The Microsoft .NET Framework version 2.0 includes significant enhancements to ASP.NET in virtually all areas. You will find that you can get Web sites and pages up and running more easily and with less code than ever before. At the same time, you can add custom features to ASP.NET to accommodate your own requirements.
ASP.NET is next-generation technology that helps you develop your own web applications and dynamic web pages. In many cases, you can develop applications easier, faster, and with less code. With ASP.NET you can deployed compiled .NET DLLs making your applications run faster. You can also run ASP.NET alongside ASP 3.0.
With ASP.NET you will find everything you need to begin building exciting, dynamic Web applications. The most interesting feature is the introduction of database-triggered cache invalidation. In ASP.NET, you can invalidate a cached item based on some pre-defined conditions such as change in an XML file or change in another cache item. Using this feature, you can remove or invalidate an item from the cache when the data or another cached item changes. This is a very common capability most applications will require. Being able to invalidate a cached item when the data in the database changes is a capability that can go a long way in revolutionizing the way ASP.NET applications are built and deployed.
