Closed Issue: New Ajax Toolkit throwing error with AjaxControlToolkit.WCSFExtensions.dll [22767]

We are using serverside validation extender (ajaxcontroltoolkit.WCSFextensions.dll) in my project which requires ajax control toolkit v 3.0.11119.25533. Now we are also using html editor control present in the new ajax control tollkit v 3.0.30512.17815.

Now while integrating we are unable to use them together as both have same namespace and assemblyname.

Could you please guide us ?

It seems that a class 'AjaxControlToolkit.ExtenderControlBase' is present in the earlier toolkit but not in the present one.

Thanks and regards
