Ajax & Linq Enable WSS 3.0 and MOSS 2007

In order to use the UC Logic SharePoint Web Parts, firms will need to enable SharePoint's support for both Ajax 3.5 and Linq. Whilst Microsoft provided support for these technologies in SharePoint 2007 SP1, firms need to make the relevant changes in the web.config file used by SharePoint to activate them. In a single server implementation this file will be located at c:\inetpub\wwwroot\wss\virtualdirectories\80. In multi-server Farms, these changes must be made to all servers in the Farm that will host our web parts.

Step 1. Upgrade to ASP.Net 3.5 SP1 or higher

If your server is not running the latest version of ASP.NET, download and install the .Net 3.5 framework from Microsoft: http://www.microsoft.com/downloads/details.aspx?familyid=AB99342F-5D1A-413D-8319-81DA479AB0D7&displaylang=en.

Step 2. Ajax Enable SharePoint

We would like to thank Mike Ammerlaan for his original posting on Ajax Enabling WSS which can be found here: http://sharepoint.microsoft.com/blogs/mike/Lists/Posts/Post.aspx?ID=3. Extending SharePoint web.config files with ASP.NET AJAX requires that you interleave some Ajax registration entries in-line with WSS registration entries. To do this you will need to edit your SharePoint web.config file, typically in a directory like c:\inetpub\wwwroot\wss\virtualdirectories\80.

If not already present, add the following <sectionGroup>element to the <configSections>tag:

Add a <controls> section as a child of the <system.web>/<pages>

    <pages>
      <controls>
        <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      </controls>
    </pages>

If not already present, add the following tag to the <assemblies> tag, within <compilation>:

      <assemblies>
       <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      </assemblies>

Add some new registrations to the end of the <httpHandlers> section:

<httpHandlers>
      <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
</httpHandlers>

Step 3. Linq Enable SharePoint

This involves further additions to the web.config file:

Add the following inside of the <assemblies> tag block:

Add the following before the end of the file:

<system.codedom>

</compiler>

</compiler>

</compilers>

</system.codedom>
