Hello,

 I'm trying to publish my website on a IIS server. The server has .Net FrameWork 2.0 and 3.5 installed.
The asp.net service is enabled for the IIS, the version is set to 2.0.

My Application has also been published for 3.5 framework. It uses some of the AJAX Toolkit extenders. I simply did a build > Publish Website en copied it to the folder of the website on the IIS.

 This is the error i'm getting:

Parser Error Message: Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.



I can't find what I'm doing wrong.

I found several possible solutions on this forum and the internet, I did those workarounds, but none worked.

Help would be greatly appreciated.

Open web.config file.
Press Ctrl+f and then type <assemblies>.
Inside the <assemblies> tag just ttype the follwoing line

<add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>

Even after adding the following line if it still gives error then add the following code also inside the <assemblies> tag:

<add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
                <add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
