Extending your SharePoint 2007 site with Microsoft ASP.NET AJAX 3.5

After ASP.NET 3.5 has been installed you need to modify the
web.config file of your MOSS web site with a few Ajax specific
entries. Typically, the web.config file is located in
c:\inetpub\wwwroot\wss\virtualdirectories\80

1. Add the following <sectionGroup> element in the
<configSections> tag:

<sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup,

    System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

    <sectionGroup name="scripting" type="System.Web.Configuration.ScriptingSectionGroup,

        System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

        <section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection,

            System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"

            requirePermission="false" allowDefinition="MachineToApplication"/>

        <sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup,

            System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

            <section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection,

                System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"

                requirePermission="false" allowDefinition="Everywhere" />

            <section name="profileService" type="System.Web.Configuration.ScriptingProfileServiceSection,

                System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"

                requirePermission="false" allowDefinition="MachineToApplication" />

            <section name="authenticationService" type="System.Web.Configuration.ScriptingAuthenticationServiceSection,

                System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"

                requirePermission="false" allowDefinition="MachineToApplication" />

            <section name="roleService" type="System.Web.Configuration.ScriptingRoleServiceSection,

                System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"

                requirePermission="false" allowDefinition="MachineToApplication" />

        </sectionGroup>

    </sectionGroup>

</sectionGroup>

2. Add the following <controls> section as a child of the
<system.web>/<pages> tag:

<controls>

    <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral,

        PublicKeyToken=31BF3856AD364E35"/>

    <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral,

        PublicKeyToken=31BF3856AD364E35"/>

</controls>

3. Add the following tag to the <assemblies> tag, within
the <compilation> element:

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

<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"/>

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

4. Register the following HTTP handlers at the end of the
<httpHandlers> section:

<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"/>

5. Add the following HTTP module registration to the
<httpModules> section beneath any existing modules:

<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions,

    Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

6. Add a SafeControl entry for the System.Web.UI namespace from the
System.Web.Extensions assembly within the
<SharePoint>/<SafeControls> section:

<SafeControl Assembly="System.Web.Silverlight,

           Version=2.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

           Namespace="System.Web.UI.SilverlightControls" TypeName="*" Safe="True" />

<SafeControl Assembly="System.Web.Extensions,

           Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

           Namespace="System.Web.UI" TypeName="*" Safe="True" />

7. Since the RadEditor dll files, which are in the wsp package, are
complied for .NET 2.0 framework, you need to add the following code to the
<runtime><assemblyBinding> section.

<dependentAssembly>

    <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35"/>

    <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>

</dependentAssembly>

<dependentAssembly>

    <assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35"/>

    <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>

</dependentAssembly>

8. Finally, add the following configuration tags at the bottom of
web.config, just before the end of the <configuration> tag:

<system.web.extensions>

     <scripting>

     <webServices>

     </webServices>

     </scripting>

 </system.web.extensions>

 <system.webServer>

   <validation validateIntegratedModeConfiguration="false"/>

   <modules>

     <remove name="ScriptModule" />

     <add name="ScriptModule" preCondition="managedHandler"

        type="System.Web.Handlers.ScriptModule,

        System.Web.Extensions, Version=3.5.0.0, Culture=neutral,

        PublicKeyToken=31BF3856AD364E35"/>

   </modules>

   <handlers>

     <remove name="WebServiceHandlerFactory-Integrated"/>

     <remove name="ScriptHandlerFactory" />

     <remove name="ScriptHandlerFactoryAppServices" />

     <remove name="ScriptResource" />

     <add name="ScriptHandlerFactory" verb="*" path="*.asmx"

        preCondition="integratedMode"

        type="System.Web.Script.Services.ScriptHandlerFactory,

        System.Web.Extensions, Version=3.5.0.0, Culture=neutral,

        PublicKeyToken=31BF3856AD364E35"/>

     <add name="ScriptHandlerFactoryAppServices" verb="*"

        path="*_AppService.axd"

        preCondition="integratedMode"

        type="System.Web.Script.Services.ScriptHandlerFactory,

        System.Web.Extensions, Version=3.5.0.0, Culture=neutral,

        PublicKeyToken=31BF3856AD364E35"/>

     <add name="ScriptResource" preCondition="integratedMode"

        verb="GET,HEAD" path="ScriptResource.axd"

        type="System.Web.Handlers.ScriptResourceHandler,

        System.Web.Extensions, Version=3.5.0.0, Culture=neutral,

        PublicKeyToken=31BF3856AD364E35" />

   </handlers>

</system.webServer>
