It was initiallydeveloped to efficiently host the runtime in Microsoft SQL Server, which implements its own scheduler and memory manager.

y  New personalization features for ASP.NET, such as support for themes, skins and webparts. y It includes a new feature called Control State. Control state is similar to view state except that is used to

preserve only critical information. For example the gridview control uses control state to store theselected row. Even if you disable the viewstate, the gridview control remembers which row is selected.

y Using Profiles to store user properties - Profiles can be used to easily add personalization to your websites

y Cookieless forms authentication ± Cookieless option in web.config has further attributes such asuseDeviceProfile, useCookies, auto and useUri. The useDeviceProfile setting is the default and reads

the device profile data in the incoming HTTP header to determine whether cookies should be used. If cookies cannot be used, the authentication ticket is stored in the URI. The auto setting attempts to usecookies as a first pass, and if this fails, reverts to URI-based tickets. The useCookies and useUri force

 ASP.NET to use either cookies or URI-based tickets respectively.

y ASP.NET 2.0 controls are mobile aware, which means that a single web UI can be used to target both adesktop and mobile device. The significance of this mobile awareness in relation to cookies is thatmobile devices have traditionally been one of the trouble spots for cookies.
