AjaxControlToolkit.dll major version mismatch

Hi,

When I go to "create a post" under blogs, I get the following error:

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)

I tried binding the assembly to the older version by adding the following line in web.config, however no luck so far.

<bindingRedirect oldVersion="3.0.20820.16598" newVersion="4.1.40412.2"/>

Any ideas are welcome.

Hello Consumentenclaim,

Can you please try configuring the binding redirect like this in your web.config (please include this before the closing </configuration> tag):

Hi,

That is exactly identical to what I currently have in my web.config. To make sure I copy-pasted but still no luck.

Any ideas are highly appreciated.

Hi,

If you have set the binding redirect in your web.config, then there should be no particular reason for the exception that's being thrown, since even if there is a control that's explicitly requiring the older version of your
AjaxControlToolkit.dl it will be redirected to the newer version. Can you please verify that the project reference to that assembly is correct, and if replacing it with the older version will change the experienced issue. If any problems persist, maybe we could arrange you sending us your project's files and a backup of its database, so we can study it further, as we are not able to reproduce this issue locally.

We are also seeing this exception with AjaxControlToolkit 4.1. We have entered the binding redirect in the web.config but that is no help. We still get the binding exception.

Update...

Hi Keith,
