Asynchronous error handling change in ASP.NET AJAX 3.5
There is a subtle change in the .NET 3.5 release of the Microsoft Ajax Library that might catch some developers by surprise when handling asynchronous postback errors. The change can be found at the end of the endPostBack function of the PageRequestManager object. In the first release of the Ajax library, if an error was not handled on the client; an alert box was used to convey to the user the error message:

ASP.NET 3.5 Extensions History Control Tip
Originally introduced in the ASP.NET Futures package, the history control in the ASP.NET 3.5 Extensions preview comes with a few nice additions. One of the updates is the ability to change the page title when adding a history point. This is important because without updating the title, the history list isn't very much help after a few updates. To illustrate the problem, here is what the history list in IE could look like after adding a few history points:

ASP.NET AJAX Role Application Service – Visual Studio 2008 (Orcas)
The first version ASP.NET AJAX gave us client-side support for two application services – profile and authentication. In Visual Studio 2008 (Orcas), an additional built-in service has been added: roles. If you’ve downloaded Eilon’s ASP.NET AJAX JavaScript Class Browser and installed the beta 2 (or beta 1) version of .NET 3.5, then you’ll find the new service under the Sys.Services namespace:
Adding support for the role service
If you’re upgrading an ASP.NET 2.0 web site to .NET 3.5 and want to leverage this new built-in service, you’ll have to make a few minor adjustments to web.config (new web sites in .NET 3.5 will already have these configurations). The first change requires adding the role service to the sectionGroup of the configuration settings:
<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>
Next, you need to enable the service from the list of web services under system.web.extensions:

ASP.NET AJAX: Client-side event viewer
Often times when an ASP.NET developer is first learning about the page lifecycle, he puts together a simple application that displays the raised events on the page. This widespread technique helps him understand the order in which the events occur, the arguments that are passed along, and ultimately what can and cannot be accomplished during each event.
