PageMethods - Type checking for your ASP.NET urls
Here's an interesting idea - setting up special methods in your ASP.NET page class to assist in generating URLS to that page. Versions for Visual Studio.NET 2003 and 2005.
PageMethods takes care of your URLs. It proposes a solution to define structured URLs for each of your pages, as well as a clean and simple way to call them.
The idea is based on strict page inputs and declarative parameter binding. With PageMethods, each page exposes a set of methods that represent the different ways to call the page. All you have to do to start benefiting from sharp URLs is to add methods to your pages, and mark these methods with attributes provided by PageMethods.
