Hello, Barry!

Callstack indicates that exception was thrown from .NET Framework code.
No wonder you cannot find the line that throws the exception.

Callstack also "says" that there was NullReferenceException in the
System.Web.UI.Control.ResolveClientUrl(...) and that HtmlLink control is
being rendered.

Try using the web deployment project before testing again. And make sure it
creates the PDB file, so you can see where the issue is.

As it stands, the exception is thrown high up the stack, but without seeing
your code, I could not even guess what is causing the issue.
