I'm getting a file not found (stack trace below) for Kendo.Mvc.resources while trying to add 2016.2.504 to an MVC6 project.

I installed the Kendo.MVC nuget package from the private feed

-- https://nuget.telerik.com/nuget

I also installed the bower package from

-- "kendo-ui": "https://bower.telerik.com/bower-kendo-ui.git#~2016.2.504"

I also added all the manual steps from http://docs.telerik.com/kendo-ui/aspnet-mvc/mvc-6/getting-started

Hello,

Thanks for the detailed bug report.

From the stack trace I can see that the DatePicker widget is trying to read the exception message for an "Rtl" exception and fails.
We'll investigate why the exception message is not available in the resource file.

This is the message that should be displayed:
The "{0}" class is no longer supported. To enable RTL support you must include telerik.rtl.css and apply the "t-rtl" class to a parent HTML element or the <body>.

And this is the code throwing it:
public virtual void VerifySettings()
{
if (!Name.Contains("<#=") && Name.IndexOf(" ") != -1)
{
throw new InvalidOperationException(Resources.Exceptions.NameCannotContainSpaces);
}

((IHtmlAttributesContainer) this).ThrowIfClassIsPresent("k-" + GetType().Name.ToLowerInvariant() + "-rtl", Resources.Exceptions.Rtl);
}

Try removing the k-datepicker-rtl class, if it is set via HtmlAttributes.

I hope this helps.
