This issue is isolated to the jQuery Validate Javascript Library.

The script filename is: jquery.validate.unobtrusive.min.js

Although jQuery is Open Source, this library was provided by Microsoft (as indicated at the top of my js file):

/*
** Unobtrusive validation support library for jQuery and jQuery Validate
** Copyright (C) Microsoft Corporation. All rights reserved.
*/

Try replacing the library to use the replacement jquery.validate.min.js

One way is to use Visual Studio's NuGet Package Manager by the following:

  1. Right-click on your Project's References folder
  2. Select 'Add Library Package Reference...'
  3. When the window opens, Select 'Online' from the left sidebar menu.
  4. On the top-right, type in 'jquery.validate' and hit the enter key.
  5. Locate the 'jQuery Validation' and click the 'Install' button.
  6. Change your code to use the new library name 'jquery.validate.min.js'

I tested this and my client-side field validation all seems to work without the annoying exceptions when debugging in Visual Studio.

Unfortunately the source of the issue can't really be seen with this kind of error message. I would go over to Telerik.com and submit a runnable project, as well as steps to reproduce the issue, in a support ticket and have the support team take a look at the problem.
