Closed Issue: AJAX toolkit upgrade to 3.0.30512.20351, but still seeing lot of errors "Could not load file or assembly 'AjaxControlToolkit, Version=3.0.20820.16598, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' or one of its dependencies." [23261]

We just upgraded our AJAX tool kit from AJAXcontrolToolkit version 3.0.20820.16598 to 3.0.30512.20351 to use the HTML Editor Control. But once after upgrade we are seeing some wiered errors on our log.
"Could not load file or assembly 'AjaxControlToolkit, Version=3.0.20820.16598, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) "

After some research we figured out the rootcause might be the Google Cached pages still have the below script tag created by AJAX Toolkit, which refers to the older version.

<script src="/item.aspx?_TSM_HiddenField_=ctl00_ScriptManager1_HiddenField&amp;_TSM_CombinedScripts_=%3b%3bAjaxControlToolkit%2c+Version%3d3.0.20820.16598%2c+Culture%3dneutral%2c+PublicKeyToken%3d28f01b0e84b6d53e%3aen-US%3a707835dd-fa4b-41d1-89e7-6df5d518ffb5%3a9ea3f0e2%3ae2e86ef9%3ac7c04611%3a1df13a87%3acd120801%3ac4c00916%3a3858419b%3a96741c43%3a38ec41c0" type="text/javascript"></script>

1. Why does the AJAXToolkit writes the version number on the script elements
2. Is there anyway to resolve the above errors.

Thanks
