code from the jquery ui demo page.

>When run, I get the following error message on the call to: $("#accordion").accordion();
> Unhandled exception at line 99, column 21 in http://localhost:64779/Home/Index
> 0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'accordion'
