AjaxControlToolkit fails to run on Mono [closed]

问题

Running ASP.NET 3.5 on Mono 2.6.7 (Debian), AjaxControlToolkit throws the following exception on startup: "Cannot cast from source type to destination type." (see stack trace below) This is a simple website referencing AjaxControlToolkit (so long as it's referenced, it will fail throwing this exception).

On .NET 3.5, the same simple webpage referencing AjaxControlToolkit.dll would run fine.

How would you get this to run on Mono?
