AjaxControlToolkit under medium trust

Is it the case that the current version of ToolkitScriptManager cannot run under medium trust?

If so, is there any intention to fix this?

For days I've been trying to update my website from ASP.Net 3.5 using toolkit version 3.5.40412.2. I thought the error (System.Reflection.ReflectionTypeLoadException) was due to some incompleteness of my updating of references. But now it's looking like the ToolkitScriptManager simply can't run under medium trust.

Any help?
