Getting a .NET 2.0+AJAX working on Win2008+IIS7

Hi,

I'm on DASP with Win2008+IIS7 hosting. I'm trying to get a .NET 2.0+AJAX site working but am getting an error regarding the assembly "System.Web.Extensions, Version=1.0.61025.0 ...". I have this assembly referenced in my web.config. I believe it is for AJAX. I've read in another post that v1.xxxxx of this assembly is not supported in IIS7. If so, anyone know the correct config I need for my web.config to work on DASP?

Thanks in advance! ..sa

Hi,
Are you using Visual Studio? If so, did you let it create the updated web.config sections?
You should have a section like this:

<!--
The system.webServer section is required for running ASP.NET AJAX under Internet
Information Services 7.0. It is not necessary for previous version of IIS.
-->
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>

<add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

Thanks for the replies.

My project is from VWD 2005 and designed to run on IIS 6/.NET 2.0. I'm planning on migrating it to IIS7/.NET 3.5 but before doing so, I would like to first get it running on IIS7/.NET 2.0.

I've been doing a lot of research on migrating .NET 2.0 to 3.5 and IIS 6 to 7. I'm guessing that the problem I've described is due to incorrect web.config entries (particularly for AJAX). If anyone has any other suggestions that might work, please let me know. Otherwise, I think I have no other choice but to migrate to 3.5 immediately!

Thanks again. ..sa

 

Hi,
If you want I can create a basic Ajax page for IIS7 with the default web.config, ZIP it up and you can see it running on a DASP server then D/L it.
Salute,
Mark

 

Thx, mark. It's okay; I've started my migration to 3.5 and used the web.config that VWD 2008 had converted for me. I'm no longer getting the assembly reference error. Instead, I'm dealing with other migration nightmares!

Thanks all. ..sa

 

Good job ;-)

 

That can be painful, for sure, but you'll be glad you did it in the long run.
