I am getting the same error message on my dev machine,

However, other AJAX controls work fine (CalendarExtender, MaskedEdit)...

I cannot use a MaskedEditValidator.

VS2010 SP1, on WinXP SP3.

Anyone have a solution to this issue ?

I wish this would be fixed soon. I really wish I could use the MaskedEditValidator.

I am having this error too and I have not found a solution that is valid yet. This is a source code error and the "experts keep wanting to resolve this either in Web Config or to make sure that you have AJAX installed. If the tool is available to use at this point it would seem like a logical conclusion that it is also installed.

I am getting the same error, but only occasionally. The rest of the Toolkit items work fine and the MaskedEdit works most of the time, too, this is a random event for my page.
