Answer 1

Thanks for posting your follow-up answer. I got this same error after installing jQuery.UI to a new ASP.NET web forms project based on the new One ASP.NET template in VS.NET 2013 and adding this line to the script manager in the master page:

<asp:ScriptReference Name="jquery.ui.combined" />

After installing the AspNet.ScriptManager.jQuery.UI.Combined NuGet package as you stated, the error was immediately resolved.

Answer 2

Add this to your Web.config and the issue will be resolved:

<appSettings>
<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>

By the way guys, I was able to resolve this by installing the AspNet.ScriptManager.jQuery.UI.Combined and AspNet.ScriptManager.jQuery packages using the Nuget tool.
