I’m writing this post for myself, so everyone else can stop reading now if you like. Although you might find it useful, who knows.
Why am I talking to myself? Because today I came across the error in the title, and thought “Hmm I’ve not seen that one before”, only to plug it into Google and to have my browser tell me I’d already visited the first 5 results for that search previously.
Increasing age, you’re a cruel mistress.
None of those results applied to my situation at all, and I’m hoping that writing this post will save me some time in future, so here goes.
This issue can also occur when you’ve upgraded a site (usually running a product), and have some old DLLs lying around. In this case, some refactoring had occurred to the product, and there was an old DLL lurking around that was causing the error above under certain situations. So the solution was simply to look closely, clean up the references and bin directories, and then all is well.
Ross, if you’re reading this in the future, then you really should consider investing in some memory exercises, or, to take more care with those product upgrades. Seriously.
About me
My name is Ross Hawkins and I'm a developer, consultant, business owner and writer based in Auckland,

SQL Server, and a mix of other Microsoft development technologies.
I also have about 15 years of experience with IBM Lotus Notes/Domino and associated technologies. While Notes/Domino
is no longer my primary focus I still like to dabble and keep my skills up to date.

Microsoft AJAX Extensions: Sys.Debug is null or not an object
One of the breaking changes which was made with
the 1.0 release of the Microsoft Ajax Extensions was the renaming
of the 'Debug' class to 'Sys.Debug' for reasons of compatiability
with other frameworks. Breaking changes like this can often be a source of frustration..

Simple ASP.NET Character Counter
A textbox character counter is a pretty simple piece of functionality, and there's a lot of different ways to apply one to your application.
