How to configure my ASP.NET application to use .NET 3.5

Hi, many say that .Net 3.5 is just an extention for version 2 so there is no need to configure the appliction to use 3.5 after I recently updated my .NET framework from version 2 to 3.5 and also installed .NET 3.5 service pack1.
After I installed .Net 3.5 I supposed our application will use 3.5 by default but when I add a property EnableHistory="true" (which supported by .NET 3.5 only) to the scriptmanager tag I got a runtime error says: "Type 'System.Web.UI.ScriptManager' does not have a public property named 'EnableHistory'" which means that I'm not using .NET 3.5!
Whhat I missed? Any suggestion?

If you right-click on the root of the app in the solution explorer (in Visual Studio) you should be able to set the target framework.

oh, the version 3.5 is not compatible with VS 2005. The compilers do not understand the language.

raji007, in that link the first statment is:
"AJAX functionality is integrated in ASP.NET 3.5 SP1 and does not require any additional downloads."
