I've got a number of modules written against .NET 2.0 on our DNN 4.9.x installation. Lately, I decided to upgrade one of them to 3.5 so I could use the new Charts controls but now all of my modules using UpdatePanels with 2.0 are broken. DotNetNuke.Services.Exceptions.ModuleLoadException: c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\5badfcee\f17ac744\App_Web_basicinfo.ascx.97730825.sg8lzai6.0.cs(8127): error CS0433: The type 'System.Web.UI.UpdatePanel' exists in both 'c:\WINDOWS\assembly\GAC_MSIL\System.Web.Extensions\3.5.0.0__31bf3856ad364e35\System.Web.Extensions.dll' and 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\5badfcee\f17ac744\assembly\dl3\69975b21\004187ac_515cc701\System.Web.Extensions.DLL' Is it possible to run modules using either framework or do I need to recompile all of my 2.0 modules against 3.5?

Generally when  see this is when you are running DNN 4.x and have a Ajax/.Net 3.5 module installed.  The fix is to update DNN to use the latest version (3.5) and then allow it to pass the calls for an older framework.

To do this, follow the instructions below:

  1. Backup your Database and Site (files)
  2. Delete the Systme.Web.Exteansions.dll from the portals Bin directory
  3. Open the Web.Config and do a find and replace on "1.0.61025.0" changing it to "3.5.0.0"
  4. Save your changes and try the site again

I hope this helps.

<p>But then my 2.0 modules lose their reference for UpdatePanels.&#160; Do I&#160;need to convert them all to 3.5 so they can reference the newer System.Web.Extensions?</p>

They should not loose anything.  What error do you get from them after you make the changes above?

I fixed this last week and forgot to update this thread:

I needed to add this to the <assemblyBinding> section of my web.config

<dependentAssembly>
   
<assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35"/>
   
<bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
</dependentAssembly>
