Have an issue where I get this error in IE (10) and Chrome, but not in Firefox. I've verified that I have 4.1.7.725. I've checked all my options to ensure all references are correct. Checked web config. I'm just missing something cause while I have the correct ajaxcontroltoolkit DLL, it's not being recognized by IE and Chrome. I have this in my web.config:
```
<add assembly="AjaxControlToolkit, Version=4.1.7.725, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e" />
```
Thoughts anyone?

Comments: Hi, I'm currently having same problem. I built my website on .Net 4.0 framework. Funny thing is when I start my website on Visual Studio it works perfectly. But When I upload it to my IIS 8 local host, it shows that error. I installed AjaxControlToolKit to GAC. That finds .dll files but shows that illogical error. So please somebody explain what we are doing wrong ?
